Therefore I did the same as in the openlayers examples to show data with a WFS. But in my case, it doesn't work. After some reading in the internet i found out, that I have to configure a OpenLayers.ProxyHost to show the data with a WFS. In the examples I always found this type of code: OpenLayers.ProxyHost="/proxy/?url="; What does that mean? Furthermore I found out, that I have to configure more, when I use Tomcat. In my case I use a Server with Tomcat 5.5 installed and Geoserver to connect to WFS http://IP:PORT/geoserver/wfs What do I have to configure that I can show my data on Map over WFS.

I am working at a view that displays alarms on top of the map, and if there is a large number of alarms, one more alarm coming every 2 minutes will not catch the attention of the operator... I need a mechanism to somehow color/animate symbols loaded through KML which were not previously on the map. Symbols which dissapear between layer refreshes are not important to me. At the next refresh cycle, the highlighted symbols would no longer be highlighted (because they already exist on the map). I have a way to load KMLs periodically, avoiding the cache, but I'm missing the "highlight" mechanism. Hope I have presented my request in an understandable manner, and hope there is a solution. Maybe a property on the KML layer indicating if an item is new or not...

The server will response with correct xml (i think gml3...possible?), but if I make poly.features.length, it will return 0 instead of 3 (i have 3 features) Has anybody any ideas? maybe I have to specify the format of the response? In case, where?

The problem is that your get feature output format is gml 3.1.1, so you will have to parse the response with OpenLayers.Format.GML.v3. To instantiate this class correctly you must specify the feature typeName (without prefix) and the feature namespace, something like: var format = new OpenLayers.Format.GML.v3({ featureType: "RecintosSigpac", featureNS: "http://mapserver.gis.umn.edu/mapserver" }); Best regards, Gabriel Nolasco > ------------------------------ > > Message: 7 > Date: Tue, 3 Nov 2009 15:25:27 +0100 > From: "David Alda Fernandez de Lezea" > Subject: [OpenLayers-Users] Problems adding polygon data from GML > To: > Message-ID: > <224DBDAF88A6AC47BD22432815351BE007877F40@nekaposta1> > Content-Type: text/plain; charset="iso-8859-1" > > Hello, > > I'm having some issues trying to add a feature to a vector layer from > an WFS response.

In fact, you can build templates in geoserver to show only the results you want with a getfeatureinfo request. Thanks for the hint. But now I have an other problem. Is it possible to define more templates for one layer? For example, if the user wants output1 --> template 1 will be used by geoserver to show the results if the user wants output2 --> template 2 will be used by geoserver to show the results Is this possible?

The patches in that ticket are part of OpenLayers since version 2.6, so, yes! I'm not sure if you use styling coming from the KML file or style it all yourself. In your case I think you need to revert to the latter case. You will need to do some magic to find out what features are new and apply a different style to those items. There are few different ways of doing it. One of them might be marking it's 'newness' in an attribute of the new feature(s) and use a rule that checks that attribute in your style map.

You can retrieve them as GML or GeoJSON for example (or KML, etc) and display them in your application the way you want it. I use my own html templates with variables representing the attributes and have those replaced with their value for example.

I use geoserver and therefore I could use WFS too. But with a WFS you get only a xml (gml) I thought and i want to display the featureinfo. is this possible with wfs, too? Could you show me an example of how to integrate such an wfs (getfeature) in openlayers to show the clicked value on my map. I know that I can use a filter with wfs, but I don't know how to use it with openlayers. I'm sorry, but I'm new in openlayers and unfortunately I'm not a pro with geoserver. Thanks for your help.

It's not perfect, but it works :-) A few things to look out for: - use 'ows' in your url instead of 'wms' or 'wfs'. OWS captures both, you just need to specify the service explicitly - make sure that if your geoserver runs on another port or another machine that you have a proxy script - look at the 'propertyName' parameter. That one tells the WFS service what attributes to return. [1] http://pastebin.com/f10237f96 Good luck!

That's probably a cleaner way, but you'd have to find out how to add extra paramaters like 'propertyName' and you'd still need to loop through the attributes and show them.

When I do the layer refresh, I just do layer.refresh({force: true}); I'm not sure what this does internally, but perhaps I can't count on any attributes I set - to be preserved. Should I build the variable (hash) where I keep attributes as a different variable? Or should I keep it in a standalone object? Also, before I do the refresh - I suspect I need to copy the attributes of the current objects, issue a layer refresh and then (hoping the refresh is synchroneous) I should go through the new list and see if I have new items. If there are, mark them as new (and mark other items as 'old'). Supposing that I do that - what would I need to do to change the aspect (change color/make bigger) of the "new" items? I'm afraid this will consume some memory and resources - but I guess I will see when it's ready... How does my plan sound like?

As you suggested, you could, just before a refresh, store all features (or feature.ids) in some array, then refresh and compare the new feature list with the old one. The refresh is usually not synchronous, but that does not need to be a problem: you can register for events ('beforefeaturesadded' for example) and call your compare function with the list of new features. You can then loop through them and mark the new ones as new (for example by saying: feature.attributes.isNew = true). Make sure that the compare function itself returns true. Have a look at what's possible with styling in OpenLayes (it's a bit of a read): http://docs.openlayers.org/library/feature_styling.html So, yes, your plan sounds good!

Which WMS are you using? Maybe you can try Layer.WMS.POST (in trunk) if your WMS supports POST? Alternatively, post your string to a custom script on the server, and give back a url which you can use in the GetMap request using the SLD parameter instead.

The only browser that requires Layer.WMS.Post is Internet Explorer. Other browsers can handle long URLs in Get requests fine. Layer.WMS.Post uses Get by default in Opera and Firefox, unless you configure it with the usupportedBrowsers option set to []: var layer = new OpenLayers.Layer.WMS.Post("name", "url", { sld_body: "your sld body here" }, { unsupportedBrowsers: [] }); If it works after that change, then your server cannot handle long URLs. If it still does not work, then something is wrong with your SLD. Did you try if it validates? Or if it works when using SLD with a url reference instead of SLD_BODY?

IIRC you are using GeoServer. If that is correct, you can specify the INFO_FORMAT to be 'application/vnd.ogc.gml', then you could pass the output to the OL GML reader which looks a bit like this: var gmlReader = new OpenLayers.Format.GML(); var features = gmlReader.read(data); // assuming the result of the output is in the variable called data Then you can loop through the features and change the attribute information any way you like and visualise it any way you want.

That's a good advice. I tried it and I get back a gml with all the features .That's great. But unfortunately I can't read it with my gmlReader. What value do I have to insert at gmlreader.read(data) instead of data so that i can read my output. Thanks for the help.

If you want the flexibility you were asking for, I think you'll stay stuck until you overcome the proxy hurdle. Where do you serve your HTML from? Apache on port 80? And your GeoServer is on port 8080? If you place your proxy.cgi in your cgi-bin directory, it should work (make sure its exececutable). Or otherwise, why not setup Apache to proxy pass all requests to /geoserver/* to http://localhost:8080/geoserver/*? Then you don't need a proxy script at all.

This widget can be configured with an XML file and can act and behave like a dojo widget as well as an instance of OpenLayers.Map. I am planning to write some code that makes it possible to configure the widget declaratively or via JSON. This is all fine and well and works, with one very important exception. Panning does not work, more specific there are layers in which it doesn't work. Panning works in the Google layers because the drag and drop functionality is delegated to the Google layer. However for the "native" openlayers layers the events do fire but the map is not updated. Panning and then zooming in or out will cause the map to center on the correct point and so will panning and then resizing the window. It is not limited to a specific browser, I have tested FF3.5, IE8, IE7 emulation and Opera 10 all running on a windows XP box. My hypothesis is that there is a mix up with some events that are attached via dijit._Widget and OpenLayers.Map, but I can't find exactly where or how to fix it properly. If anyone has any suggestions at all I'd love to hear them. Any other feedback or suggestion are welcome as well. For a demo you can point the browser of your choice to http://bonsai.nmpo.nl/experiments/mapviewer.v2.html For a zip file with the source, http://bonsai.nmpo.nl/experiments/viewer.zip. If you want to see more layers you can uncomment the layers in the XML file, they all work and have the data needed to fill them is supplied in the zip as well.

In any case, OpenLayers would not be able to render anything other than a standard image (something you can put in an tag) as an externalGraphic, which is how KML files with icons are parsed. -- Chris > Is the limitation based only on browser type (and what it can render)? > Or are there other limitations I should know about? > > Thanks, > Adrian > > _______________________________________________ > Users mailing list > Users@openlayers.org > http://openlayers.org/mailman/listinfo/users -- Christopher Schmidt MetaCarta From dtoto at pdsg.com Mon Nov 9 14:11:41 2009 From: dtoto at pdsg.com (Drew Toto) Date: Wed Sep 1 17:18:11 2010 Subject: [OpenLayers-Users] Graphic line stroking?

I've considered a sloppy hack for repeating basic patterns... define a pattern and an offset, then at each offset on the line, calculate new points based on the pattern and insert them into the line's point collection. This would add a significant number of points to the line (especially with a complex pattern) and doesn't seem like a clean solution at all. Any comments are welcomed. Thanks.

I have Spherical Mercator tutorial on reprojecting vector data and I still can't figure out what I am doing wrong. I am trying to overlay on Google Layer some vector data using WFS Protocol. My problem is that whatever I do, OpenLayers request data from the server using BBOX Strategy with projection EPSG:900913 but my data is on projection EPSG:29193 and that gives me 2 problems: 1- The server gives a null response; or 2- The server gives back the xml with the data, but the projection is on 29193 and OpenLayers thinks it is on 900913, so it displays in the wrong place. Here is the code for the map options: var options = { maxExtent: new OpenLayers.Bounds(-20037508.34,-20037508.34,20037508.34,20037508.34), numZoomLevels:18, maxResolution:156543.0339, units:'m', projection: "EPSG:900913", displayProjection: new OpenLayers.Projection("EPSG:4326"), controls: [ new OpenLayers.Control.PanZoom(), new OpenLayers.Control.MouseDefaults(), new OpenLayers.Control.LayerSwitcher() ] }; And here is the code for the layer options: var layer = new OpenLayers.Layer.Vector("WFS", { strategies: [new OpenLayers.Strategy.BBOX(), saveStrategy], protocol: new OpenLayers.Protocol.WFS({ url: "http://localhost:8080/geoserver/wfs", featureType: "Regional", featureNS: "http://prodabel1062.pbh:8080/avis", geometryName: "GEOLOC", srsName: "EPSG:29193" }), projection: new OpenLayers.Projection("EPSG:29193") }); As it is, I get null response from the server. And if I change the layer projection to "EPSG:900913", I get the response, but no drawing (as it will be in the wrong projection). I have seen a thread in this list from Jachym Cepicky where he defined a handler for preFeatureInsert event and reprojected his vector data "manually". As I understand (from http://docs.openlayers.org/library/spherical_mercator.html#reprojecting-vector-data) this shouldn't be necessary, but right now I feel that is my only option left. Would you guys mind sheding some light over my problem? Thanks, Pedro. -------------- next part -------------- An HTML attachment was scrubbed...

I also changed the displayProjection on the map to EPSG:29193 and those weird numbers are confirmed by OpenLayers.Control.MousePosition. My guess is that there is some problem with the reprojection routine from 900913 to 29193. I am also guessing this may be because 29193 is limited to a region of the globe while 900913 is a world-wide projection. Does it make sense?

I didn't have proj4js loaded. I thought it came along with OL. :P It is working great now. I just have a minor issue that is the first load of the page. On firebug, the BBOX filter of the first request doesn't get reprojected to 29193, but from the second request on, the BBOX gets reprojected and the data is drawn. This might have something to do with the request being sent before proj4js is completely loaded. I used the complete version with all EPSG projections on it, and it is a 70kb compressed js file. I will try removing all the other projections from it and initializing only EPSG:29193 using "Proj4js.defs" and see if that solves the problem. Do you have any suggestion regarding this?

I have a FramedCloud popup which gets its content through an ajax call. Everything works ok (the popup is the same size as the content) if I don't change the size of the fonts in the popup. In some cases, I have to override the default font size and make it bigger. In these cases, the popup doesn't resize properly. For instance, if the content has 'font-size: 11px' it fits the popup, but if the content has 'font-size: 22px', the popup grows in height, but the width remains the same as the first case. By the way, my content is usually a table (which has applied the style='font-size: 22px;' attribute). My questions are: 1. Is this behavior a known problem or should autoResize work without problems? 2. I could call - as a workaround a function to autoRezise the popup after the ajax call completes. Question is - what is this function? (I haven't found anything in the api) 3. I could set maxSize/minSize - but I have no idea how to calculate the width/height of my content (in case there are no other workarounds I could *estimate* it based on number of characters per line + font size - but it's way too cumbersome to be a real solution) Thanks, Adrian.

This is for a set of demos and articles for GeoWebGuru.com along the lines of the recent Equal Area Map articles (demos can be seen at http://www.equal-area-maps.com ). I'm currently using the +sterea projection for dev, but I shall be extending this to other polar projections. Data is limited to the northern hemisphere. This is because some of these projections are only valid for one hemisphere, and for the remaining projections (eg. sterea) the opposing hemisphere is generally too distorted for practical use. My base map is served by WMS, and it is relatively easy to limit this to one hemisphere because I host the data and can clip the data a priori (ie. during my data prep). These demos allow a user to plot external KML or GeoRSS data at run time (implemented using OpenLayers). That currently works well, but OpenLayers is currently plotting the entire data for both hemispheres. I need to clip the GeoRSS or KML data to the northern hemisphere. The projected hemisphere is a circle. Both types of data feed use geographic coordinates, so it is much easier to clip the data as it is read (ie. only accept data where latitude >0deg). How can I do this in OpenLayers? I can't see an obvious way. I tried setting the vector layer's maxExtents - not quite what I want, but worth a try. This didn't work. It looks like a custom Strategy implementation might be the way to go? Are there any examples or documentation as to how to write a custom Strategy? At the moment I'm planning a two part article on polar projections, but if a custom strategy is required, I could write a third article on how to do this. Another thought is that I could file a feature request: To clip vector layers to a shape (or bbox) before the vector layer is re-projected. This could have other applications. For example, an application may wish to let a user limit the display of input data to an area or country of interest. Anyway, I thought I should post something first in-case this was possible already and to avoid what could be an unnecessary feature request.

Message-ID: <1258015312530-3991438.post@n2.nabble.com> Hello, As I already said in my subject I have the following problem. I have a openlayers.map with a wms. When I launch my application, my points are displayed on my map at the right position. Until now, everything is fine. But when I zoom in or zoom out my map, the points still stay at the same position, so the positon of the points isn't right after zooming (for example I have some points in Denmark, then I zoom out two times, afterwards I zoom in two times, now my points are somewhere in the ocean) I don't know why this happens. Is there someting like a redraw map, that my points stay at the right position, even when i zoom in or zoom out? Or can I solve this problem an other way? Thanks for your answers.

Where is the mistake? Is the OpenLayers code served by http://localhost:8080 too ? If this is the case you may need to tweak 'featureNS' to match the namespace found in the WFS returned by geoserver. At least I had to change it to "http://mapserver.gis.umn.edu/mapserver" for that to work with mapserver. --strk; Free GIS & Flash consultant/developer () ASCII Ribbon Campaign http://foo.keybit.net/~strk/services.html /\ Keep it simple!

By default, it's in degrees [1]. Plus, the maxExtent should be in meters too (try using the one from your mapfile). If it's still not working, you can try watching the request built from OpenLayers in Firebug and see the response. There may more more clues there.

If you can't wait for me to be finished you might want to experiment yourself a bit. It's easy to create a canvas element and add images to it so you might want to get the WMS requests from the layers and add them to a canvas for saving. Of course I'm assuming that your map consists of WMS layers only now.

It is not possible to do this (universally) in the browser.

I'm able to use them with Google Maps and Bing Maps, but now I'd like to use them with OpenLayers. I've created the layers and I'm "sort of" able to get them to display on the map, but they don't seem to match up with other map layers that I have in OL. I'm almost certain it has to do with my projections, or "resolutions" settings, or something along those lines, but I don't have enough mapping experience to understand exactly where I'm going wrong. Does anyone have any examples of using MapCruncher-created tiles in OpenLayers - and is it even possible, given the output of MapCruncher? Are there specific scales or zoom levels or other specific settings I need to have configured properly in order to display these tiles in OL?

I have several overlays, and I want them to be queryable when they are turned on (visible) only. But I found if I turn on two or more overlays, only 1 layer can be queried and other visible overlays give no result (empty template in mapfile). Here is my code: map.events.register('click', map, function (e) { var oplayers = new Array( alayer.visibility, blayer.visibility, clayer.visibility, dlayer.visibility, elayer.visibility, flayer.visibility); var mslayers = new Array("a","b","c","d","e","f"); var i=0; for (i=0; i < 7; i++) { if ( oplayers[i] == true ) { var url = "http://localhost/cgi-bin/mapserv.exe" + "?map=c:/ms4w/Apache/htdocs/mapfile.map" + "&REQUEST=GetFeatureInfo" + "&VERSION=1.1.1" + "&EXCEPTIONS=application/vnd.ogc.se_xml" + "&BBOX=" + map.getExtent().toBBOX() + "&X=" + e.xy.x + "&Y=" + e.xy.y + "&INFO_FORMAT=text/html" + "&QUERY_LAYERS=" + mslayers[i] + "&LAYERS=" + mslayers[i] + "&FEATURE_COUNT=1" + "&SRS=EPSG:4269" + "&STYLES=" + "&WIDTH=" + map.size.w + "&HEIGHT=" + map.size.h; window.open(url, "getfeatureinfo", "location=0,status=0,scrollbars=1,width=600,height=400" ); }; }; }); alayer,blayer,clayer,dlayer,elayer,flayer are names of layers defined in html. (var alayer = ......) a,b,c,d,e,f are the layer names of the mapfiles. The only querable layer is the 'highest' one. For example, if I turn on alayer and blayer, blayer can be queried but alayer cannot. If alayer, blayer and flayer are on, only flayer can be queried. I find that the layer with higher variable i ([ oplayer[i] ]) would be queried only. I know there is a function called WMSfeatureGetinfo but I don't know how to use it. I just know it has queryVisible which can filter the hidden layers, but error 'permission denied' always comes out when I click on the query layer. I prefer my method, and I think the logic of my code is okay but something is wrong. Can anyone get idea about that?

I "streched" the popup window to use the whole width. I looked into openlayers/lib/OpenLayers/Popup/FramedCloud.js and expanded the default sizes for the image and the popup to fit the new image size. If I test this setup, the popup extends ok around my content, but the right-most side of the popup loses its rounded corners. Also the "connector" (I guess it's called a stem) between the marker and the popup is sometimes distorted or blank. This has to do with the definitions of offsets in the positionBlocks. Eg: positionBlocks: { "tl": { 'offset': new OpenLayers.Pixel(44, 0), 'padding': new OpenLayers.Bounds(8, 40, 8, 9), 'blocks': [ { // top-left size: new OpenLayers.Size('auto', 'auto'), anchor: new OpenLayers.Bounds(0, 51, 22, 0), position: new OpenLayers.Pixel(0, 0) }, { //top-right size: new OpenLayers.Size(22, 'auto'), anchor: new OpenLayers.Bounds(null, 50, 0, 0), position: new OpenLayers.Pixel(-638, 0) }, { //bottom-left size: new OpenLayers.Size('auto', 19), anchor: new OpenLayers.Bounds(0, 32, 22, null), position: new OpenLayers.Pixel(0, -631) }, { //bottom-right size: new OpenLayers.Size(22, 18), anchor: new OpenLayers.Bounds(null, 32, 0, null), position: new OpenLayers.Pixel(-638, -632) }, { // stem size: new OpenLayers.Size(81, 35), anchor: new OpenLayers.Bounds(null, 0, 0, null), position: new OpenLayers.Pixel(0, -688) } ] }, ... Can somebody explain the following: 1. bottom-right, bottom-left, top-right, top-left are intended to "carve-out" the rounded popup corners? 2. what is "stem" supposed to be? 3. How is the position coordinates measured from the file? What do negative coordinates mean (are they measuring from right to left)? 4. Is there a more automated way to update these offsets from a file - or should they be imputed by hand - and trial and error? 5. Is anyone else interested in wider popups? Usualy you shouldn't need them on normal screens, but I need to display them on large 4000x4000 screens... If there are people interested, I will submit a patch... 6. Oh - is there a way to get wider popups without editing the image/offsets? I guess the background of the picture is not "streched" to fit the popup (current behavior).

What I want to really do is to get some data from an external service in a predefined structure and parse it using XSL and my predefined SLD, to get a final SLD xml file and apply it to the layer, that's the reason because I had those tags. You should apply it to the polygon layer. What WMS are you using? Mapserver? Try to put your SLD XML on a webserver and reference it with the SLD parameter without the use of OpenLayers in between. If this does not work, you might have better luck asking on the mailing list of your server product. Have you tried without the xsl stuff embedded in your XML?

The last wins. If you change the window name to "getfeatureinfo" + i, then you should get one window for every query. A second approach is to collect the visibible layers and do only one getfeatureinfo request with this layerlist. Then you get back from MapServer one result html for all the queried layers. Arnd -----Urspr?ngliche Nachricht----- Von: users-bounces@openlayers.org [mailto:users-bounces@openlayers.org] Im Auftrag von Aypes2 Gesendet: Freitag, 13. November 2009 08:24 An: users@openlayers.org Betreff: [OpenLayers-Users] Query problem Dear all, I just got a query problem. I have several overlays, and I want them to be queryable when they are turned on (visible) only. But I found if I turn on two or more overlays, only 1 layer can be queried and other visible overlays give no result (empty template in mapfile). Here is my code: map.events.register('click', map, function (e) { var oplayers = new Array( alayer.visibility, blayer.visibility, clayer.visibility, dlayer.visibility, elayer.visibility, flayer.visibility); var mslayers = new Array("a","b","c","d","e","f"); var i=0; for (i=0; i < 7; i++) { if ( oplayers[i] == true ) { var url = "http://localhost/cgi-bin/mapserv.exe" + "?map=c:/ms4w/Apache/htdocs/mapfile.map" + "&REQUEST=GetFeatureInfo" + "&VERSION=1.1.1" + "&EXCEPTIONS=application/vnd.ogc.se_xml" + "&BBOX=" + map.getExtent().toBBOX() + "&X=" + e.xy.x + "&Y=" + e.xy.y + "&INFO_FORMAT=text/html" + "&QUERY_LAYERS=" + mslayers[i] + "&LAYERS=" + mslayers[i] + "&FEATURE_COUNT=1" + "&SRS=EPSG:4269" + "&STYLES=" + "&WIDTH=" + map.size.w + "&HEIGHT=" + map.size.h; window.open(url, "getfeatureinfo", "location=0,status=0,scrollbars=1,width=600,height=400" ); }; }; }); alayer,blayer,clayer,dlayer,elayer,flayer are names of layers defined in html. (var alayer = ......) a,b,c,d,e,f are the layer names of the mapfiles. The only querable layer is the 'highest' one. For example, if I turn on alayer and blayer, blayer can be queried but alayer cannot. If alayer, blayer and flayer are on, only flayer can be queried. I find that the layer with higher variable i ([ oplayer[i] ]) would be queried only. I know there is a function called WMSfeatureGetinfo but I don't know how to use it. I just know it has queryVisible which can filter the hidden layers, but error 'permission denied' always comes out when I click on the query layer. I prefer my method, and I think the logic of my code is okay but something is wrong. Can anyone get idea about that?

The error that I posted before was because MapServer couldn't find the sld file. And now, I don't know why the code I posted the first time works. Maybe was some kind of syntax error or something like that. By the way, I create the SLD on the fly using XSL and in the resultant XML I maintain those XSL tags, and it works, just to let you know.

Please make sure that the sld url is valid and that imagepath and imageurl are set properly in the map file This is the first time I see this error. What I want to really do is to get some data from an external service in a predefined structure and parse it using XSL and my predefined SLD, to get a final SLD xml file and apply it to the layer, that's the reason because I had those tags. You should apply it to the polygon layer. What WMS are you using? Mapserver? Try to put your SLD XML on a webserver and reference it with the SLD parameter without the use of OpenLayers in between. If this does not work, you might have better luck asking on the mailing list of your server product. Have you tried without the xsl stuff embedded in your XML? Also, things like PropertyIsEqualTo etc need to be in the ogc prefix, not sure if this is the problem though (some WMS-s are quite permissive).

I just installed the proxy plugin and the example with google http://[your_geoserver_domain]/geoserver/rest/proxy?url=http://www.google.com works. so the proxy is working. Now my problem is, what for a hostname do I have to enter, that my application will run. Do I have to enter my IP, or the IP, where geoserver runs, or something else.

I already know, that i have to configure a proxy that I can do this. With geoserver you have the opportunity to install a plugin called ProxyExtension, to do exactly this. http://geoserver.org/display/GEOS/GeoServer+Proxy+Extension I installed the plugin and the example with the redirect to google works (http://[your_geoserver_domain]/geoserver/rest/proxy?url=http://www.google.com) --> the proxy is installed correctly. But now there are the next problems. 1. What for a hostname do i have to configure (Do i have to enter the ip of my pc, or the ip of the geoserver pc, ...?) 2. Do I have to set up a Openlayers.proxyhost in my program. How would this look like in my case? I hope someone can help me with this problem. I already tried so many different things, but nothing worked. (Either I get no response text in firebug or I get a bad request) Thanks for your answers.

Cliff Dyer) Date: Wed Sep 1 17:18:12 2010 Subject: [OpenLayers-Users] Trying to draw a box on a map, and get the coordinates back. Message-ID: <1258129691.25288.30.camel@aalcdl07> I'm trying to draw a box on a map, have it persist until another box gets drawn, and submit the coordinates of the box to a form. I'm doing this to allow the user to search for objects within a given area. I'm doing this by using an OpenLayers.Handler.Box tool in a custom OpenLayers.Control, which then uses to the "done" callback of the draw method to create (or recreate) an OpenLayers.Feature.Vector and populate (or repopulate) a search form. My immediate problem is that the persistent box is not in quite the same location as the box the user just drew. I suspect this has something to do with projections, but since I never explicitly set projections, I'm not sure where the error sneaked in. More generally, I'm not sure I'm taking the optimal route from the bounds passed to the callback to the Vector feature. Currently, I do the following: 1) Take the incoming OpenLayers.Bounds object, 2) Get an OpenLayers.Pixel from the the corners 3) Get the coordinates of each pixel using map.getLonLatFromPixel 4) Create a new OpenLayers.Bounds 5) Extend it to my new coordinates 6) Convert it to a geometry 7) Convert it to an OpenLayers.Feature.Vector Then I take the coordinates from step 3) and populate a form with them, which I then submit to my application server side. The code for this is pasted here: http://pastebin.com/m300c24a5 Any pointers on how to do this more cleanly would be much appreciated.

In-Reply-To: <1258129691.25288.30.camel@aalcdl07> References: <1258129691.25288.30.camel@aalcdl07> Message-ID: <4AFD9045.2060001@nsidc.org> I did something like this using one of the examples on the OpenLayers site, modified slightly. Here's what I used: boxControl = new OpenLayers.Control(); OpenLayers.Util.extend(boxControl, { draw: function() { this.box = new OpenLayers.Handler.RegularPolygon(boxControl, {"done": this.notice}, {sides:4, irregular:true, persist:true}); this.box.activate(); }, notice: function(geom) { // whatever you want it to do after the box has been drawn } }); // then add the boxControl to the map This works pretty nicely. Note that "geom" will be in the same projection as the map, so if you want the output to be in another projection (like a latitude/longitude display) you will have to go through the geometry and transform the points. Also, you may have to go through the geometry to determine which point is which (it doesn't always start with the upper-left corner, and it's not always clockwise or counter-clockwise). If interested, I can post some of the functions I do for that. I hope this helps, Scott Lewis NSIDC J.

Perhaps you can help me. I will have a simple imgage (jpg, png, gif, ?) from my mapview. I will have a button on my side and if the user presses this button you can save the actual mapview with all shown layers in the shown scale and so on as an image. Like a screenshot from the map-div for example. The format is not so important. I don?t know if it is possible. Perhaps this is not the right forum, but perhaps somebody can help me.

That's definitely a cleaner setup, but it didn't really solve the problem I was having. Before the box would look like it was being drawn properly, but then the persistent copy would be vertically offset. Now it's offset from the time I start drawing. Which is an improvement, because at least it will be easier for users to draw the box they want. Here's a screenshot to show what I mean: http://imgur.com/5cJ4H The Box was drawn exactly from Cape Fear to Cape Hatteras, marked with little black dots on the screenshot. However, the box itself starts drawing a bit above the location of the cursor. It seems the further I get from the top of the display, the further displaced the box is. It is impossible to get closer than ~2cm from the bottom of the map. There also seems to be a very slight horizontal displacement. Any thoughts on what might cause this displacement? At this point, no transformation is being done--at least not in any of my code.

Can you give a bit more information on what your setup looks like? Do you use Apache for example or another web server? Does GS run by itself or in Tomcat for example? Have you ever tried downloading an OL 2.8 zip file, extracting it somewhere in your document root in Apache (for example) and run the OL examples, WFS ones in particular? Because if those work, the proxy.cgi in the examples dir works. You can then add 'localhost:8080' to allowedHosts (in proxy.cgi) and try your app from that directory. Once that works, you can move your app somewhere else and put proxy.cgi in a better place and get it to work.

When users select one of the markers the permalink will be updated to include the id of the selected feature. This works all fine. The problem comes when users click on the permalink. This click will not only activate the permalink but also trigger a mouseout event on the vector layer which unselects the current feature and updates the permalink. This happens before the browser follows the link which makes it impossible to follow a permalink with a selected feature. I tried to add an event listener to the permalink control in the hope of catching and stopping the click event before it falls through to the map. However, for some reason the event handler is not called. This is the code I used for adding the event listener: this.permalink_control = new OpenLayers.Control.Permalink(null, null, { eventListeners: { "click": function(e) { alert("Test"); OpenLayers.Event.stop(e ? e: window.event); } }}); this.map.addControl(this.permalink_control); this.permalink_control.activate(); Is this the correct way to add an event listener? And would it solve the original problem? Please note that the application does not use the default SelectFeature control but a custom one which includes a Drag handler in addition to the Feature handler. I compared the handling of clickout events in the SelectFeature control and in my control and could not find any differences that might affect the permalink.

I read your post from a while back on using arbitrary projections with OpenLayers - I'm wondering if you've had any success? I'm trying to serve tiles created with MapCruncher and display them with OL, without having anything set as a "base map" - primarily for the reasons you mentioned - performance (we're hosting them on Amazon S3). The problem we're having is getting the tiles to display properly in the various coordinate systems - we have existing tiles that were created with GeoWeb Cache, and we're trying to figure out to make all of these layers "switchable" in OL, and to make the coordinate systems match up so that we can draw vector graphics using standard lat/lon notation instead of meters. Any pointers you could offer would be greatly appreciated - we'd be willing to pay for an answer :) From roald.dewit at lisasoft.com Sun Nov 15 15:43:20 2009 From: roald.dewit at lisasoft.com (Roald de Wit) Date: Wed Sep 1 17:18:13 2010 Subject: [OpenLayers-Users] Using MapCruncher-produced tiles with OpenLayers; We'll pay someone :) In-Reply-To: <1258296407303-4007748.post@n2.nabble.com> References: <1258296407303-4007748.post@n2.nabble.com> Message-ID: <4B0067E8.7020804@lisasoft.com> Hi, Maybe you can show an example of what goes wrong. I've never used MapCruncher. From their site, it seems that it should output in spherical mercator projection [1]. That means that your base maps and any other raster layers must be in that projection too. Vector layers can be reprojected if need be.

AFAIK you cannot register a browser event listener on a control's DOM element using eventListeners (or control.events.register). Have you tried OpenLayers.Event.observe(control.element, "click", function(e) { ... }); ? cheers, -- Eric Lemoine Camptocamp France SAS Savoie Technolac, BP 352 73377 Le Bourget du Lac, Cedex Tel : 00 33 4 79 44 44 96 Mail : eric.lemoine@camptocamp.com http://www.camptocamp.com From eric.lemoine at camptocamp.com Mon Nov 16 00:51:09 2009 From: eric.lemoine at camptocamp.com (Eric Lemoine) Date: Wed Sep 1 17:18:13 2010 Subject: [OpenLayers-Users] Huge amount of data crashing browser In-Reply-To: <5e3c00490911121001w4785e338nbdd2471d87e3dc21@mail.gmail.com> References: <5e3c00490911121001w4785e338nbdd2471d87e3dc21@mail.gmail.com> Message-ID: On Thursday, November 12, 2009, Pedro Baracho wrote: > Hello all, > > I have huge amount of data being retrieved on a Vector Layer and it is crashing the browser (lack of memory) when it tries rendering it. > > I am thinking of using MinResolution, MinExtent and doing some search on current strategies to crop the data, or show the layer only in a determinate level of zoom. > > Any suggestions? you may be interested to look at the BBOX and Cluster strategies.

I have installed GS version 2.0 itself (without tomcat or something else). I copied the OpenLayers folder (with examples...) into my geoserver home_directory and started the examples. but the wfs didn't work. Because nothing worked, I installed geoserver on the same pc as my application is running (for testing). But the dissappointing fact is, that the wfs isn't running too, even when app and geoserver is on the same pc. Or does this matter, where geoserver is running, when the layer in geoserver gets his data from a database (oracle) which is on an other pc. (because that is the fact in my case).

Message-ID: Hi, I have about 2000 points in a map, distributed in 4 categories (about 500 points per category). If I try to add all the points at a time, it takes a lot of time to load all the points, and I would like to know if it is possible to create four "layers" (I don't know if the word layer fits to what I'm saying..) each one containing the points of a category, and then load the "layers". This would make the loading much faster. I need also that all the points can have their own events, like the click on a marker. Which is the best way to fit what I'm saying? I need a map server or there is any way to make this without creating a custom map with points? Thanks a lot! -------------- next part -------------- An HTML attachment was scrubbed...

That is why I suggest you recheck carefully your projections and if there are any events declared on your code for zooming. Cheers, Pedro.

What do you mean by home_directory? $GEOSERVER_DATA_DIR/www/ would be the place to put your html stuff, and then you would access it from http://localhost:8080/geoserver/www/ Now if you use the GeoServer proxy extension in this context, you have to add localhost to the Permitted Hostnames.

You could split them manually and load 4 different layers from 4 different files for example. And there is also something called Strategy on OL's Vector Layers, that is an automatic way to crop/reduce the amount of data you are showing. I can't say what is the best way, because I don't know how your points are stored. You don't need a map server, if you are splitting them manually or using "Strategy" parameter. If you intend to use OGC Filter you will probably need a OGC-Compliant map server, like Geoserver, for example.

I don't think they are on EPSG:900913 as your code states. They are most likely on EPSG:4326 (longitude and latitudes). So you should change your vector_layer projection to EPSG:4326. I also suggest you to do this: 1- Add a displayProjection option to your map variable. map = new OpenLayers.Map('map', {displayProjection: new OpenLayers.Projection("EPSG:4326")}); 2- Add a div for OpenLayers.Control.MousePosition at the bottom of your map:
3- Add OpenLayers.Control.MousePosition map.addControl(new OpenLayers.Control.MousePosition({element: $('location')})); This way you will actually see the coordinates where your mouse is pointing on the projection you want. Another thing. OpenLayers only have built-in support to EPSG:4326 and 900913. So any other projections besides those, you will have to add Proj4JS too.

I use the following code. It's a wms (my base layer) with a background card and a wfs with some points located somewhere in denmark.

WFS Points

Using a Layer.WFS with a featureClass, one can take in XML data from a WFS class and display it any way you like.

The wms is working, the wfs not. My browser (Internet explorer) tells me an error at the xmlhttprequest (Access denied). Thanks for your help.

I don't know if it is a good solution, because as far as I know, it changes the style of the layer for all the users. I would need to replicate styles on the server for each user and each layer. And also this requires the server to be Geoserver, and breaks OGC compatibility. 2- WMS 1.3 and SLD MapServer implements WMS 1.3 and accepts a SLD description in the request. GeoServer doesn't. Nothing against MapServer, but my current development environment is set with GeoServer.. 3- WFS and treat SLD exhibition on the client This is a double edged solution. The good thing about WFS is that I have many more possibilities of control over the map. I can use SelectFeature control, instead of hacking some code to implement it over WMS. But it also gives me many other options I don't need such as the vector data. I only need the images. So right now I am between solutions 2 and 3. I don't want to give up on GeoServer, but I am also having problems dealing with the huge amount of vector data that WFS is retrieving. Any suggestion will be greatly appreciated. -------------- next part -------------- An HTML attachment was scrubbed...

Ah yes, this does the trick! Thanks a lot. Here is my actual solution in case someone has a similar problem. The $$() function is part of prototype.js and allows me to address the a element of the permalink easily: OpenLayers.Event.observe( $$("." + this.permalink_control.displayClass + " a")[0], "click", function(evt) { var e = evt ? evt : window.event; // "Follow" the link because the browser does not // handle the click event anymore): location.href = OpenLayers.Event.element(e).href; // And stop the event from falling through to the map: OpenLayers.Event.stop(e); return false; } ); Cheers, Christoph From pedropbaracho at gmail.com Mon Nov 16 15:36:12 2009 From: pedropbaracho at gmail.com (Pedro Baracho) Date: Wed Sep 1 17:18:13 2010 Subject: [OpenLayers-Users] SLD on the fly In-Reply-To: References: <5e3c00490911161129s2cd33feew7fcbb91d00509ec9@mail.gmail.com> Message-ID: <5e3c00490911161236s41620917pdbf483005c8e1e2c@mail.gmail.com> Wow, I am impressed! What a cool map that is being displayed on my screen! hehe :) Thanks for the reply. Guess I am set in solution 2. Just another question. I don't see SLD BODY on WMS Spec, but I see it on SLD profile for WMS. And it also states: "GetMap is defined in WMS 1.3. The SLD profile for WMS defines additional parameters allowing clients to request layers to be portrayed according to some specified style." Do you know any map server that doesn't support SLD profile for WMS, but supports WMS? I am just curious about it, because imho it doesn't make sense splitting SLD profile for WMS from WMS spec.

This allows you to apply SLDs externally with no effect on STYLES but you can also undertake a PutStyles if you have that access privilege which will add/update the STYLE. I build a library of SLDs if I want to keep them as permanent filters which is important in my case as I am producing an infinite number of thematic maps (DemographicDrapes) from Census statistics. Have a look at http://demos.numaps.com.au/demographicdrapes.html I have built a complex Style Builder application that allows the user to pretty much change all aspects of a SLD and Save or SaveAs.

What a cool map that is being displayed on my screen! hehe :) Thanks for the reply. Guess I am set in solution 2. Just another question. I don't see SLD BODY on WMS Spec, but I see it on SLD profile for WMS. And it also states: "GetMap is defined in WMS 1.3. The SLD profile for WMS defines additional parameters allowing clients to request layers to be portrayed according to some specified style." Do you know any map server that doesn't support SLD profile for WMS, but supports WMS? I am just curious about it, because imho it doesn't make sense splitting SLD profile for WMS from WMS spec.

I find weird that Geoserver, running on my machine, can retrieve the vector data from Oracle Server, render an image and deliver it to the browser, while the browser itself, can't take the XML and render an image. And it is not a performance issue. It simply consumes all my physical memory (that is something like 4.5+ gb) and FF crashes, without any warning or error logging from OL.

I have done what you said with "getfeatureinfo" + i, when I click each time, there are one window for each query. But how can I open 1 window only when querying? I have 6 layers, and if I turn on 6 layers, 6 windows come out when clicking on the map. Only 1 windows contains information but others are useless ("EMPTY" template in MapServer). I want the required window comes out only and the "EMPTY" template comes out when clicked coordinates have nothing. I think I should write some more 'if' statements to make it work, but I have no idea about how to do this. I tried to compare the layer's coordinates/pixels with e.xy.x and e.xy.y, so window comes out only when they are same. But it fails, maybe I get the layer's coordinates wrongly. I also tried to make mslayers[i] in ("&QUERY_LAYERS=" + mslayers[i]) in which window comes out when mslayers[i] is not empty template, but fails too. I got your second approach idea. But is that using WMSfeaturegetinfo or my method? And it sounds like giving all queryable layers' information within one window only, right?

I want the default behavior for a click and shiftClick, I just want to stop the event propagating to the browser. I have a feeling this could be a bug, as I had a look at the selectFeature in Firebug, and the control contains a feature handler, and the stopClick property is set to true. So it should stop the click reaching the browser. On the tag issue, there is no tag, the images are rendered using a styleMap and the externalGraphic property. Openlayers uses SVG to render the image on the map - It is just default FF behavior. In the end I have given up using multipleKey: "shiftKey" in the control, and have settled for using toggle: true instead. Thanks for the help.

Message-ID: <1258427761415-4016339.post@n2.nabble.com> Hello, I am using OpenLayers 2.8 and based on multiple examples I found, I use the following to load a Google Map map layer: ------------------------------ var options = { projection: new OpenLayers.Projection("EPSG:900913"), units: "m", maxResolution: 156543.0339, maxExtent: new OpenLayers.Bounds(-20037508.34, -20037508.34, 20037508.34, 20037508.34) }; map = new OpenLayers.Map('map', options); var layer = new OpenLayers.Layer.Google("Google", {"sphericalMercator": true}); map.addLayer(layer); ------------------------------ I do indeed get the google map layer displayed but what I ran into is that these options change how the OL API handles or deals with latlon coordinates. For example, when I click on the map I get the following type of "coordinate" when calling the OL getLatLongFromViewportPX() function: (Lat: -39135.7584 / Lon: -273950.3093). If I do a map.getExtent(), which typically returns the latlon for the SW and NE boundary corners, now returns a value like -381458.9896 / -722521.0097, -322984.6629 / -686366.2955. These are obviously not coordinates in degrees but some other value. My application is expecting a decimal coordinate in degrees, which OL returns in the getgetLatLongFromViewportPX() and getExtent() function calls when google maps are not used. Now the app does not work. I see that the "unit" value listed in the options is "m". Not sure if that is meters or some other value. The OpenLayers.Bounds value also does not seem to be listed in a latlon coordinate. In order to get my coordinate values in degrees, is there another set of options to use or is there some formula/algorithm that can be applied to what comes back from the OL functions in order to get the value I am looking for.

You can reproject lonlat, bounds and geometry objects to EPSG:4326 using the transform method: obj.transform( new OpenLayers.Projection("EPSG:900913"), new OpenLayers.Projection("EPSG:4326") ); where obj is a LonLat, Bounds or Geometry object.

OpenLayers renders the WMS layer perfectly, but the WFS layer doesn't show up. I am pretty sure that the OpenLayers is sending an appropriate request to the server (Geoserver) and the server is also responding properly, since: 1. Geoserver is on the same server where my own application (which hosts the OpenLayers.js) is. So there's no need for the proxy. 2. Geoserver console logs show that it has received the request properly. 3. When I copy the the request string in the address bar of my web browser, I get the gml2 file from the server (I also tested the server with uDig as the client, and it can render the features properly through WFS service provided by Geoserver). Could you please help me on this issue and tell me what might be the cause of this problem? I have copied the init function from the WFS example available in the examples directory of OpenLayers 2.8 and added my own WMS layer, removed the proxy setting, and changed the WFS setting.

This could be the key to solving your problem. Your users won't run OpenLayers off visual studio. You will have an httpd (in your case probably IIS), and you need to configure that to provide GeoServer at the same origin. IIRC this is called "Virtual Folder" (or even Proxy) in IIS.

This allows you to apply SLDs externally with no effect on STYLES but you can also undertake a PutStyles if you have that access privilege which will add/update the STYLE. I build a library of SLDs if I want to keep them as permanent filters which is important in my case as I am producing an infinite number of thematic maps (DemographicDrapes) from Census statistics. Have a look at http://demos.numaps.com.au/demographicdrapes.html I have built a complex Style Builder application that allows the user to pretty much change all aspects of a SLD and Save or SaveAs.

What a cool map that is being displayed on my screen! hehe :) Thanks for the reply. Guess I am set in solution 2. Just another question. I don't see SLD BODY on WMS Spec, but I see it on SLD profile for WMS. And it also states: "GetMap is defined in WMS 1.3. The SLD profile for WMS defines additional parameters allowing clients to request layers to be portrayed according to some specified style." Do you know any map server that doesn't support SLD profile for WMS, but supports WMS? I am just curious about it, because imho it doesn't make sense splitting SLD profile for WMS from WMS spec.

At the moment i have the following situation. When I launch my example app as a file, I get an error (xmlhttprequest). Then i copied the example code in my visualstudio and made a asp.net application. There, when I launch my application, the app starts as html (not as a file) in this case I don't get an error, but the dissapointing fact is, that I don't see the points of my wfs (only the wms is shown). It's really great that I don't get an xmlhttprequest anymore, but my wfs is still not visible. Is my code correct?

The browser *isn't rendering an image*. That's the key difference. (And in fact, the browser probably could render an image like this -- via the Canvas technology -- but OpenLayers doesn't have an implementation which makes this possible.) > And it is > not a performance issue.

"Large use of memory" is performance related. The browser is generating an SVG document. If GeoServer could generate SVG (I don't know if it can) and you were to open the resulting, complex, SVG document in Firefox, it is likely you would see similar behavior. It wouldn't be exactly the same because OpenLayers does *much more* to ensure that the data you download from GeoServer is usable in the browser -- adding events, mapping colors, drawing based on style rules, etc. In addition, this manipulation is done through a notoriously heavy API -- the DOM. Rasterizing an image and vectorizing a set of data are two entirely different tasks, with different use cases, and different performance metrics. > I know that rendering and delivering an image is a lot simpler than building > nested divs and image tags, parsing XML, etc. Even more if you compare Java > to Javascript. But is it really "4gb+ simple"? That is what I find weird. Yes. It really is. Welcome to the browser.

I have done what you said with "getfeatureinfo" + i, when I click each time, there are one window for each query. But how can I open 1 window only when querying? I have 6 layers, and if I turn on 6 layers, 6 windows come out when clicking on the map. Only 1 windows contains information but others are useless ("EMPTY" template in MapServer). I want the required window comes out only and the "EMPTY" template comes out when clicked coordinates have nothing. I think I should write some more 'if' statements to make it work, but I have no idea about how to do this. I tried to compare the layer's coordinates/pixels with e.xy.x and e.xy.y, so window comes out only when they are same. But it fails, maybe I get the layer's coordinates wrongly. I also tried to make mslayers[i] in ("&QUERY_LAYERS=" + mslayers[i]) in which window comes out when mslayers[i] is not empty template, but fails too. I got your second approach idea. But is that using WMSfeaturegetinfo or my method? And it sounds like giving all queryable layers' information within one window only, right?

This allows you to apply SLDs externally with no effect on STYLES but you can also undertake a PutStyles if you have that access privilege which will add/update the STYLE.

Have a look at http://demos.numaps.com.au/demographicdrapes.html I have built a complex Style Builder application that allows the user to pretty much change all aspects of a SLD and Save or SaveAs.

I don't see SLD BODY on WMS Spec, but I see it on SLD profile for WMS. And it also states: "GetMap is defined in WMS 1.3. The SLD profile for WMS defines additional parameters allowing clients to request layers to be portrayed according to some specified style." Do you know any map server that doesn't support SLD profile for WMS, but supports WMS? I am just curious about it, because imho it doesn't make sense splitting SLD profile for WMS from WMS spec.

My Point now is listed in decimal lat/lon. I though that would solve my problem but it looks like something else is not working. When I use that new transformed Point to add an icon to the map, the icon gets added to the 0,0 location regardless of that the Point's lat/long value is. It seems like the internal API code is having problems dealing with the transformed value and doesn't know how to place it on the map using a lat/lon, so it simply places it at 0,0. ------------------------------- var lonlat = map.getLonLatFromViewPortPx(e.xy); var point = new OpenLayers.Geometry.Point(lonlat.lon, lonlat.lat); point.transform( new OpenLayers.Projection("EPSG:900913"), new OpenLayers.Projection("EPSG:4326") ); var iconSize = new OpenLayers.Size(16, 16); var iconURL = MY_ICON; var iconOffset = new OpenLayers.Pixel(8,8); var marker = new OpenLayers.Marker( new OpenLayers.LonLat(point.x, point.y), new OpenLayers.Icon(iconURL,iconSize,iconOffset)); getMarkersLayer().addMarker(marker); -------------------------------- The same also happens if I created a OpenLayers.Feature.Vector type of point. So, while the transform function allowed me to get the location as a decimal lat/lon, it doesn't appear that I can use that value to add a map icon to that location. Is there some additional transformation that needs to occur. It would seem that this would be a common thing to do. Any new thoughts as to what I am missing?

You've been right, the problem was with projection. It's resolved but the WFS features do not show up. Before you mentioned that it might be a projection problem, I copied the request string (obtained by getFullRequestString function of WFS class) in the address bar and I received a GML2 file with some features. However, that request string doesn't include the BBOX parameter. I took your advice and fixed the SRS settings on the server and client. When I copy the request string (obtained from the log file of the Geoserver which has the BBOX parameter in it) to the address bar, the returned GML2 file contains only those features which are in the BBOX. Before fixing the projection problem, this file doesn't have any feature member (an almost empty GML2 file). As I mentioned before, I cannot see the features on the screen yet. The SRS settings on the server for this layer are as follows: native srs: EPSG:32639 declared srs: EPSG:32639 srs handling: keep native And my script is the following: var map, layer, wfs; function init() { var bounds = new OpenLayers.Bounds(431834.067, 3887548.528, 684784.466, 4002241.703); var options = { maxExtent : bounds, maxResolution : 859.9516562499998, projection : "EPSG:32639" }; map = new OpenLayers.Map('map', options); layer = new OpenLayers.Layer.WMS("OpenLayers WMS", "http://localhost:8080/geoserver/wms", { layers : 'naji:TBL_GIS_ARC' }); wfs = new OpenLayers.Layer.WFS("WFS", "http://localhost:8080/geoserver/wfs", { typename : "naji:TBL_GIS_FEATURE_POINT", maxfeatures : 1000, format : OpenLayers.Format.GML.v2 }); wfs.isBaseLayer = true; map.addLayer(layer); map.addLayer(wfs); map.addControl(new OpenLayers.Control.LayerSwitcher()); map.zoomToExtent(bounds); } Last point: I am using the "full" OL instance and the Geoserver is on the same machine where the above script is hosted. I am completely stuck at this point, and would appreciate any help.

To change a layer's opacity I just use the following method >> layerObjectName.setOpacity(newOpacity); Where 'newOpacity' is a real number between 0 and 1 [0=transparent and 1=opaque therefore 0.5=half transparent etc]. Then all you need is some GUI tool to collect the number from the user. Hope that helps. Brad....

It seems that some features cannot be used in OL, for example putting the text label in the centroid of the polygon or fill-opacity (I can't make this work, even with mapserver). I've been looking to your web page and I've realized that you have a slider bar which lets you set some transparency to the style. How do you do that, if I can ask?? Thanks.

This allows you to apply SLDs externally with no effect on STYLES but you can also undertake a PutStyles if you have that access privilege which will add/update the STYLE. I build a library of SLDs if I want to keep them as permanent filters which is important in my case as I am producing an infinite number of thematic maps (DemographicDrapes) from Census statistics. Have a look at http://demos.numaps.com.au/demographicdrapes.html I have built a complex Style Builder application that allows the user to pretty much change all aspects of a SLD and Save or SaveAs.

What a cool map that is being displayed on my screen! hehe :) Thanks for the reply. Guess I am set in solution 2. Just another question. I don't see SLD BODY on WMS Spec, but I see it on SLD profile for WMS. And it also states: "GetMap is defined in WMS 1.3. The SLD profile for WMS defines additional parameters allowing clients to request layers to be portrayed according to some specified style." Do you know any map server that doesn't support SLD profile for WMS, but supports WMS? I am just curious about it, because imho it doesn't make sense splitting SLD profile for WMS from WMS spec.

Not exactly: I need to get selected sets of features. I can use example three and get some thousand features that correctly show on the map after a looooong time. I need to set a filter, but the filter that worked with the post-request, that I tried first and described in my mail, does not work with the WFS-protocol. So, now I read through all the filter WFS and BBox discussions and still do not know whether it is possible do what I try here: var filter_body = new OpenLayers.Filter.Logical({ type: OpenLayers.Filter.Logical.OR, filters: [ new OpenLayers.Filter.Comparison({ type: OpenLayers.Filter.Comparison.EQUAL_TO, property: "infotext", value: "FS330117000000" }), new OpenLayers.Filter.Comparison({ type: OpenLayers.Filter.Comparison.EQUAL_TO, property: "infotext", value: "FS350067900000" }), new OpenLayers.Filter.Comparison({ type: OpenLayers.Filter.Comparison.EQUAL_TO, property: "infotext", value: "FS350068000000" }) ] }); var DBsellayer = new OpenLayers.Layer.Vector("WFS", { strategies: [new OpenLayers.Strategy.Fixed()], protocol: new OpenLayers.Protocol.WFS({ url: "http://myDomain.com:8090/geoserver/wfs", featureType: "flurst", data: filter_body, featureNS: "http://myDomain.com/demo" }) }); map.addLayer(DBsellayer); I do use Strategy.Fixed because this seems to fix the BBox/Filter-Problem of a WFS-Protocol.

So is there a way to update the markers position instead of removing and creating them? The whole idea is to get rid if marker flickering! the functions are as follow: function addUrl() { newl = new OpenLayers.Layer.Text( "Makinat", {location: "./Views/makinat.php"} ); map.addLayer(newl); } function del() { map.removeLayer(newl); newl.destroy() } I published an example of this at http://212.112.229.168/gpsVer2/ . -------------- next part -------------- An HTML attachment was scrubbed...

This behaviour can be seen e.g. here: http://www.webmapcenter.de/wetterradar/animation.html In that demo the URL of the imagelayer is changed every 500 ms and the flickering should be easy to spot (at least if you wait for roughly 20 seconds). Firebugs Net-tab shows that the images are being requested over and over. The flickering is only noticeable in Firefox (3.5 Win and Linux); Opera 10 and IE 8 work like a charm (they cache the varying images). The changing of the src of a pure with JavaScript does not show the flickering (as can be seen in the above link, too). I don't have results for other browsers. Can anybody help me identify the root of this flickering? I am unsure whether this Firefox bugreport is maybe relevant to this issue: https://bugzilla.mozilla.org/show_bug.cgi?id=492052. I doubt that it is related to apache settings (Caching- or Expires-Headers) as the pure JS solution isn't flickering at all. Any help or advice on this issue would be great! Regards, Marc BTW.: If someone shows me a better alternative to build an animation of different Imagelayers, I would be happy as well :-) From pedropbaracho at gmail.com Wed Nov 18 08:18:31 2009 From: pedropbaracho at gmail.com (Pedro Baracho) Date: Wed Sep 1 17:18:14 2010 Subject: [OpenLayers-Users] Image flickering in Firefox when changing the URL of an image layer In-Reply-To: <4B03F22B.8030208@terrestris.de> References: <4B03F22B.8030208@terrestris.de> Message-ID: <5e3c00490911180518k137596c7o35b08fe772c41f44@mail.gmail.com> For the record, I am currently using FF 3.5.5, Gecko/20091102 on Windows and I don't see any flickering in the link you posted.

We tried to move a marker as shown in the example below but after several zoom-in steps the marker suddenly disappears and reassigns by zooming out. Here the entire code. We merged the two examples marker-shadow.html and draw-feature.html to get there. Does anyone have an idea? OpenLayers: Vector Graphics with Shadows

Marker Shadows using Background Graphics/Z-Indexes

This example shows off marker shadows using background graphics and z-indexes. Move the features around to show the shadows' interaction.

The GetFeature control will set the property features with the features selected during runtime. As I understand it, you should only preset it if you want some features preselected. I think you should do this: control = new OpenLayers.Control.GetFeature(...); map.addControl(control); and replace what you are calling "map.someobject" by "control.features". Is it clear? Or did I mess up? hehe :P Hope you understand... Cheers, Pedro.

Furthermore a wms getfeatureinfo returns some infos when the user is clicking on a point on the map. Thereby the wms getfeatureinfo returns a "application/vnd.ogc.gml". Afterwards i parse my gml and the user gets the parsed info. What I want to add now is, that the user only getting some info, when certain points are clicked (for example: only when point 2 or 3 is clicked). I think this is only possible when i replace my wms getfeatureinfo with a wfs getfeature + a filter. Am I right with this thought? The wfs should also return a gml what I can parse then. I hope someone can help me (maybe with an easy example of a wfs getfeature request + filter) because I have not so much experience with openlayers. Thanks for your answers.

Unfortunately all examples I found have hard coded coordinates for the extend which part of the map to show. My KML file is generated dynamically so I want to zoom the Map to the extent of the layer. The KML file is loaded and shown: kml = new OpenLayers.Layer.GML("KML", "mykml.kml", { format: OpenLayers.Format.KML, formatOptions: { extractAttributes: true, extractStyles: false }, projection: map.displayProjection }); map.addLayer(kml); But when i later try to zoom to the objects included in the KML, the map does not move as expected (yes, the KML has been loaded when I call this): map.zoomToExtent( kml.getExtent() ); The getExtent() method of OpenLayers.Layer does only return the current viewport but not the whole extend. The following does not works neither: map.zoomToExtent( kml.maxExtent ); I think the problem is that the KML layer may lie outside of the current viewport and so it does not get loaded (?) I just want to get the smallest bounding box that contains all coordinates in the KML file. How can you do this? Thanks!

The strategy is as follows: When getURL is called on the browser an ajax request is called to my osm server and the necessary tiles are loaded and stored to the webserver. This works pretty well and I can see tiles lying around on my webserver. But of course this takes some time and is too late for openlayers to render this specific tile in the scope of the getURL method. So there are no tiles visible in the browser which is logical. I now tried to call layername.redraw() in firebug after all tiles where loaded. I see in firebug that all the necessary tiles are again requested within the getURL function. The URLs are alright and the tiles are at the right place. But again nothing is visible in the browser! But now comes the strange thing. When I copy one url string of a tile from the firebug console and open it in a new browser window, the tile (.png) is shown in the browser! And even more strange (at least for me) when I *now* call layername.redraw() this tile is shown in the map. But only this tile and not the others. When I open another tile in a new tab and call redraw() again two tiles are visible and so on. It seems that tiles are visible only when they are requested before.

This behaviour can be seen e.g. here: http://www.webmapcenter.de/wetterradar/animation.html In that demo the URL of the imagelayer is changed every 500 ms and the flickering should be easy to spot (at least if you wait for roughly 20 seconds). Firebugs Net-tab shows that the images are being requested over and over. The flickering is only noticeable in Firefox (3.5 Win and Linux); Opera 10 and IE 8 work like a charm (they cache the varying images). The changing of the src of a pure with JavaScript does not show the flickering (as can be seen in the above link, too). I don't have results for other browsers. Can anybody help me identify the root of this flickering? I am unsure whether this Firefox bugreport is maybe relevant to this issue: https://bugzilla.mozilla.org/show_bug.cgi?id=492052. I doubt that it is related to apache settings (Caching- or Expires-Headers) as the pure JS solution isn't flickering at all. Any help or advice on this issue would be great!

I have 10 WMS layers (polygons) which do not overlap. I'm trying to panZoom to the center of the polygon which user clicked. I registered "featureselected" events on all WMS layers, like this: for(var i in map.layers[layer]) { mapa.events.layers[layer] = new OpenLayers.Control.GetFeature({ protocol: OpenLayers.Protocol.WFS.fromWMSLayer(map.layers[layer],{ geometryName: 'geometry', srsName: "EPSG:900913" }), hover: false }); mapa.events.layers[layer][i].events.register("featureselected", this, function(e) { var objekt = e.feature; var bbox = (objekt.geometry.bounds); var newcenter = (bbox.getCenterLonLat()); mapa.panTo(newcenter); } And this works. Map gets centered to the object that I have clicked. But as I see, there are 10 post request to Geoserver, featureselected is triggered on every WMS layer. Is this not an overhead? Why is event featureselected triggered, even I have clicked outside a layer? 1. Is this normal behavior? 2. What would happen if I have 100 layers? 3. Should I use different approach?

Why is event featureselected > triggered, even I have clicked outside a layer? The featureselected event *isn't* triggered -- that event just centers the map. The event that requests the datai s the GetFeature control. The GetFeature Control has no way of knowing that there is a feature under your cursor without asking the server. What you have downloaded is just images -- OL knows nothing about the geometries. As such, it has to ask the server for each of the layers whether there is an intersecting feature. > 1.

I am trying to connect to a published web service that is configured like GoogleMaps. They have given me instruction of the url philosophy and have explained that the Urls will look very similar to Google's. Instructions were... http://www.nearmap.com/maps/hl=en &x=53843&y=38889&z=16&nml=Vert&s=Ga * The x, y, and z are the image location and zoom level, with the same values used by Google or Bing (ie, standard slippymap tile co-ordinates). * The nml parameter is the NearMap layer, and can be one of: o Vert for PhotoMap 'Vertical' images o N, S, E or W for MultiView images looking North, South, East or West o Map for NearMap StreetMap images o Dem for terrain images * The hl is the Host Language; only English is currently supported * The s parameter is ignored; it can be used as with Google Maps, to work around issues in FireFox's caching The equivalent Google Maps URL would be: http://khm0.google.com/kh/v=48 &x=53843&y=38889&z=16&s=Ga NearMap also support this format; just change the hostname: http://www.nearmap.com/kh/v=48 &x=53843&y=38889&z=16&s=Ga In fact, NearMap have a set of hostnames that match Google's, so the only change needed is to the domain: http://khm0.nearmap.com/kh/v=48 &x=53843&y=38889&z=16&s=Ga These URLs will get the latest NearMap images. To give a specific date, add the nmd parameter, with the date in YYYYMMDD format. For example: http://khm0.nearmap.com/kh/v=48 &x=53843&y=38889&z=16&s=Ga&nmd=20091031 http://khm0.nearmap.com/kh/v=48 &x=53843&y=38889&z=16&s=Ga&nmd=20090926 You should be able to replace google with nearmap in most Google image URLs and get an equivalent image. However, there are some differences: * The recently introduced Google lyrs parameter isn't yet supported. * NearMap doesn't have a layer with terrain data and maps combined, like Google. * The NearMap servers will deduce the type of image from the URL path (/kh or /mt), the Google-compatible v parameter (if supplied) or the nml parameter. The nml parameter overrides the others. To open the NearMap map page with a given location shown, use a URL like: http://www.nearmap.com/?ll=-31.962103,115.832505 &z=15&t=h The same URL can be used with Google: http://maps.google.com/maps?ll=-31.962103,115.832505 &z=15&t=h So I looked in OL lists etc and found the page about TMS. http://trac.openlayers.org/wiki/UsingCustomTiles But I have never done this before and I managed to get the following test app going but with no luck on the nearmaps data layer. http://demos.numaps.com.au/nearmap_test.html It seems to be navigating the tiles correctly but they are all broken (pink). I must be doing something very wrong because if you copy the location (firebug) of the Url into browser it works. http://www.nearmap.com/?x=69 &y=186&z=10&hl=en&nml=Vert&s=Galileo But I also do not really understand why as this is getting a whole map area of tiles and not a single tile? Can anyone who has done this before have a quick look at my code for this example. Its probably very simple I have tried everything I can think of with no luck.

I think the problem might be in the combination of your stylemap and your newly created style for that feature. Btw: isn't there any way you can use a stylemap with rules? If there is a specific attribute in your first feature that differentiates itself from the other(s), then you would not need to use the beforefeaturesadded event at all. > This also fails, with the same result: > > testfeatures = geojson_format.read(results); > testfeatures[0].style = tracks_style; > track_layer.addFeatures(poofeatures); > I assume you meant to say in your last line: track_layer.addFeatures(testfeatures); ?

My goal was to write an application with open source technologies to track cars driving around. I wrote a prototype with geoserver and openlayers and this was succesfull. The big problem was the memory consumption (especially in IE) because of the large amount of DOM manipulation that is done when panning and zooming and drawing vector's (the cars, with fills, stroke, label etc.) Since using a plugin is out of the question here I began investigating the html5 canvas. I know it's not supported in IE, but for me that was a good thing because it gave me the opportunity to have the client choose a different browser then IE. My plans for the future of the app is to also use workers and the browser database (to be able to store historical responses clientside to draw a route the car has followed for the last 10 minutes or so) Also I think the canvas gives us the opportunity to create a print control or a save map as, because in the end it's just an image. (have to combine the layer specific canvasses into one but that's easy ;-)) If you have any other ideas or see different opportunities let me know, my client is fundning me to experiment with html5 so I might be able to spent some time on other's feature requests ;-) Cheers Kris -----Original Message----- From: Eric Lemoine [mailto:eric.lemoine@camptocamp.com] Sent: Thursday, November 19, 2009 6:53 AM To: Kris Geusebroek Cc: OpenLayers Users Subject: Re: [OpenLayers-Users] First try with html5 canvas for layers On Wednesday, November 18, 2009, Kris Geusebroek wrote: > > > > > > > > > > > > > > > Hi All, > > > > I'm currently investigating the > possibilities of integrating html5 functionality into openlayers. > > My first try is using canvas for a layer > instead of div's > > > > I've setup a sandbox which you can > use to have a look: http://dev.openlayers.org/sandbox/krisgeus/openlayers/examples/tilecache Canvas.html > > > > This is the first example to show it's > possible ;-).

May I ask what's your goal with displaying tiles using canvas? Is it performance? I have never played with canvas so I'm interested to know and talk about what it can bring to OpenLayers.

The OpenLayers.Protocol.WFS.fromWSMLayer function doesn't automatically fetch features from the wfs layer, but only in response to a click event. I would like it to automatically fetch (some) features at startup but don't know how. John. ------ -------------- next part -------------- An HTML attachment was scrubbed...

Google Layer Example

Demonstrate use of the various types of Google layers.

For best performance, you must be using a version of the Google Maps API which is v2.93 or higher. In order to use this version of the API, it is best to simply set your application to use the string "v=2" in the request, rather than tying your application to an explicit version.

In order to position the Google attribution div in the default ocation, you must include the extra theme/default/google.css stylesheet.

If you can serve your vector data through something that supports a BBOX filter (i.e. e.g. a WFS or FeatureServer, but not a static file), you can use a BBOX strategy on your vector layer to avoid the issue.

Thanks for you answer Andreas! What does "renderer runs out of coordinate space" really mean? Is there a limitation in OpenLayers/VML or is this a common GIS-"feature"?

The vector data is not a static file, but is created as GeoJSON on the server in my real application, but that's a custom geojson generator, not a WFS or FeatureServer.

If you can serve your vector data through something that supports a BBOX filter (i.e. e.g. a WFS or FeatureServer, but not a static file), you can use a BBOX strategy on your vector layer to avoid the issue.

I would really appreciate help with following tests I am performing. I have set up very basic Open Layers scenario, displaying WMS from Open Layers, Yahoo and Mapnik. My problem is, I can change layers only from Open Layers WMS to Yahoo and back, not to Mapnik, if I do, everything gets broken, I see "South pole" instead of central Europe and the projection is so corrupted I even can not switch back to original Layer. It looks like some OpenStreetMap js bug, because in the following code, if I do have layers order set to map.addLayers([mapnik, wms, yahoo]); - mapnik first, then I see mapnik map ok, but if I switch to Yahoo for example, the projection gets broken, but if I set order to map.addLayers([yahoo, wms, mapnik]); - then I can see yahoo layer, I can change to Open Layers WMS, but when I change to Mapnik, everything is broken again. even more, when I try to display a data imported to postgis from osm and published by geoserver, I can see the data aligned using only Open Layers WMS; if I use Yahoo then the projection is shifted (by 100 km for example), and I have problems using Mapnik at all. Am I doing something wrong ? Thank you for any help. -------------------------------------------------------- OpenLayers: Yahoo Layer

With the canvas implementation how do you support edting of a polygon for instance?

I have a WMS layer providing data over Australia (using tilecache.py) and if I set it up to have no BBOX restriction set on the TileCache, then transparent tiles are requested and provided when my map viewport is showing other parts of the world (e.g. zoomed in on Africa). However, if I set a BBOX restriction on my TileCache and also set the same as a maxExtent on the WMS layer, then I get pink tiles displayed over Africa when I zoom in there, while my actual data tiles display over Australia when it is in the viewport. I was expecting to have no tiles requested when zoomed on Africa with the maxExtent of my WMS set to Australia. Something must be wrong. I've checked my settings a few times now, but being fairly new to OpenLayers I wonder what I might be missing. Can anyone else test this and confirm that this does/doesn't work?

Clifford Dyer) Date: Wed Sep 1 17:18:15 2010 Subject: [OpenLayers-Users] Trouble getting Yahoo layer to line up with mercator coordinates. Message-ID: <1259013241.2924.47.camel@mctell> Hey all, I posted a week or so back about some trouble I was having getting coordinates from a box that users draw. Thanks for all the help with the box drawing code, and pointers to information on Spherical Mercator and other projection issues. I think I'm starting to get a handle on it. It never quite solved my original problem, but I've definitely managed to narrow it down. I'm drawing on a YahooMaps base layer, and the latitude of the box that gets drawn seems not to line up with what I'm actually drawing. Specifically, it seems to show up about 15% of the way between where I draw it and the top of the view window. If I draw at the top of the window, it's accurate; if I draw at the bottom of the window, it's about 15% up the map from the bottom. Longitude renders properly. However, I've noticed that if I switch to a different base layer (I'm working with an ol_wms layer right now), the box moves, and the base layer moves, and everything lines up as it should. So there's something wrong with how I'm using the Yahoo Map. I'm doing this: var yahoo_layer = new OpenLayers.Layer.Yahoo("Yahoo", {}); And all of my layers plus the map show up as EPSG:4326. I had tried defining sphericalMercator: True, but then the map shows up zoomed in on Sao Tome, and won't let me pan away from it. The yahoo layer and the map itself then show up as EPSG:900913, while the vector layer and ol_wms layer show up as EPSG:4326. For what it's worth, I'm getting that information from the following code: alert("Map: " + map.getProjectionObject()); alert("Yahoo: " + yahoo_layer.projection); alert("WMS: " + ol_wms.projection); alert("Vector: " + vector_layer.projection); I'm still missing something in how to get my data into a consistent, usable format. Any ideas?

I'm able to make the request and mapserver returns what seems to be a valid gml, the only problem is that it is not displaying in OL.

I'm probably missing something very simple and stupid ! I have an OL map with google background. The projection is EPSG:900913, so the map unit is meters (right?). I have a marker layer, on which I add a first marker. Then I ask OL to compute a second marker 1 kilometer on the east, and display it. It seems to work, except of my distance problem : if I check with the OL scaleline, there's 1 KM between both markers (which is correct). However, if I use the ruler tool of Google Earth, I can see there is only about 650 meters between these 2 points. Do you have any idea of where my error is ? Thanks in advance, Here is my code : var BeBounds = new OpenLayers.Bounds(2.5, 49.5, 6.5, 51.5); function mapInit() { var map = new OpenLayers.Map('map', { projection: new OpenLayers.Projection("EPSG:900913"), controls: [ new OpenLayers.Control.Navigation(), new OpenLayers.Control.PanZoomBar(), new OpenLayers.Control.LayerSwitcher({'ascending':false}), new OpenLayers.Control.Permalink(), new OpenLayers.Control.ScaleLine(), new OpenLayers.Control.Permalink('permalink'), new OpenLayers.Control.MousePosition(), new OpenLayers.Control.OverviewMap(), new OpenLayers.Control.KeyboardDefaults() ] }); var gsat = new OpenLayers.Layer.Google("Google Hybrid", { type: G_HYBRID_MAP, 'sphericalMercator':true, maxExtent: new OpenLayers.Bounds(-20037508.34,-20037508.34,20037508.34,20037508.34) /*, numZoomLevels: 20*/ }); var markers = new OpenLayers.Layer.Markers("Markers"); map.addLayer(gsat); map.addLayer(markers); // Add a marker var myPoint = new OpenLayers.LonLat(5.080646954,50.49373471); var myPointInMeters = myPoint.transform(new OpenLayers.Projection("EPSG:4326"), map.projection); var pt2 = myPointInMeters.add(1000,0); var mymark = new OpenLayers.Marker(myPointInMeters); var mymark2 = new OpenLayers.Marker(pt2); markers.addMarker(mymark); markers.addMarker(mymark2); map.zoomToExtent(BeBounds.transform(new OpenLayers.Projection("EPSG:4326"), map.projection)); } From dave.potts at pinan.co.uk Wed Nov 25 05:03:08 2009 From: dave.potts at pinan.co.uk (David Potts) Date: Wed Sep 1 17:18:15 2010 Subject: [OpenLayers-Users] loadURL function In-Reply-To: References: Message-ID: <59846.193.123.16.70.1259143388.squirrel@dp2642.force9.co.uk> Quick question about the location of the loadURL function The documentation lists this function as being part of the Ajax package, see http://dev.openlayers.org/releases/OpenLayers-2.8/doc/apidocs/files/OpenLayers/Ajax-js.html#loadURL But if you look at the source code OpenLayers-2.8/lib/OpenLayers/Ajax.js at line 71, the function is declared to be part of the OpenLayers namespace ie OpenLayers.loadURL = function(uri, params, caller, onComplete, onFailure) { Is this an code error or an error in the docmentation?

Although the section is named "loadURL" in the documentation, the signature of the function provided at the beginning of the section makes it clear that it's part of the OpenLayers namespace.

This is only recommended if you have very few features. The prerequisite is to load the layer as vector layer, not from WMS. But back to the original problem.

It is also open-source (not entirely because it has some components under proprietary licensing). I find it very useful and you can try out things and preview your app without leaving the IDE. I think it was built upon eclipse (almost sure) and so the GUI is quite similar. It also has the possibility to include external libraries (like extjs or jquery) and take advantage of autocompleting capabilities.

Most important thing to have in your mind: Browser limit says don't load more then (having IE in mind) -> 100-150 features! Off course we would like to have the highest level of interactivity, that is, to have all the features loaded - vector layer, so we can have fast hover/click effects on features. But because of browser limits that's not possible. So depending on your data, we can cope with this with different solutions: 1) Use wms layer with GetFeature control http://openlayers.org/dev/examples/getfeature-wfs.html Like this all the feature show up, but you only get some info when you click on it. Bad thing is that sometimes it takes some time to query the features (lower interactivity), so make sure you have fast response from your server for this (spatial index data usually helps ;) Use this for large scales of you layer 2) Use vector layers. Use this solutions when you are sure that you wont be requesting lots of features at once (browser limits). Using BBOX with Cluster strategy is not a bad solution. Use this for small scales (small areas -> less features are requested) One important note here: Cluster strategy that we have here is a client solution, that means all the data has to be received before they are clustered. Example: we have 5000 points. If we use cluster strategy they will be visualized with, lets say, 100 points -> within browser limits right? But what about the data transfer and expensive calculations of clusters (every time we zoom in?) Conclusion: be careful with cluster strategy, don't use it if you have more then few hundreds features (and use it together with BBOX strategy) 3) Develop server clustering - this should be the best solution I think (most intereactive also) Let server process the data, and make clusters for you, with some basic cluster info - like geometry, number of features in cluster etc. Then you make vector layer out of it, and implement lets say hover effect that get basic data, and on click you make GetFeatureInfo request that gets the rest of the data. The best example that works in similar way is maps.google.com with Wikipedia & Photos layers, where you can see tons of images at once without lots of stress on thebrowser. Its wms layer with clusters in background, and div elements (or image map?, im not sure) in front.

EPSG:900913 is not a length-preserving projection. As you can see that the equator have the same lenght as the north or south pole! With the OpenLayers measure control you can get probably the correct length. Arnd -----Urspr?ngliche Nachricht----- Von: users-bounces@openlayers.org [mailto:users-bounces@openlayers.org] Im Auftrag von Nicolas Noe Gesendet: Mittwoch, 25. November 2009 12:01 An: users@openlayers.org Betreff: [OpenLayers-Users] Distance problem Hi everyone, I have a simple problem, bit I can't figure it. I'm probably missing something very simple and stupid ! I have an OL map with google background. The projection is EPSG:900913, so the map unit is meters (right?). I have a marker layer, on which I add a first marker. Then I ask OL to compute a second marker 1 kilometer on the east, and display it. It seems to work, except of my distance problem : if I check with the OL scaleline, there's 1 KM between both markers (which is correct). However, if I use the ruler tool of Google Earth, I can see there is only about 650 meters between these 2 points. Do you have any idea of where my error is ? Thanks in advance, Here is my code : var BeBounds = new OpenLayers.Bounds(2.5, 49.5, 6.5, 51.5); function mapInit() { var map = new OpenLayers.Map('map', { projection: new OpenLayers.Projection("EPSG:900913"), controls: [ new OpenLayers.Control.Navigation(), new OpenLayers.Control.PanZoomBar(), new OpenLayers.Control.LayerSwitcher({'ascending':false}), new OpenLayers.Control.Permalink(), new OpenLayers.Control.ScaleLine(), new OpenLayers.Control.Permalink('permalink'), new OpenLayers.Control.MousePosition(), new OpenLayers.Control.OverviewMap(), new OpenLayers.Control.KeyboardDefaults() ] }); var gsat = new OpenLayers.Layer.Google("Google Hybrid", { type: G_HYBRID_MAP, 'sphericalMercator':true, maxExtent: new OpenLayers.Bounds(-20037508.34,-20037508.34,20037508.34,20037508.34) /*, numZoomLevels: 20*/ }); var markers = new OpenLayers.Layer.Markers("Markers"); map.addLayer(gsat); map.addLayer(markers); // Add a marker var myPoint = new OpenLayers.LonLat(5.080646954,50.49373471); var myPointInMeters = myPoint.transform(new OpenLayers.Projection("EPSG:4326"), map.projection); var pt2 = myPointInMeters.add(1000,0); var mymark = new OpenLayers.Marker(myPointInMeters); var mymark2 = new OpenLayers.Marker(pt2); markers.addMarker(mymark); markers.addMarker(mymark2); map.zoomToExtent(BeBounds.transform(new OpenLayers.Projection("EPSG:4326"), map.projection)); } _______________________________________________ Users mailing list Users@openlayers.org http://openlayers.org/mailman/listinfo/users From m.sirin07 at googlemail.com Wed Nov 25 21:08:10 2009 From: m.sirin07 at googlemail.com (Mehmet Sirin) Date: Wed Sep 1 17:18:16 2010 Subject: [OpenLayers-Users] Remove Features By Id Message-ID: <55744b1c0911251808i7d6b60fdpfccd6fe0651d61a6@mail.gmail.com> Hi, I'm failing when trying to remove a feature selected by its ID: ... var startpoint= new OpenLayers.Feature.Vector(point,null,start_style); startpoint.id="hey"; mylayer.addFeatures([startpoint]); ... var something=getFeatureById("hey"); //works mylayer.removeFeatures(mylayer.features[something]); Maybe it's in general not possible choosing a feature by an associative key ?

It should go in layer options like you put it. Then strategy should take that filter and apply it to the protocol when data is requested. But I dont see any filter options inside Fixed strategy, only in BBOX strategy. New ticket? So setting filter manually inside protocol will maybe do the trick.

November 2009 12:01 An: users@openlayers.org Betreff: [OpenLayers-Users] Distance problem Hi everyone, I have a simple problem, bit I can't figure it. I'm probably missing something very simple and stupid ! I have an OL map with google background. The projection is EPSG:900913, so the map unit is meters (right?). I have a marker layer, on which I add a first marker. Then I ask OL to compute a second marker 1 kilometer on the east, and display it. It seems to work, except of my distance problem : if I check with the OL scaleline, there's 1 KM between both markers (which is correct). However, if I use the ruler tool of Google Earth, I can see there is only about 650 meters between these 2 points. Do you have any idea of where my error is ? Thanks in advance, Here is my code : var BeBounds = new OpenLayers.Bounds(2.5, 49.5, 6.5, 51.5); function mapInit() { var map = new OpenLayers.Map('map', { projection: new OpenLayers.Projection("EPSG:900913"), controls: [ new OpenLayers.Control.Navigation(), new OpenLayers.Control.PanZoomBar(), new OpenLayers.Control.LayerSwitcher({'ascending':false}), new OpenLayers.Control.Permalink(), new OpenLayers.Control.ScaleLine(), new OpenLayers.Control.Permalink('permalink'), new OpenLayers.Control.MousePosition(), new OpenLayers.Control.OverviewMap(), new OpenLayers.Control.KeyboardDefaults() ] }); var gsat = new OpenLayers.Layer.Google("Google Hybrid", { type: G_HYBRID_MAP, 'sphericalMercator':true, maxExtent: new OpenLayers.Bounds(-20037508.34,-20037508.34,20037508.34,20037508.34) /*, numZoomLevels: 20*/ }); var markers = new OpenLayers.Layer.Markers("Markers"); map.addLayer(gsat); map.addLayer(markers); // Add a marker var myPoint = new OpenLayers.LonLat(5.080646954,50.49373471); var myPointInMeters = myPoint.transform(new OpenLayers.Projection("EPSG:4326"), map.projection); var pt2 = myPointInMeters.add(1000,0); var mymark = new OpenLayers.Marker(myPointInMeters); var mymark2 = new OpenLayers.Marker(pt2); markers.addMarker(mymark); markers.addMarker(mymark2); map.zoomToExtent(BeBounds.transform(new OpenLayers.Projection("EPSG:4326"), map.projection)); } _______________________________________________ Users mailing list Users@openlayers.org http://openlayers.org/mailman/listinfo/users _______________________________________________ Users mailing list Users@openlayers.org http://openlayers.org/mailman/listinfo/users -------------- next part -------------- An HTML attachment was scrubbed...

I have a protocol wfs which shows some points on my map (with geoserver). That is working fine so far. But besides the points, I want to show the name of the points in my map. Before I used the wfs I had a wms with a sld_body. With this sld_body I could see the points and the names of the points on my map (sld_body= styled layer descriptor with point_symbolizer and text_symbolizer). But because of the big amount of data I decided to use a wfs instead of a wms. Everything works fine with a wfs, but it would be perfect, when I could see the names of the points (besides the points) in my map (like it was with the wms). Is this possible with using a wfs. I have already implemented a styleMap to show my points in different colors. Can I add something like a text_symbolizer there? I hope someone can help me. Thanks for the answers.

It is like there is a spinning loop somewhere. For me this is like the tiles are displayed synchronously : It is looks like the map is not rendered until all tiles are retreived from the network. Inside FireBug, clear() method is eating time and CPU (i'm not used to firebug for profiling) clear()7025.62%73.726ms*3316.139*ms47.373ms40.459ms97.064msOpenLayers.js (ligne 886) The CPU used during zoom is so high that the user experience is not good... i'm available to test any patch to test/investigate the situation.

I have to render a map with the screen resolution of about 4500x3100 (on a wall of screens). It works ok with WFS layers, OSM and even Microsoft Virtual Earth, but I have issues with Google and Yahoo. When I switch to the google layer, the background turns gray and then the browser starts loading the images. After about 130s of loading (there are quite a lot of pictures), I notice that google starts throwing back HTTP 403 errors (Resource temporary unavailable). Just before seeing these errors, some images (the center part of the map) start appearing, but only about 1/4 of the map is drawn. If I wait about 5 minutes, the download process gives up (it still receives HTTP 403 errors all this time), but it displays the rest of the images - which were apparently downloaded before the 403 error appeard. I'm thinking it manages to download most of the visible images + some images in the bbox (which is quite large), but not all the images before getting errors. The problem is the Google API doesn't display what it downloaded, but waits for more images to be downloaded. After analysing the data, I noticed that when the first DNS query is done for the Google cache, it receives back 4 IP addresses. However, only the first 2 IPs are used for traffic - and these 2 IPs start sending back HTTP 403 errors after a while. I would like to know if the following are possible: 1. configure the Google API to use all the IP addresses it receives in the DNS query - maybe this avoids the 403 erros 2. configure the Google API to display the pictures received without waiting for more pictures to download. I'm not sure if this is possible - maybe the images are pipelined through the same connection - and they are shown only when the connection closes. 3. reduce the bbox for the Google Layer - this should be fine for my needs - and maybe avoids the 403 errors. With regard to the Yahoo layer - things are better. It loads faster for the same size (they don't seem to have a "throttling" mechanism), but it only displays the final image when all the bits are downloaded - so it's as fast as the slowest image. Can this behavoir be changed from within OpenLayers?

How is drawn a WFS Layer or a WFS Vector? I mean, with WMS, the client gets images and no more processing is needed.. But how (where?) Openlayer.js read/parse the gml information that serves WFS? The vector layer is configured with a WFS protocol, which is configured with a WFS format, which relies on a GML format for parsing geometries received in GetFeature responses. Features resulting from parsing GetFeature responses are added to the vector layer, and then rendered in the page using SVG, VML or Canvas. > If I want to draw some points programatically, what is the best way? Just create OpenLayers.Feature.Vector objects and add them to an OpenLayers.Layer.Vector layer. I'd recommend searching the OpenLayers examples.

But you can inherit from LayerSwitcher and overload the maximizeControl method: CustomLayerSwitcher = OpenLayers.Class(OpenLayers.Control.LayerSwitcher, { maximizeControl: function() { OpenLayers.Control.LayerSwitcher.prototype.maximizeControl.apply(this, arguments); // do what you need here } }); note, though, that maximizeControl isn't part of the public API, so this code could break with future OpenLayers releases.

Using OpenLayers.Layer.Google is nothing else than using a GMaps Map directly, you just access it wrapped by an OpenLayers layer type, not by the API directly. I also do not see a violation of the terms of use. We even make sure that the Terms of Use link is clickable if we render other layers on top of Google. There is, however, a known issue: if you create your map at a smaller size and switch from one Google Layer type to another after resizing it to your big map, tiles will only be loaded for the area of the old extent. There is a patch that appears to solve this issue.

No idea if you can do that there. For WMS layers, if using tiles, you can set the buffer option to 0. If untiled, set the ratio option to 1. Regards, Andreas.

Message-ID: <5e3c00490911300953i11b11666we2a8290fe50d9802@mail.gmail.com> In some part of my code I am sending multiple requests asynchronously to some servers. The problem is: I need some information from the requests (like server address and URL string) in order to process the responses and these informations aren't available in the response parameter (which is something like a GML). That being said, I think the best way is to preset some parameters in the callback function when sending the requests. I found this solution: http://openlayers.org/pipermail/users/2009-March/010890.html which partially explains OpenLayers.Function.bind() and gives another option of using the scope to set the parameter. The problem with these solutions is that I need the scope to be on the current object AND set additional parameters. In other words, I CAN'T change the scope, which means either I set these parameters inside the scope in some sort of twisted temporary variables or I use some unknown method which allows me to tell OpenLayers: "When calling the callback function, set these parameters additionally to the response". This is what I have: for (i in servers) { OpenLayers.Request.issue({ url: servers[i], headers: {...}, params: {...} success: this.someFunction, scope: this }); } This is what I need: for (i in servers) { OpenLayers.Request.issue({ url: servers[i], headers: {...}, params: {...} success: this.someFunction(i, response), // preset parameter "i" scope: this }); } Is OpenLayers.Function.bind() what I am looking for? If it is, how do I use it? I didn't find any docs on it, on OL API. Thanks in advance. -------------- next part -------------- An HTML attachment was scrubbed...
