Subject: [OpenLayers-Users] Using getFeatureInfo on a vector (WFS) layer in
	openLayers
Message-ID: <1283314177551-5485412.post@n2.nabble.com>


Hey OL....
I'm trying display the data associated with a feature (point) in a vector
(WFS) layer using the script below
When I click on the feature I get the message: 
No QUERY_LAYERS has been requested, or no queriable layer in the request
anyways 


I've used both 
"http://tobagoborn.com:8080/geoserver/WMS",
and
"http://tobagoborn.com:8080/geoserver/WFS",

as the URL in the getFeatureInfo part of the script

<script type="text/javascript">

            var map;
            function init() {
                map = new OpenLayers.Map('map', 
                {
                    maxExtent: new OpenLayers.Bounds(-10.0, -1000.0, 600.0,
1700.0)
                }
                );

                var basicflr = new OpenLayers.Layer.WMS(
                    "Floor Plan",
                    "http://tobagoborn.com:8080/geoserver/wms",
                    {layers: 'monitor:Admin'}
                );

                var wireless = new OpenLayers.Layer.WFS(
                    "Wireless",
                    "http://tobagoborn.com:8080/geoserver/wfs",
                    {
                      transparent:'true',
                      typename: 'monitor:Routers'}
                );


//                map.addControl(new OpenLayers.Control.LayerSwitcher());
                map.addLayers([basicflr, wireless]);
                map.zoomToMaxExtent();

              // support GetFeatureInfo

I understand.. I'm sure this solution is very good but unfortunately I MUST
(and I'm not happy of this) use an Oracle db and I haven't access to it
(cannot configure extensions, plugins, etc.).
So the only way for getting the coords is querying them with a SELECT
statement from a php page and arrange them in a format suitable by
OpenLayers.

Other suggestions?   ;-)

btw thank you Piero for your help.. it reminds me I'm not using the best
available tools.. :-(

Hello,
finally i got the proxy.running. The problem came up due to the  
application running on glassfish (port 8080) and the cgi script being  
run by Apache (port 80)
So I had to add "myApache_URL/" to the path of OpenLayers.ProxyHost

However, the request now is forwarded to the external MapServer, the  
response (format = html) seems to be O.K. (status = 200) but the  
GeoExt.popup ist still empty.

Definition of WMSGetFeatureInfo is:
     var featureInfo = new OpenLayers.Control.WMSGetFeatureInfo(
                            {
                            vendorParams: {map: 'PathToMap.map'}
                            }
                        );
             featureInfo.events.on({
                 getfeatureinfo: function(e) {
                     new GeoExt.Popup({
                         title: "Info",
                         width: 200,
                         height: 150,
                         autoScroll: true,
                         maximizable: true,
                         map: map,
                         lonlat: map.getLonLatFromPixel(e.xy),
                         html: e.text
                     }).show();
                 }
             });

Is there still anything missing, that I forgot to define or defined  
the wrong way?

cheers,
Sven

Subject: [OpenLayers-Users] How to change WMS layer on the fly?
Message-ID: <1283336611934-5486278.post@n2.nabble.com>


Hi all,

I'm struggling with a peculiar set up: we have a WMS layer in OpenLayers
(within a GeoExt web interface) invoking a MapServer string (e.g.
http://mydomain/cgi-bin/mapserv.exe?map=someMapFile.map&etcetc).
Now we need to split the dataset into several layers.
We tried by instanciating n separate WMS layers and it's way too slow, so
we're trying a pretty simple solution: generating a custom mapFile
containing only the required layers. This dynamic mapfile is returned by a
service:
http://mydomain/myservice/get?layers=listoflayers,otherparams,etc that
returns the path to the custom mapfile. This solution is very simple and
efficient.
So now we should update the WMS layer in order to replace this mapfile on
the fly, without reloading the whole page.
So my questions are:
- Is this possible?
- Is it ok to have a separate layer list (not the default one offered by
OpenLayers) and trigger an event "changeLayers"? Are there any examples of
this setup?

Thanks in advance for any hints!
Mulone

Message-ID: <1283339434457-5486415.post@n2.nabble.com>


Hello everyone,
I followed one of the examples provided by openlayer, to allow users to draw
geometries:

http://svn.openlayers.org/sandbox/stvn/arcgis-server/examples/wkt.html

I have, for the geometry designed,  an info window containing the
coordinates in WKT format;
Can someone help me understand how to insert geometries in a database?

thanks a lot!

  Hello,

Yes it is, OL supports the usage of an SLD with vector layers such as 
WFS or GML, but its slow and it does have its limitations. If you can it 
is better to have those layers rendered through WMS telling the server 
which SLD to use

Sure, check out the sld.html example. This works with Layer.GML, but the same should apply to Layer.Vector.

Hi,

I am actually trying to load a shapefile into openlayers and have all the 
attributes listed into a table under the map. I have completed this using a wfs 
layer, but am now looking at getting some 

scale dependant symbols into the map as well with the use of an SLD file.

Is there maybe a better way of completing this?

Yours,

Rob

hi paolo,

you've got to have a database with GIS extension. I use mysql. mysql 4.1 and
above supports GIS and spatial extension.

my application is written in php with mysql. I use phpmyadmin to manage my
db

inserting can be as simple as this
-------------------------------------------------
insert into my_geometries (my_id,geometries) values
('$my_id',GeomFromText('$geometries'))

and retrieving like this
-------------------------------
select AsText(geometries) as geom from my_geometries where my_id='$my_id'

to view geometries from phpmyadmin, please use the latest phpmyadmin
version.

hope that helps,

remi

BMcBride,

Thanks a lot! Finally i found a way how to use the proxy with IIS. Works
perfect for me!!

Cheers,

Hey Alberto,

I've had luck using PHP with a SELECT statement on a MySQL database to write
a KML file for use in OpenLayers.  As long as your query returns a
relatively small subset of features (<500) and your users have a snappy
connection with a decent browser, you should be OK using this method. 
Fortunately you are returning point features with a single set of coordinate
pairs, as opposed to complex polygons!  A benefit of using KML is that you
can also let the user download the results in a fairly common and readily
usable GIS format without having to write any additional code.  If you are
interested I can post my MySQL -> KML PHP script.

Best of luck!

BRYAN

hi thanks for the reply, I have a question then as to be amended this
statement ( OpenLayers.ProxyHost = "/cgi-bin/proxy.cgi?url="; ) for file
proxy.php since the requests are not processed or the system is awaiting a
response.

Thanks again and suggest

thanks!
First of all I have to create a script that retrieves the string on the
server, and then an insert query in geodabase (like the one you suggested),
this is the right procedure?
regarding the script I can elaborate on some one that already exists?
because I'm not able to write a new one ...

thanks again!

You can't use getFeatureInfo against a WFS as it is a WMS request. You
would need to use a GetFeature request against the WFS. Look at the
demo requests provided by GeoServer to see the differences. Or
http://dev.openlayers.org/releases/OpenLayers-2.9.1/examples/getfeature-wfs.html
for a working OpenLayers example.

I had a need for simply displaying thousands of css styled points from a SQL
Server db (no need for click handlers) and ended up creating a custom tiled
vector layer.  The points are created as img tags.  I can even swap the
style sheet on the fly to change thematics without having to post anything
back.  Carving up the data into the tiles allowed for caching of the point
data too since the bounding box of each tile is consistent just like with a
WMS.  On the database side, it returns clustered points with css styles as
KML.  I never have gotten around to cleaning up the code or getting it to be
generic and to the point where it was worthy of submitting back to the
community.  I only took it just as far as I needed for what I was doing.  If
someone else could benefit from it and be able to finish it up, I'd of
course be more than willing to send it.

Subject: [OpenLayers-Users] need to internet event on vector layer before
	features are rendered
Message-ID: <1283367685586-5488396.post@n2.nabble.com>


I am trying to figure out a way to intercept an event which causes the
rendering of the features on a vector layer.

Basically I need to modify line features before they are rendered but after
a zoom has been requested.

So I registered the moveend event on the layer with my line features, which
works fine except that the lines are already rendered when I get the moveend
event. (I am trying to hide/unhide a few line features when zooming
in/out...)

Is there an event I can register for that is sent when a zoom has been
requested but before the features are rendered?

This is driving me bonkers... ;-)

Regards
Olaf

Message-ID: <1283368117008-5488414.post@n2.nabble.com>


Hello,
I'm a quite new user to openlayers, so there must be a lot of things I don't
understand...
I tried to convert between coordinates in pixels of the position of the
mouse, over a map.
I tried this 
http://carriernicolas.open-web.fr/ressources/essais_de_code/openlayers_test.html
little piece of code  but I don't understand the values that get displayed.
Is there an additional I must do in order to obtain the right latitude and
longitude ?

Thank you,
Regards,
Nicolas

I tried that sort of conversion :
                var point = map.getLonLatFromPixel(position);
		locDisp.innerHTML = (point.lat / 40000000 * 360 ).toFixed(4)+ ', ' +
(point.lon / 40065035.535 * 180).toFixed(4);
which seem to give results  in the good ranges.
But is it really the good way of conversion ? And why the latitude and
longitude would be given in meters ? Isn't it weird ? Have I missed
something ?

Thank you !

I couldn't find OpenLayers.Layer.OSM in the API docs, but the  
coordinates on your sample look like they're in 'spherical mercator',  
which is common for WMS providers like Google, Yahoo, etc.  http://docs.openlayers.org/library/spherical_mercator.html 
  says that OSM is indeed spherical mercator.

So, I think you're getting x & y values in the coordinate system of  
your base layer.  I think the values are actually a number of meters  
north & east of 0.  You can translate that to EPSG:4326 (lat/lon)  
using a function described in this page
http://dev.openlayers.org/releases/OpenLayers-2.9.1/doc/apidocs/files/OpenLayers/Layer/SphericalMercator-js.html

Also take a look at the re-projection examples on the  
spherical_mercator.html page I linked to above.

dear BMcBride and RFeagin,
If you send me your works I'll give them a try!!
Actually I've managed creating a geojson object from the php page that
executes the query.
The geojson featurecollection is echoed inside the main page so I have it
inside the openlayers <script></script>
I know it's not a optimum solution but actually it works and I can show it
to the boss! So now I'm keeping it and I'll improve it in the future.

if you want on next monday I can send or post here the solution I've found
but, since I know it's horrible, you have to promise me you won't laugh at
it ;-)

thank you

alberto

This page may help if you're using a vector layer: http://docs.openlayers.org/library/feature_styling.html

Subject: [OpenLayers-Users] maxExtent not passed to an OSM layer
Message-ID: <4C7EBA7E.50901@boreal-is.com>

  Hi All,

The maxExtent map option doesn't seem to be carried over to an XYZ type 
of layer.  Looking at the initialize function of an XYZ layer, I see the 
maxExtent is hardcoded whereas it is not in e.g. a Google type.  Why is 
that so ?  The difference in behaviour means we can't use a maxExtent 
with OSM as a base layer : it just doesn't zoom in.  Works with Bing, 
Google or Yahoo though.  But I want OSM as my base layer ...

Pointers appreciated,

Yves

OSM tile grid is (like all of our other existing layers) based on the maxExtent
of the layer. Changing the maxExtent would change the extent of the tiles, and
then nothing would line up. 

If you are interested in changing this, check out:

  http://trac.openlayers.org/ticket/2741

Which has some code and discussion of the issue.
