Hello Bart,
I experimented with my map trying to get coordinates for EPSG:4326 from
my EPSG:32632.Map. What I did is changing the request from
http://localhost:8080/geoserver/wms?bbox=277023.0864899452,5233434.01524883,923881.7291952965,6106592.061342626&styles=&Format=application/openlayers&request=GetMap&layers=topp:Deutschland&width=457&height=550&srs=EPSG:32632
to
http://localhost:8080/geoserver/wms?bbox=*5.508,47.117,15.619,55.104*&styles=&Format=application/openlayers&request=GetMap&layers=topp:Deutschland&width=457&height=550&srs=EPSG:4326
Then I get my coordinates in Lat/Lon.
But: I didn't want to convert my 'mappicture'. It should remain in the
same UTM-projection I rectified it to. So my result is just a half step
forward.
Coordinates fine, map declined :-(
I discussed this theme in the Geoserver-List as well. There I was told
about the proj4j-library - especially about Mike Adair sandbox
(http://trac.openlayers.org/browser/sandbox/madair/lib).
This is meant to reproject coordinates from UTM (for all SRS handeling
UTM?) to EPSG:4326.
But I was was only told where to find it. So far nobody seems to have
experience with it neither knows if it's working. I also didn't find any
tutorials how to deal with it.
Do you ever met this problem?
Best regards,
cuxland

Geoserver can reproject the GeoTiff for you to EPSG:4326. This is what OL
uses by default.
So just look at the examples/wms.html and add your Geoserver URL in there.
What do you mean with retrieve coordinates? Maybe the MousePosition Control
is what you are looking for. Add that Control to your Map and you'll see the
coordinates on mouse over.
Best regards,
Bart

Onderwerp: [OpenLayers-Users] Retrieving different coordinates
Datum: 29/11/07 10:51
Hello,
I must introduce myself as a Newbie that searched a week inside this
list getting more and more confused.
I'm simply looking to an answer for this question:
I loaded a GeoTIFF to Geoserver (UTM32N/WGS84 = SRS:32632). Is it now
possible to retrieve geographic coordinates (Lat/Lon/WGS84; SRS:4326) via
OpenLayers??
Just a hint where to find more information would be very helpful.
Exhausted (from searching) greetings,
cuxland
