I am using OL 2.4. I have an application with a baselayer of tiled WMS served by tilecache. On top are a few WMS overlays. In Internet Explorer sometimes the lower rim of the application does not load the tiles. If I pan something like 50px up they will appear. The pattern is repetitive when panning towards the north. Firefox does not have this problem. It is always the lower part which won't load. See: IE: http://www.osgis.nl/download/geotool_ie.jpg versus Firefox: http://www.osgis.nl/download/geotool_ff.jpg Any ideas appreciated. Thanks in advance.

The extents specified in your .map file contain points in Argentina. The meat of the issue seems to be the lon and lat parameters passed into the map.setCenter method. Try something like: //------------------------------------------- lon = -64.187587; lat = -31.437243; zoom = 5; map.setCenter( new OpenLayers.LonLat( lon, lat ), zoom ); //------------------------------------------- This will, at the very least, center your map on an area that contains valid data (based on your .map file).

In the cases that paint something, the behaviour is: 1) It paints the features but only when i press double click (at the time i am drawing it doesn't paint anything), in big scales. 2) In small scale the behaviour is different, it shows me the features at the same time i am drawing but when i do a double click it doesn't paint anything. what i am doing wrong? thanks very much.

Today I was setting the visibility of a layer using the setVisibility call and noticed some incorrect behaviour under safari 2 and 3. I then went to the openlayers.org home page and started fiddling with the Canada transparent layer and noticed the same issue. To reproduce you need to switch on the Canada layer, switch it off then try and switch it on again (without scrolling). You should notice that it does not appear again. If you scroll or zoom around you'll find it can come back. By scrolling around you can get the situation where you have some of the transparent tiles visible and some missing. Can someone please confirm they can reproduce this one before I file a bug report? -------------- next part -------------- An HTML attachment was scrubbed...

My map is 694x464 pixels. Tilesize is 256. Buffer is 1. Initially, a grid of 6x4 tiles is created. When zooming in to the zoom level which has this problem, only 6x3 tiles are created (so one of the rows is removed from the grid). It can be quickly patched in the _initTiles function: _initTiles:function() { // work out mininum number of rows and columns; this is the number of // tiles required to cover the viewport plus one for panning var viewSize = this.map.getSize(); var minRows = Math.ceil(viewSize.h/this.tileSize.h) + 1; var minCols = Math.ceil(viewSize.w/this.tileSize.w) + 1; by replacing + 1 with + 2*this.buffer. Maybe/hopefully :-) someone more knowledgeable of this part of the code can determine the right fix for this.

First I find Openlayers/Tilecache looks like great pieces of software, BUT what's great software without proper documentation ... and that's what both are missing for sure. I've made some maps for a game and want to share them with others on the web, so I've searched the web and ended up at Openlayers Website (if there's something better to do what I want, please tell me!). My Map is atm a huge Image file and I want to do something like http://tilecache.org/demos/xkcd-onlinecommunities.html or http://tilecache.org/demos/mario.html But I didn't find any documentation that told me how to do that. Can Tilecache cut my Image into tiles? How do I configure that (ImageLayer was mentioned in another mail but from the code I think I got that that's what I'm searching but no word on how to configure)? Can the people who did the demos please not only show the results, show how you've done that! I'm also thinking about cutting my map into tile via a script myself (think this http://wiki.osgeo.org/index.php/Image:Tms.png is how they are named?) and simply put it on the right places (directories), but how do I configure Openlayers to use them because it's no WMS or whatever service then ... Can you help me with some links/docs/howtos/words please?

I'm experiencing problems with handling the features of a GML layer, which is loaded when the page is opened. The problem is that after the 'loanend' event is raised, the features-property of the layer stays empty for some more time, so there is no way to examine the features in this handler. In my case I need to extract the bounds-properties of the features to construct an common bounds-object for zooming (the action should simulate feature selection and zooming to the selection). Any ideas, how this could work? Here's my code snapshot: function SelectFeature() { var layer = GetLayerByName(FEATURE_LAYER); //returns a MapServer layer to send a request on if (layer == null) return; var selection_url = CreateWFSGetFeatureRequest(layer, FIELD_NAME, FIELD_VALUE); //creates a WFS GetFeature-request if ((selection != null)&&(selection.map != null)) { OLMap.removeLayer(selection); selection = null; } selection = new OpenLayers.Layer.GML("Selected Objects", selection_url); OLMap.addLayer(selection); selection.displayInLayerChooser = false; selection.events.register("loadend", selection, ZoomToSelection); selection.events.triggerEvent("loadend"); } function ZoomToSelection() { var bounds = ComputeSelectionBounds(); if (bounds == null) return; OLMap.zoomToExtent(bounds); } Thanks in advance! -- Regards, Dmitri -------------- next part -------------- An HTML attachment was scrubbed...

I am also seeing similar issue with Google as the base layer. While dragging the map, WFS layer seem to smoothly drag but the underlying the Google turns white before coming alive, thus resulting in flickr. I am assuming that this is related to some kind of interaction between the openlayers & google tile cacheing. Has anybody seen the issue?

I haven't got any reaction to my previous mail, so I'm trying to point your attention to my problem again in this follow-up. The problem is: after loading a GML layer the features collection of the layer stays empty (at least for some time), which means that there's no way to handle those in the loadend-event of the layer. Is there another event, which is raised after the features collection of the loaded layer is initialized? Is there any rational workaround? My next action would be setting up a timer with the setTimeout(...) function and trying to access the features collection after some time interval hoping that the features are finally loaded. However, this seems to be a very hardcoded solution. Cheers, Dmitri Mizerkin ---------- Forwarded message ---------- From: Dmitri Mizerkin Date: 05.07.2007 10:33 Subject: Problem with GML features To: users@openlayers.org Hello everybody! I'm experiencing problems with handling the features of a GML layer, which is loaded when the page is opened. The problem is that after the 'loanend' event is raised, the features-property of the layer stays empty for some more time, so there is no way to examine the features in this handler. In my case I need to extract the bounds-properties of the features to construct an common bounds-object for zooming (the action should simulate feature selection and zooming to the selection). Any ideas, how this could work? Here's my code snapshot: function SelectFeature() { var layer = GetLayerByName(FEATURE_LAYER); //returns a MapServer layer to send a request on if (layer == null) return; var selection_url = CreateWFSGetFeatureRequest(layer, FIELD_NAME, FIELD_VALUE); //creates a WFS GetFeature-request if ((selection != null)&&(selection.map != null)) { OLMap.removeLayer (selection); selection = null; } selection = new OpenLayers.Layer.GML("Selected Objects", selection_url); OLMap.addLayer(selection); selection.displayInLayerChooser = false; selection.events.register ("loadend", selection, ZoomToSelection); selection.events.triggerEvent("loadend"); } function ZoomToSelection() { var bounds = ComputeSelectionBounds(); if (bounds == null) return; OLMap.zoomToExtent(bounds); } Thanks in advance! -- Regards, Dmitri -- Gru?, Dmitri -------------- next part -------------- An HTML attachment was scrubbed...

Can you send me a link? Thanks to az2a on IRC and some reading of the code, lead to this solution: map.events.register('moveend', map, function() { map2.setCenter(this.getExtent().getCenterLonLat(), this.getZoomForResolution(map.getResolution())); }); map.events.register('zoomend', map, function() { map2.setCenter(this.getExtent().getCenterLonLat(), this.getZoomForResolution(map.getResolution())); }); I created map and map2 objects, with map having all the nav controls and map2 being a slave that is synced to map. -Steve From tchule at hotmail.com Fri Jul 6 09:49:12 2007 From: tchule at hotmail.com (Benoit PESTY) Date: Wed Sep 1 17:15:35 2010 Subject: [OpenLayers-Users] Z-index ordering in Layer Switcher Message-ID: Hello, For an application I'm working on I need to offer the possibility for the user to choose the Z-index ordering of the layers he is using. I've seen something like this in the WMSManager component but as I wanted something simpler I've modified the Layer Switcher component. The source code of my layer switcher is in attachment, in case someone else is interested. It seems to work in my environment (I've not done extensive tests), if you see things that could be done in a better way don't hesitate to tell me. For this application I will maybe have to do some other changes on my version of OpenLayers (based on 2.4 but with some custom Javascript and PHP to link my data to a PostGis database), I'll try to publish things I can publish.

Message-ID: <76758090F8686C47A44B6FF52514A1D307909D7D@hermes.uai.int> Steve, I would attach an event handler to the moveend or zoomend event off of your master map, and move the slave to match. This assumes that both are in the same projection of course :-) Something like: // assuming that your main map is in "var master" master.events.register('moveend', master, mapMoveEnd); and then have a funcitno mapMoveEnd that did a slave.setCenter based off of the new values in master (master.getCenter() and master.getZoom()). We have something similar for setting up the map in the print preview page on our hud site.

There is no good way to do what you want right now. I assume you're talking about the WFS layer in vector mode (as opposed to marker mode). When the tile for this layer is drawn a WFS request is made asynchronously - when this request returns, the GML is parsed and added to your layer. As each feature is added to your layer, the optional onFeatureInsert property of your layer (a function) is called. This is not handy if you want to know when the features are done being added. I thought there was a ticket out there already for this. I'll check - and add one if not. I'm hoping to do some work on the WFS layer in the near future. This and other issues will likely get addressed then.

I can use OpenLayers with WMS layers from the GeoServer (war install) with out any problem. The issue occurs when trying to use a WFS layer like below. wfs = new OpenLayers.Layer.WFS("WFS fixpoint", "http://172.16.135.144:8080/geoserver/wfs?", {typename: "topp:fixpoint" ,maxfeatures: "100"}, {featureClass: OpenLayers.Feature.WFS} ); This layers in not drawn on the map, but causes no errors. After seaching around on the net and forums i have discovered that i must set the OpenLayers.ProxyHost to get the WFS layer to be displayed, and have seen many examples such as this: OpenLayers.ProxyHost="/proxy/?url="; The above will not work for me, how can i set the proxy host within JBoss. The page i am using openlayers on is a .jsp (using jsf), packed inside a simple .war archive. Has anybody managed to set up the ProxyHost under JBoss before ? Is it just a matter of packing something (python script ??) into my war archive ? Any advice would be greatly appreciated .

Hi Fadi What version of OpenLayers are you using? There was a bug () that got fixed in 2.4 RC4. If you're using the current stable release (2.4) you should not see this bug. If you're on the stable release and yet see the bug, report the problem here again and we'll look into it...

When images don't load, they don't load because the browser decided not to load them -- I have no idea why this happens. The IMAGE_RELOAD_ATTEMPTS is the only way I know of to fix this, and I have no idea why this wouldn't work.

The best thing for you to do is probably to get the OpenLayers file served from within GeoServer. So, your OpenLayers HTML should be at http://172.16.135.144:8080/openlayers/ or whatever. Once you do that, you don't need a proxyhost anymore. Anything else is going to be vastly more complex.

No sweat, but I do have some other applications for such functionality. Does there exist a method that orders OpenLayers to refresh the current map view, re-download all tiles for the current viewport, or for a specific layer? A real-world use comes to mind when using dynamic data, e.g. having added a new point to a database via some PHP script, I'd like to redraw the WMS layer without my reloading the entire page and losing my place. I don't see documentation of a .redraw() method, for example, on the Layer or Map objects, so I take it the answer is No here? -- Gregor Mosheh / Greg Allensworth System Administrator, HostGIS cartographic development & hosting services http://www.HostGIS.com/ "Remember that no one cares if you can back up, only if you can restore." - AMANDA From gstamp at gmail.com Mon Jul 9 03:08:20 2007 From: gstamp at gmail.com (Glen Stampoultzis) Date: Wed Sep 1 17:15:35 2010 Subject: [OpenLayers-Users] Flicker while dragging map with vector in FF In-Reply-To: References: <468CAE6F.2040100@gmail.com> Message-ID: On 06/07/07, bradleyspencer wrote: > > Louvy, > > I have the same problem I think.

Sorry for the lateness of my reply. I only just noticed your message. The issue was being caused for me because I was was erasing and redrawing a vector when any pan occurred. This would cause black triangles to appear for me when it was erased. This was fixed in FF by moving the erase into the same event as the draw. Previously I was erasing the vector making an ajax request then drawing a new vector. Unfortunately this causes a weird ghost line in Internet Explorer for a split second so I had to keep the erase before the ajax request in Internet Explorer. this means the line disappears until the ajax request comes back which is unfortunate. The flicker I was experiencing doesn't seem to be the same thing that I'm seeing on your site. -------------- next part -------------- An HTML attachment was scrubbed...

If you are using trunk, there is now a function "redraw()" on Layer that should work to redraw layers, but there is not a map.redraw(). What you would do is call map.setCenter() and passing "true" for the "zoomChanged" flag.

Nice; thanks for the tip and the trick.

Is this possible ? Note that the WFS layer takes 4 arguments[1]. You are including the "SLD" and "extractAttributes" properties in the third argument above. These get mapped to parameter names in the GetFeature request. The "extractAttributes" property belongs in the options argument (the fourth). This tells OpenLayers to extract all attributes of the returned features. It doesn't mean anything as a parameter in the GetFeature request. Putting the "SLD" parameter in the third argument makes it one of the named parameters in your GetFeature query string. For WMS, you can do this - make a GetMap request with a URL to an SLD doc. The WFS spec does not say what to do with an SLD parameter in the GetFeature request. This means that the way you've set things up above, you shouldn't expect anything to happen. If you did mean to include the SLD property in the options argument, as Chis mentions, this also currently means nothing to OpenLayers. This could change in the future.

The reason for this is because of zoom levels. The way initResolutions() works is that it takes all the information that has been provided (as options to the layer or options to the map) and tries to create a resolutions array. Since you specify min&max Scale, what it does is first to convert those two values into the corresponding resolution values (maxResolution/minResolution). Then, in order to create the resolutions array, it executes the following code: // determine numZoomLevels if (confProps.minResolution != null) { var ratio = confProps.maxResolution / confProps.minResolution; confProps.numZoomLevels = Math.floor(Math.log(ratio) / Math.log(2)) + 1; } Basically, unless you explicitly specify a resolutions or scales array, OpenLayers works on a power of two principle (like google, yahoo, others) for determining the zoom levels. Thus it will start from the maxResolution and progressively build up from there. In order to determine when to stop, it takes a ratio between the min and the max and uses that to set numZoomLevels. Hopefully that makes sense. If you want to be precise about your max and min scale values, the best thing to do would be to specify a scales array with all the intermediate levels you wish to display in between min and max. If someone has an alternative way of programmatically defining those intermediate steps betweeen min and max scale/resolution, please write in to the list with some suggestions -- we're certainly open to hearing them... this power of two bit is just a default that has worked well in general.

She's actually doing much better today, and we'll hopefully be taking time off in another couple weeks to get the trip up to the mountains we had planned. > And, I'm sure this is echoed by everybody, thank you so much for all the > effort you put in to development and support of OpenLayers. Thanks again. The biggest benefit to helping the OpenLayers community is the true appreciation that is offered by the community in so many ways -- whether it be email, IRC, IM, or just in using the code. THe growth of this community over the past year has been tremendous, and I can't say enough how great it is to be a part of it.

It really depends on what you mean by security. It's quite tricky to do this on the client given the very nature of what openlayers does (ie makes asynchronous requests to open web servers), so most security (eg limiting requests by IP address, limiting which layers can be viewed by clients is handled on the server side.

I think Christopher was concerned that the marker layer was not picking up the valid zoom levels from the base layer by default. I tend to think that the markers, given no other parameters, should be visible at all zoom levels valid for the base layers.

On the other hand, this wouldn't solve the problem for OpenLayers.Layer.WMS.Untiled which inherits OpenLayers.Layer.HTTPRequest but not OpenLayers.Layer.Grid.

Do you > have any plans for layers that don't inherit OpenLayers.Layer.Grid ? :-) So the good news is that the essential part of the patch that I'm working on is to bring the Gridded and Untiled layers back together. Instead of declaring your layer as OpenLayers.WMS.Untiled, you will simply declare it OpenLayers.WMS and pass it an option { singleTile: true } Thus, both of those will be supported. :-) Erik > > > Keep an eye out for it, > > I will. > > PS: sorry Erik for the direct mail.

So while somebody is drawing a (sometimes rather large) linestring and does ctrl-Z or something like that, I want to grab the current linestring being edited, remove the last added point and draw the (one point shorter) linestring again. I thought this would be easy, but it isn't ( for me :-( ). The Vector layer doesn't have the feature/geometry in it's hands while you are drawing it, and the point-callback get's a 'Point' as argument (instead of the Linestring?). Have been looking into the source of the DrawFeature control and Path Handler, but couldn't find a hook. Somebody an idea for implementing this?

Does that make sense, Trond? If you set the buffer to 0, then OL wont pre-load any tiles that are outside the bounds of the viewport of the map.... therefore, if you set a tile size that is bigger than the viewport, you will always only be loading one tile... and since you're still in normal gridded mode, you will be snapping to grid and benefit from cacheing.

Yes, Josh is right. you will have border cases, in which case this isnt very useful. If you want cached tiles, however... you will always have this gridded case.

When I didn't see the example online, I started fresh on this. Turns out it's quite different than the one that you put together. I needed different sorts of configuration options. So, for my version of regular polygon drawing (and approximating circles), see http://dev.openlayers.org/sandbox/tschaub/feature/examples/regular-polygons.html Thanks for the inspiration, Tim (Note that this requires a few patches that aren't in the trunk yet.)

You should be looking at OpenLayers.Feature.Vector. A point geometry doesn't have direction. A feature is geometry plus attributes. If you create a feature with a point geometry, you can store any arbitrary attributes along with it. Hope that makes sense.

In-Reply-To: References: Message-ID: - About this " orientation of points " discussion thread: I do believe that any " Geometry " or " Feature " can possibly be attributed an orientation, not only Points. A LineString, a Polygon, even a MultiPolygon may be characterized by a " general orientation ". Actually, a good approximation of any spatial object could be an ellipse (the kind of potato we can sketch on a map) for which we need a LatLon plus two floats. Let's name Potatoid this ellipse. Hence, I would be interested by a more general solution, and I have a suggestion : Tim proposes to use OpenLayers.Feature.Vector that associates external attributes to a Geometry, it is one point ; the second point is that there is a method Geometry.atPoint(lonlat, toleranceLon, toleranceLat) that positions approximately the Geometry, it is - as I understand - simply the center of the bounding box hence, for a Point, it should be the Point itself (I didn't check) but the other two parameters can be used to determine the orientation, and for Point, they are certanly zero (I didn't check) therefore, the Potatoid, or ellipse, or oriented point, etc. can be set and drawn from the answer of Geometry.atPoint(lonlat, tlon, tlat) or OpenLayers.Feature.Vector.Geometry.atPoint(lonlat, tlon, tlat) The problem is : how to set these (lonlat, tlon, tlat) differently that from the bounding box ? my suggestion is that the method atPoint should exist also at the Vector level, and: - to add methods : Vector.setPoint(latlon) Vector.setOrientation( tlon, tlat) e.g.: sinAlpha, cosAlpha in case we want to explicitely set the Potatoid It can be set in the Vector.attributes object, but we need a special flag to inform the atPoint() method to behave differently in this case : - Vector.Geometry.atPoint() is exactly Geometry.atPoint() if the flag is false - Vector.Geometry.atPoint() returns (lonlat, tlon, tlat) computed from the Vector.attributes, considered as the Potatoid, if the flag is true That it makes sense ?

Then I want to be able to select a specific marker clicking on it, so I've registered the click event for OpenLayers.Marker; then, when the event is raised I can react on the selection of that specific marker and present for instance information about the selected marker to the user. The problem comes when I have markers at the exact same location; then, no matter how much I zoom in, they all appear as one single icon and so I can only select the one on top. I have been thinking in offering for instance the possibility of right-clicking on a marker and getting a list of markers at the same location, if any, but that seems to me a bit tedious thing to do, since I would have to search the location of all the markers on all the layers and compare them to find which ones are at that (or very close to that) location. So my question is, is there an easy way of selecting any of the markers located at a same location? Do you have any suggestion of making markers at the same location easily "selectable"?

This also might be handy to add to the OL FAQ.

Does OL get wrong images from the mapserver? > Or is the grid from the mapserver images setup wrong? Each request to a WMS for an image tile is independent. When you you request a tile from MapServer with bounds that contain your train station (point), MapServer will render as much of that symbol as it can on that tile. When you request the next tile that doesn't contain the train station (point), MapServer has no reason to render a partial train station. You can get around this in two ways: 1) use something that requests larger tiles with a buffer, slices them up in to smaller tiles and discards the buffer - see http://tilecache.org or 2) use the "gutter" property on your WMS layer in OpenLayers - see http://dev.openlayers.org/docs/files/OpenLayers/Layer-js.html#OpenLayers.Layer.gutter # ignore a 10 pixel gutter around each tile var layer = new OpenLayers.Layer.WMS(name, url, params, {gutter: 10}); Good luck, Tim > > Are there settings in OpenLayers for this? > Thank you. > > > ------------------------------------------------------------------------ > > _______________________________________________ > Users mailing list > Users@openlayers.org > http://openlayers.org/mailman/listinfo/users From tben at refractions.net Thu Jul 12 17:20:19 2007 From: tben at refractions.net (Thomas Bengtson) Date: Wed Sep 1 17:15:37 2010 Subject: [OpenLayers-Users] How to switch between panning / zooming mode for dragging events?

There was a post to the Google Maps API Google Group on Jun 5 by Josh Livni (http://groups.google.com/group/Google-Maps-API/browse_thread/thread/3cab18706cb51efd?hl=en) demonstrating this behavior with the Google Maps API alone, with no responses from that group. Is there a solution that has been proposed which hasn't been accepted? I hope not, since this bugs me very much as well, and I'd love to have it fixed - I just don't have any way to do anything about it that I'm aware of. If you have a patch or other contribution, and it hasn't made it to trac yet, please do feel free to describe it in prose or code in the ticket -- http://trac.openlayers.org/wiki/FilingTickets has login information, if that's a blocker.

I work for the government of Canada on a project to develop visualization tools. I tried to adapt the example from http://www.openlayers.org/dev/examples/getfeatureinfo.html To get the getfeatureInfo working. I get the loading message in the div section 'nodeList'. The problem is that it never seems to get an answer. I get the checkpoint popup when I click the map so I guess that this part is executed well. But it stays forever with the loading message. So probably "wmsLayer1.getFullRequestString" is not correct or my database is not quite right... I just have a layer with points. And I want to query information about thoise points in the database to display it beside the map. I'm using a local Geoserver with PostGIS. I would like to know too how the getFeatureInfo query works. Like if I have anything I have to do specially into the database. I figure that it's querying the database for info, but what info? Do I have to define what I want to be queried? Maybe this is off-topic here sorry. I searched for informations on the UTIL package for openlayers but didn't find real documentation about that. Please let me know if you would like more info. Any help will be greatly appreciated. Thanks in advance /******* CODE START HERE - !!! Note that this code is not complete.

In the function triggered, I deactivate any DoubleClick map event with map.events.remove('dblclick'); and then register a DoubleClick event to do a getFeatureInfo on a mouse doubleclick. This works fine but after doing this once the standard DoubleClick (recenter & zoom) has of course been deactivated. I would like to reactivate just the DoubleClick to do Zoom & Recentre when selecting an active layer that is not queryable.

If you are using zoom levels (and not just free zoom scales) find out the zoom level for your extent with something like: var zoomlevel = map.getZoomForExtent(ci.Bounds); This should make sure that your entire extent is in the view port. Then use a setCenter with the center of your bounds and the zoomlevel. Like I said, this might not apply in your case.

Yang: That particular code appears to be from MapBuilder, rather than from OpenLayers. Can you confirm that? I don't have enough experience with that particular chunk of code to recognize what 'getElements' is doing -- in general, OpenLayers has a wrapper function: OpenLayers.Ajax.getElementsByTagNameNS(data, this.gmlns, "gml", this.featureName); which works on IE.

You must create three seperate selectfeature controls. (The openmnnd.html demo shows how to set up two, I think.) Only one can be enabled at a time. This is, as they say, 'just the way it works'. http://trac.openlayers.org/ticket/434 is a tracking bug for fixing this: I think Cameron has a desire to change it, but no code currently exists for this in OL. -- Chris > many thanks > > /*******************************************************************/ > var gml110=new OpenLayers.Layer.GML("110kv", > "110.xml",{style:style_yellow}); > map.addLayer(gml110); > > var gml220=new OpenLayers.Layer.GML("220Kv", "220.xml",{style:style_red}); > map.addLayer(gml220); > > var vectors = new OpenLayers.Layer.Vector( "Editable Vector Layer"); > map.addLayer(vectors); > map.addControl(new OpenLayers.Control.EditingToolbar(vectors)); > > var vctoptions = { > hover: false, > onSelect: displayWKT > }; > > var drawControls = new OpenLayers.Control.SelectFeature(gml110, vctoptions); > map.addControl(drawControls); > drawControls.activate(); > /*******************************************************************/ > -- > View this message in context: http://www.nabble.com/How-to--Add-Multi-Vector-Layers-into-SelectFeature--tf4079356.html#a11594470 > Sent from the OpenLayers Users mailing list archive at Nabble.com. > > _______________________________________________ > Users mailing list > Users@openlayers.org > http://openlayers.org/mailman/listinfo/users > -- Christopher Schmidt MetaCarta From bwoodall at bwoodall.org Mon Jul 16 13:11:04 2007 From: bwoodall at bwoodall.org (Bill Woodall) Date: Wed Sep 1 17:15:37 2010 Subject: [OpenLayers-Users] Problem with zoomexents and google maps layer In-Reply-To: <469B8401.6040507@swoodbridge.com> References: <4697F20E.9060606@swoodbridge.com> <20070713225529.GA21774@metacarta.com> <469B8401.6040507@swoodbridge.com> Message-ID: <1184605864.25985.20.camel@wardrobe.dhs.org> Hi Steve, After looking at your example I noticed that you are using CSS (width:100%) for your map div and thus the browser will set the viewport width and the viewport might never equal the bounds you set. ......Bill, On Mon, 2007-07-16 at 10:43 -0400, Stephen Woodbridge wrote: > Chris, > > Attached is an html test case.

I have a feeling that the problem here is the same as all problems with the Google layer -- OpenLayers assumes that it is unprojected, when in reality, it is projected. This only works so well. I'd say this can be filed as a bug against OL2.5, though it's possible my resolution of the ticket will simply be "Switch to the new GoogleMercator Layer" once that gets into trunk. -- Chris From jdege at korterra.com Mon Jul 16 17:47:27 2007 From: jdege at korterra.com (Jeff Dege) Date: Wed Sep 1 17:15:37 2010 Subject: [OpenLayers-Users] Problem with GML coordinates? Message-ID: <34E056CD4D475841B8C9ABCE956F92F6370A85@mrburns.KorOffice.local> I've been working with the OpenLayers.Layer.GML, and things have been working, mostly. I've been working with the default EPSG:4326 projection, but my users don't like the looks of it. (Decimal degrees are stretched, left-to-right.) So I've been trying to convert things to EPSG:102004. My original GML files had been converted from shapefiles using ogr2ogr, with no SRS specified. Since the shapefiles had been in EPSG:4326, everything was fine. I created new GML files, specifying a conversion to EPSG:102004, set the projection and units options in the OpenLayers.Map() constructor, and nothing worked at all. The generated map is a collection of random-looking sharp spikes. So I edited the GML file to cut it down to having only one rectangular feature. And OpenLayers drew it all catywhompus. Comparing the GML file that worked to the GML that didn't, the one that didn't had three-dimensional coordinates: -634517.11999089224,691849.77929356066,0 -653761.64509297756,471181.53429472551,0 -673343.60852865304,250906.9515983529,0 -1088825.734430399,299284.85108220269,0 -1254041.3897117018,324729.27754874947,0 -1235750.4212498858,434167.33911316615,0 -1190777.7803201093,704392.96327195223,0 -1181607.835811228,762236.29408003774,0 -634517.11999089224,691849.77929356066,0 The one that did had two-dimensional coordinates: -104.05769844520292,44.997431638295993 -104.05312407321384,43.000582772448595 -104.05324668521079,41.001406996991136 -109.05007717114714,41.000661173718115 -111.04672699029817,40.997960720571911 -111.04669077447262,42.001566700961526 -111.04897415303213,44.47407102095351 -111.05519878435098,45.001322181741365 -104.05769844520292,44.997431638295993 When I edit the gml file that didn't work to remove the third dimension, things draw just fine. I'm no expert on the GML specification, but my expectation would be that if the ogr tools can create GML files with three-dimensional coordinates, then the GML specification probably allows for it. In which case, OpenLayers.Layer.GML should probably cope with it, even if it's only throwing the third dimension away.

IT looks for an > srsDimension attribute on the gml:pos or gml:posList elements. I think that's the problem. It's assuming that if it uses gml:coordinates, it's GML2, and if it's using gml:pos or gml:posList, it's GML3, and that if it's GML2, it only has two dimensions. Now I'm not sure whether ogr is incorrect in using three dimensions in a gml:coordinates element, or whether the GML format class is incorrect in assuming that the lack of gml:pos or gml:posList indicates two dimensions.

Great. This is clearly a bug, and should be fixed in the Format.GML class. Erik, can you file a ticket for this, marked for 2.5, and attach the output file to the ticket as an attachment so we don't lose it? That way I'll have the data to test against when I'm fixing it.

Chris, John, Thank you for the assessment. I was afraid this was going to be the case. I did a lot of checking on our end before posting. I'm sorry it was not initial clearer. Anyway, I'm looking for a work-around. If we could do something like: var zoomlevel = map.getZoomForExtent(ci.Bounds); var bounds = map.getExtentForZoomLevel(zoomlevel); if (overlaps(bounds, ci.Bounds) && zoomlevel > 0) zoomlevel--; I think this would work. How would we do the equivalent of: var bounds = map.getExtentForZoomLevel(zoomlevel); I haven't checked but I doubt that that function already exists. -Steve From crschmidt at metacarta.com Mon Jul 16 21:29:24 2007 From: crschmidt at metacarta.com (Christopher Schmidt) Date: Wed Sep 1 17:15:37 2010 Subject: [OpenLayers-Users] Problem with zoomexents and google maps la yer In-Reply-To: <469C1A48.2000208@swoodbridge.com> References: <76758090F8686C47A44B6FF52514A1D307909DB1@hermes.uai.int> <20070716201440.GA12256@metacarta.com> <469C1A48.2000208@swoodbridge.com> Message-ID: <20070717012924.GA13309@metacarta.com> On Mon, Jul 16, 2007 at 09:24:24PM -0400, Stephen Woodbridge wrote: > Anyway, I'm looking for a work-around.

If we could do this accurately, we wouldn't be having this discussion, since this is how the code is already supposed to work :) The problem is that because Google isn't linear, the only way we have of getting accurate corners from a center and zoom is to zoom there, and ask the Google layer.

The issue seems to be that the controls don't have the same parent div as the popup/layer divs so the z-order doesn't help. I'm guessing the controls would have to be specifically placed inside the "OpenLayers_Container" div for this to work.

Any help would be appreciated. In general, the way OpenLayers works is to *not* expose the lower level interface -- in fact, if you just want to use the Google Maps API, you probably want to be using something like Mapstraction (http://www.mapstraction.com/) instead of OpenLayers. However, you can use the OpenLayers.Popup classes.

I tried the suggestion I gave you and the whole layer floated over the controls. not good. I'm not sure this can actually be done. Since the popups by default live in the container and the controls live parallel to the container... it might not be possible:

I've just noticed I got the logic in the forwardMercator41001 function slightly off, and I had the x and y variables the wrong way around The attached patch gets them right, and also allows you to specify a projection property to the constructor, so it can get the max resolution correct (41001 and 54004 have a very slightly different one). It's against the latest tschaub sandbox checkout.

One of the features I beileve you mentioned wanting was the ability to have popup automatically slide into view. Great, in theory. Except that as soon as that happens, the Google Map has moved without the OpenLayers map moving at the same time. The end result is that OpenLayers and Google have a different idea of where the map is centered, which results in crazy behavior in extreme cases, but in all cases is going to be behavior that users don't want. The events model in OpenLayers doesn't cooperate well with Google popups -- zoomboxing and letting go over one will get your zoombox 'stuck' so it can't be released. etc. What seems like a simple solution leads to a number of interface issues. Not exposing the object is a design decision based on this type of problem, and although I understand the desire, it's not something we can support without creating more problems than we solve.

In the meantime, I know that this is "normal behaviour" of the mapserver, because he doesn't know, that OpenLayers is going to get an other tile right next to it and therefore doesn't display a part of a discription from an object not in this tile. Problem 2: With OpenLayers.Layer.WMS.Untiled: When entering the map, everything seems fine. But as soon as I zoom in, only a little part from the MapServer is visible above the Google Layer. When moving the map around a few times, it gets visible. When zooming in again, same thing: I have to move the map around to make everything visible that should be there. I think this is a OL problem. See this: http://map.webser125.lookass.ch/openlayers/ex_rpag_google2.php You can see a fwe objects (white arrows, ...). When you zoom in, only one arrow is visible at the top left (there should be more things in the center area). Moving the map around and back to where you were makes the other things visible...

I was working with resolutions and scales and tilecache and I was trying to adjust everything to have a set of predefined levels corresponding to fixed scales (1 : 1M, 1 : 500 K, ...). I seems that in fact it's better to works with resolutions instead of scales when using tilecache and that the base extend should correspond to 2x2 tiles at the max resolution. I have a TIFF file in 3200 meters per pixel, I've had to adjust my EXTEND so that it correspond to 3200*512 to avoid rounding problems and missing tiles. Now, the scale controller show a scale based on the following calculus : 3200 pixels/meter * 72 ppi * 39.3701 inch/m --> 1 : 9 M The 72 ppi and 39.3701 inch/m values are defined in the Utils.js 72 ppi is the same value used by Mapserver by default. I've made a some research on Internet to understand how it works and maybe we should add a little note on the OpenLayer site. All this to say that if I understand well, we should rename the variable "DOTS_PER_INCH" of the Utils.js file into "PIXEL_PER_INCH" to be more correct (I know, I should have done more important things this morning ^^) . http://www.scantips.com/no72dpi.html http://en.wikipedia.org/wiki/Pixels_per_inch http://en.wikipedia.org/wiki/Dots_per_inch Tchule. _________________________________________________________________ http://imagine-windowslive.com/hotmail/?locale=en-us&ocid=TXT_TAGHM_migration_HM_mini_2G_0507 From myardbenoit at gmail.com Wed Jul 18 04:04:45 2007 From: myardbenoit at gmail.com (Benoit Myard) Date: Wed Sep 1 17:15:37 2010 Subject: [OpenLayers-Users] WMS in OpenLayers: Objects get Cut In-Reply-To: <929074CD8C635346B3FFFEFACDE01B45019B215A@exrpmu1.ingnet.local> References: <929074CD8C635346B3FFFEFACDE01B45019B215A@exrpmu1.ingnet.local> Message-ID: <6fb81fc70707180104h19709793mc04b68f94bef5192@mail.gmail.com> Now I understand.

So please, use this piece of code in your page : var satellite = new OpenLayers.Layer.Google( "Google Satellit" , {type: G_SATELLITE_MAP, 'maxZoomLevel':19} ); var karte = new OpenLayers.Layer.Google( "Google Karte" , {type: G_NORMAL_MAP, 'maxZoomLevel':19} ); var hybrid = new OpenLayers.Layer.Google( "Google Hybrid" , {type: G_HYBRID_MAP, 'maxZoomLevel':19} ); map.addLayers([satellite, karte, hybrid]); var layer = new OpenLayers.Layer.WMS.Untiled( "RPAG", "http://map.webser125.lookass.ch/cgi-bin/mapserv?map=/home/web/web4/data_rpaglocation/rpag_lp_test.map", {layers:'anfahrtsweg,oeffentlicher_verkehr', transparent:true, format:'image/png'} ); map.addLayer(layer); Now please, let us know if the problem is still there. -- Benoit Myard From myardbenoit at gmail.com Wed Jul 18 05:28:15 2007 From: myardbenoit at gmail.com (Benoit Myard) Date: Wed Sep 1 17:15:37 2010 Subject: [OpenLayers-Users] WMS in OpenLayers: Objects get Cut In-Reply-To: <929074CD8C635346B3FFFEFACDE01B45019B215C@exrpmu1.ingnet.local> References: <929074CD8C635346B3FFFEFACDE01B45019B215C@exrpmu1.ingnet.local> Message-ID: <6fb81fc70707180228h22dc72c5q5fd988e3938a31f9@mail.gmail.com> > Is it a bug actually?

This is functionality which we plan to add to OpenLayers in the relatively near future. I'm hopeful I'll get time to write it for 2.5, but I think it may not go in until 2.6. There are some difficulties -- for example, if it's a WFS layer, moving the map by a few pixels in any direction may end up redrawing the WFS layer -- but I'm hopeful we can create a solution for the simple cases, at least.

I exchanged some emails on the geoserver mailing list and they suggested me to try the preview maps given by geoserver. They now integer the getfeatureinfo functionality in the default previews. So I tried there and everything worked fine. but, now, if I copy the html code entirely without any modification into my webpage, I won't work. The map displays fine and everything. But it hangs on the loading message and never get response. I used Firebug to track the bug and I remarked that the request is never noticed in firebug when I click on a point. The loadURL function is called but not the setHTML. It makes me think that maybe it's a permission problem. Since it semms to work from geoserver itself but not from apache (which my web page is on).

Isn't there like a function that will move the map 1 px everytime you change zoom? Or another workaround for this? Is it a bug actually? There is definitely a bug here. The problem is that the bounding box requested for the tile is not actually in the right place -- it's off by about .02 degrees, it looks like, which is a fair distance. Could you try upgrading to the latest svn code -- svn co http://svn.openlayers.org/trunk/openlayers/ will get the code for you -- and see if it still happens? It looks like you're currently running against 2.4-RC2, and although I'm not really hopeful that this change will fix the problem, I'm hopeful that it will at least elmiinate that as part of it. Another question -- did you see this with tiled layers as well? I think the answer is yes, but I can't remember. Thanks in advance for trying to help us dig into it.

(Looks like I mistakenly sent to user instead of to list -- ) The problem here appears to be that the bounding box for the tile is off in both directions by a significant amount, which results in the tile not having the correct data. Could you try updating the code to run against SVN head -- you can point to http://openlayers.org/dev/lib/OpenLayers.js temporarily to do so -- and see if the behavior changes at all? Also, just to confirm -- this problem happens with WMS Tiled layers too, correct? I just want to make sure that this isn't a problem with OL-2.4 RC2. I doubt it, but you never know.

It loads information for your markers from a text file (with a custom icon for each if you like) and displays a popup with information relevant to that marker (also loaded from the text file). It does not, to my knowledge, do so on just a mouse-over, the user has to click on the icon, but I imagine that wouldn't be too difficult to finesse. There has been considerable traffic recently regarding having scrollbars in these popups as well, so if that is a need, you can do it too. Good luck, r.b. var newl = new OpenLayers.Layer.Text( "text", {location: "./wateruse.txt"} ); map.addLayer(newl); -----Original Message----- From: dev-bounces@openlayers.org [mailto:dev-bounces@openlayers.org] On Behalf Of Bradley Mclain Sent: Wednesday, July 18, 2007 7:29 PM To: Mapserver Users ML; OpenLayers ML Subject: [OpenLayers-Dev] Information/Advice about placing markers Ok what I want to do is place a series of markers on different farm blocks and properties, I currently have a Webserver using OpenLayers to import Google Maps and my own custom Mapserver WMS data. I am looking for any advice hints and tips on how to go about all of this. I have a list of all the info I need about the different farm blocks, names of growers, variety of produce etc and I would like to place a marker so that when you hover over it it displays this data. (Also a potential future feature would be a full outline of the property but this is probably a while off. Currently all I have is markers being placed on the specific locations with no pop-up info or anything. I don't want to cram my html file full of this info and would prefer if I could import from some sort of a database or text file. (Preferably textfile in the short term for testing but eventually a database would be ideal). Cheers Brad -------------- next part -------------- An HTML attachment was scrubbed...

It has made my life a lot easier in this latest project I am working on, so thanks! I'm having an issue with my vector image flashing when I pan around the map in IE7. I can reproduce the same effect in the demo: http://dev.openlayers.org/sandbox/vector-2.4/examples/vector-features.html When you pan the map the vector images moves nicely along with the map but when you release the mouse the vector flashes in its original starting position for a fraction of a second and then is back where it is supposed to be.

To those who don't know (like me), you can't access a host with your browser and make query on another. The point I was missing was that the same machine with 2 different ports are considered to be 2 different hosts. It's a simple explanation when you realize that. I learned too why the security exception in Firefox while I attempted to make request (via Firebug) didn't show like I would have expect. That's a thing that really bothered me at the first place because I would have expected an clear error from the browser. I have read that this kind of exception are treated silently in the browser so it's normal I've seen nothing while I was debugging. Now everything is working well!

Actually, that's not entirely true. Instead, this is a failing of OpenLayers.Ajax, which has since been corrected in trunk: http://trac.openlayers.org/ticket/534 So, had you been using SVN, you would have seen "Unable to call XMLHttpRequest.open".

The URL should look like this: http://yourhostname/cgi-bin/mapserv.exe?map=yourmapfilepath&REQUEST=GetFeatureInfo&...&layer_youlayername_class_yourclassname_tolerance=5 whereby "yourlayername" and "yourclassname" stay for the layer name and the class representing the layer as defined in the mapfile. If you are using another GIS server as for instance GeoServer, that doesn't support mapfiles and custom classes, you should look for a workaround. I would suggest to use the GetFeature request (WFS service) instead of GetFeatureInfo (WMS), because in this case you don't have to explicitly define the map position (parameters X and Y). Instead of this you only type a BBOX (minimum and maximum values for latitude and longitude) in your URL, which defines the area of interest, and the response you get from the server will contain all the features in this box. The BBOX could easily be computed via javascript. If none of those suggestions is helpful, please describe your configuration and your actions in detail so I could exactly understand what you are doing and what you're trying to achieve.

What I meant is setting the tolerance via URL, in your case it would be sth like http://youhost/...&map_layer_0_tolerance=1&map_layer_0_toleranceunits=feet(I don't know if the underscores in your layer name won't affect the functionality so I'm assuming that it is the first layer in the mapfile and using the index of it).

(By the way is openlayers not using prototype anymore?) Mootools has a post for beginning (and mediocre) javascript coders: http://blog.mootools.net/2007/6/5/help-i-dont-know-javascript. Especially the yahoo-video's of douglas crockford were an eyeopener for me! Concluding: - if you want to understand a little more about some constructs/concepts in Openlayers, or want to learn how to code javascript a little cleaner: do take some time to view the video's of douglas crockford and Nicholas Zakas: http://video.yahoo.com/video/play?ei=UTF-8&b=4&vid=568351&gid=133414 - really have a look at the documentation of firebug (I was using it, but didn't know it had so much possibilities): still using alerts? read: http://www.getfirebug.com/logging.html - still not using the debugging features of firebug? see http://video.yahoo.com/video/play?vid=111597 - wouldn't it be nice to have something like http://blog.mootools.net/2007/6/5/help-i-dont-know-javascript in the openlayers (users) wiki? After seeing all this, http://www.liveearthalert.nl/static/javascript/maps.js showed me a nice example to organize (application) code. Look a lot better then mine. Is it an idea to add such an example in the examples, using the Openlayers constructs (use a 'namespace', use the Ajax and 'class' code of OL, organize your constants etc etc)?

I downloaded the latest svn version (I think it worked, I don't have SVN, did it with "wget -r"). http://map.webser125.lookass.ch/openlayers_svn/ex_rpag_google_untiled.php Copied the file that includes OL in there and still the same thing happens. As you see, this does only happens with OpenLayers.Layer.WMS.Untiled. Without "Untiled", it works: http://map.webser125.lookass.ch/openlayers_svn/ex_rpag_google.php But I have other problems with that one: My mapserver doesn't continue object descriptions in tiles that end in other tiles. I know this can be fixed with "tilecache" or tools like that, but this one seems to be a bit too complex for that I just want a simple WMS displayed in OL the right way. Do you want me to add these new links to the Bug report too? I will for sure keep them online until it is fixed (I saw milestone is 2.5, gonna take a while though?).

Isn't there like a function that will move the map 1 px everytime you change zoom? Or another workaround for this? Is it a bug actually? There is definitely a bug here. The problem is that the bounding box requested for the tile is not actually in the right place -- it's off by about .02 degrees, it looks like, which is a fair distance. Could you try upgrading to the latest svn code -- svn co http://svn.openlayers.org/trunk/openlayers/ will get the code for you -- and see if it still happens? It looks like you're currently running against 2.4-RC2, and although I'm not really hopeful that this change will fix the problem, I'm hopeful that it will at least elmiinate that as part of it. Another question -- did you see this with tiled layers as well? I think the answer is yes, but I can't remember. Thanks in advance for trying to help us dig into it.

A click event on a map returns the values for x and y in the view port. You should make a box of those adding and substracting a custom tolerance value. After you've done so you got 4 values: minx = x - tolerance, miny = y - tolerance, maxx = x + tolerance, maxy = y + tolerance. These can be converted to latitude-longitude values using OpenLayers ( map.getLonLatFromViewPortPx function). After all of these actions you get your BBOX so you can send a request to the geoserver like this: http://your_host/geoserver/wfs?REQUEST=GetFeature&SERVICE=WFS&VERSION=1.0.0&TYPENAME=your_layer_names&BBOX=your_bbox&MAXFEATURES=10 That's the only workaround I know.

If the requested map extent falls outside maxExtent in any direction, the returned extent is adjusted by the difference. If the requested map extent is completely outside the maxExtent in any dimension, the returned extent is centered on maxExtent. I will follow up on the dev list, and see what we need to do to make this happen. I've punted on it for far too long, and it's time to stop.

The problem is that for now they do a getinfo on the coordonates of the geometry (a point in my case) instead of the representation (likely a circle for me). The representation is larger than the geometry so you get the feeling you can click anywhere in the cercle to get info. By reality is really different ;) This issue is opened in their bug base so I guess it will be fixed in the next versions.

I would like to ask for help from the openlayers community as to possible ways to improve the performance of the map. In return you'll get lots of good karma, mention in our code and on our blogs. Not much, I know, but it's all I can offer... My base data is served from an indexed postgresql/postgis database (there are a couple of thousand points in it). I know that I can't use tilecache with either the Virtual Earth or Google Earth base layer, so that's out of the question unless someone can point me in the direction of a base layer that does something similar to what I currently have. I have tried both mapserver and geoserver to serve the wms, and for the moment am using mapserver because it seems a little quicker. Any pointers that people can give me on tuning the performance (even if it's just to tell me to go and see the mapserver/geoserver folks) would be extremely gratefully received!

When I draw a feature and then save it into my PostGIS Table (FID serial not null, THE_GEOM geometry), I receive a commit succes response, the feature is correctly saved into my database, but in OpenLayers when I display the featureId (fid) of this feature, fid = null. And the only solution which I found to retrieve the fid is to refresh the layer...and to display the fid after that. Have you an idea from where the problem can come ?

Message-ID: <34E056CD4D475841B8C9ABCE956F92F6370AAB@mrburns.KorOffice.local> I'm trying to add the OverviewMap control to a map built with KaMap layers. I'm using OL version 2.4. The example - examples\overviewmap.html - works perfectly. Mine doesn't work at all. When the OverviewMap control requests tiles from KaMap, the tiles are generated correctly - or at least they seem to. The directory structure looks fine, and the generated GIF files look fine. But the tiles that are actually being requested don't correspond to any of the tiles that were generated. The URL of the tile that was requested: http://localhost:8080/servicearealookup/tile.php?map=mississippi&g=all&i =gif&t=-768&l=-1536&s=19686393 Top is -768, left is -1536, scale is 19686393. In the KaMap cache, there is a directory for scale 19686393, and in that a subdirectory for group "all", and for layer "def". And in that, there is a subdirectory t-1200l-2400. In that, there are 36 GIF files, all of them blank except one, t-600l-1600.gif, which contains the image that should be being drawn in the overview map at this scale. (Zoomed out all the way.) Now I seem to remember having had a similar problem with KaMap on the main map, because the default tile size in OpenLayers was 256x256 and in KaMap was 200x200. Which I fixed by setting the tilesize option to the OpenLayers.Map constructor. So I passed a tilesize option to the OverviewMap constructor, and it made no difference.

You'll want to construct your overview map with some non-default options. Set the mapOptions property of the options object as in the example, and you should get what you want. To quote from the wiki: The thing to keep in mind here is that the OverviewMap control is a control, not a map. This is an important distinction. The OverviewMap control *has* a map, but *it is not* a map itself. To set options on the control, use properties of the options object as you would with other controls. To set properties on the little map that the OverviewMap control controls, use the special mapOptions property of the options object.

Yep, that's what I missed. > You'll want to construct your overview map with some non-default > options.

There are options I'm passing to Map() that I apparently don't want to pass to OverviewMap. My first attempt, I created a mapOptions variable, and passed it to both constructors (as options, in Map(), as options.mapOptions in OverviewMap.) That didn't work. I had been setting Map.scales. That's inappropriate for OverviewMap. Letting OverviewMap pick its own scales seems to work fine, but if you want to force a set of scales, they'll most definitely not be the same as you're using in the main map. But one thing I've noticed. Most controls have the option of being placed either over the map, or in divs outside the map. MousePosition, for example, or Scale, or Permalink, all accept element as on option argument, and create their own, attached to the map, only if it isn't passed. OverviewMap does not allow for this. It only allows the overviewmap to be drawn over the map itself. Is there a reason for this?

I am figuring things out. When I attempted to set the 'div' option, I got a crash. On examination, it was because I had originally done a OverviewMap.maximizeControl(), immediately after adding the control to the map. If outside the viewport, we don't have minimizeDiv or maximizeDiv. My fault. I think I've pretty much got everything working, now. Thanks for your help.

I'm not sure what you mean. Your maxresolution in openlayers and TileCache don't match. You should make them match. (And then clear your cache.) Additionally, I would recommend using: new OpenLayers.Layer.WMS("all", "http://192.168.1.160:8080/", {'layers':'all'}) instead of what you're currently using, because TMS is not as well tested as WMS. TMS doesn't care if your tiles are off. WMS does, and would have told you so. > What is the diference between maxResolution and resolutions? resolutions is a list of resolutions. maxResolution is a top level, which is then divided by 2 many times to get a list.

Problem is, as I said before, that I can get out of maxExtent when dragging. After patching, it seem that app work fine when I avoid all error message and complete zoom in, but when come to some 'border' between maxExtent app stop working and i have alot of errors. Javascript error that I get after patch evry time when I'm try to drag is lonLat has no properties: MousePosition.js 87: lonLat.lon.toFixed(digits) in news.txt first line is "OpenLayers 2.0 Release Notes" is that meen that version of OL is 2.0? :) From tylersticky at gmail.com Thu Jul 26 11:27:33 2007 From: tylersticky at gmail.com (Tyler Durden) Date: Wed Sep 1 17:15:38 2010 Subject: [OpenLayers-Users] Resolutions problems In-Reply-To: References: <20070726113728.GC13812@metacarta.com> <20070726132754.GA14279@metacarta.com> Message-ID: Ok, I figured out.

After changing base layer to GoogleMaps it looks nearly ok. Very small shift is almost visible only (scale 1:28M). But after zooming in to scales < 14M all layers are aligned exactly already. Zooming out to scales > 14M makes layers unaligned more and more. Second case: After changing WMS layer to WMS.Untiled: behaviour is the same as in previous case but layers aligns under 1M scale. At scale 1:14M there is shift by whole country and overlay is stretched vertically very much. Additionaly, overlay do not show always. Sometimes dragging makes it show on map. Third case: After changing to Mapserver layer: -On OL WMS everything ok -On GoogleMaps overlay is not stretched (looks like unprojected data) and shifted north by 2 countries (scale 1:28M) -zooming in to scale <50K makes layers almost aligned -while zooming in, sometimes there are no tiles at the bottom of the map. Fourth case: Mapserver.Untiled: -On OL WMS everything ok -On GoogleMaps overlay is not stretched (looks like unprojected data) and shifted north by 1/2 countries (scale 1:28M) - zooming in has no effect on layers align How can I get OL 2.5 ?

One labeling process doesn't know about the other. One solution would be to use a smarter tiling engine than simply WMS. I believe both TileCache and ka-map both support the concept of metatiles which can really help with this problem.

I can't imagine how that would work. You're going to need some kind of layer inbetween that speaks a non-binary language. FeatureServer is a Python CGI that is designed to speak a variety of languages on the input side and output side, and is designed to be as little work as possible to install.

So, in my modified WFS.js, I have created a method that takes all created shapes and places them in a POST array, which is then read by a php script which has access to the PostGIS constructirs for setting the SRID(epsg), code follows: Javascript: --> var wktObj = new OpenLayers.Format.WKT; for(var i=0; i BEGIN php: $wkt = $_POST['WKTDATA']; #print_r($wkt); $i = 2; foreach ($wkt as $thiswkt) { $listobject->querystring = " insert into proj_features (gid, name, the_geom) "; $listobject->querystring .= " select $i, 'test shape', GeomFromText('$thiswkt', 4326) "; print("$listobject->querystring "); $listobject->performQuery(); $i++; } END php -----Original Message----- From: arnd.wippermann@web.de [mailto:arnd.wippermann@web.de] Sent: Monday, July 30, 2007 4:34 PM To: Burgholzer,Robert Subject: AW: [OpenLayers-Users] writing to my own wfs server Hello Robert, I have a look at the wfs-t.html and have seen, that the feature.geometry is a WKTString. Perhaps you can use this instead of the XMLserialization. After adding the EPSG-Code to the WKTString you can insert the string into the geometry column of your db.

I use the editing functions of openlayers to draw a feature, select that feature and use a serverside asp-script to insert the selected feature as WKT string via odbc into an access-db. With mapserver and ogr I can request the geometry and attributes from the access-db and show it in the map. It is also possible with a WMS GetFeatureRequest to select features from the db and delete the features in the db with odbc. When the great editing tools from openlayers get the possibility to update features (changing the geometry after drawing it), one can use an internet explorer and openlayers for drawing, updating and deleting geometry data.

I can't imagine how that would work. You're going to need some kind of layer inbetween that speaks a non-binary language. FeatureServer is a Python CGI that is designed to speak a variety of languages on the input side and output side, and is designed to be as little work as possible to install. However, it requires some level of configuration, and it is likely, or even possible, that you would be better off with GeoServer.

Only with OpenLayer. You can't. OpenLayers is a client side display application. You will need server side software to serve the data as vectors or render it into images -- most likely, you're looking for a WMS Server like MapServer or GeoServer.
