[Geoserver-users] Problems with Geotiff Coverage

GeoServer GeoServer User
1

I have some problems in visualizing a Geotiff coverage using WMS Post (GeoServer 1.5.3):

The raster is correctly returned using a get request, like this one:

http://localhost:8080/geoserver/wms?bbox=2318600.0,4852200.0,2325920.0,4858400.0&styles=&Format=image/png&request=GetMap&layers=topp:test&width=800&height=635&srs=EPSG:3004#

using a WMS POST request like the following one, I get a blank image:

<GetMap xmlns:xlink="http://www.w3.org/1999/xlink&quot; xmlns:gml="http://www.opengis.net/gml&quot; service="WMS" xmlns:topp="http://www.openplans.org/topp&quot; version="1.3.0">

EPSG:3004 is the native CRS for the Geotiff file. Is there anything wrong in my request or are there any difference from WMS get and post using coverages?

Thanks,

Hi Mauro,
try changing your POST request as follows:

EPSG:3004

Sorry my mistake … the previous is valid only for WCS POST requests … I will inspect deeper why WMS one doesn’t work!

The problem should be on the UserStyle definition … try first commenting out the UserStyle node and see what happens. It should render your image using the default style associated to the coverage.

It seems that the problem is in the tag. If I specify Feature (as in the raster.sld style) everithing is ok, if instead I use test, as I usually do with other features, I get a blank result. Is this the correct behaviour, or is there any bug causing this?

Thanks,
Mauro

On a WFS GetFeature call, is it possible to return all attributes of a feature except the geometry? I want to fetch a features informational attributes but I'm not interested in the geometry.
Thanks, David Robison

I don't know if there's a way to say "give me all fields EXCEPT the_geom"
but you can ask for only the fields you want using 'PropertyName=', like
this:

/wfs?request=GetFeature&typeName=myFeature&PropertyName=field1,field2,field7
etc

Is it possible to construct a WFS GetFeature call that would return a feature that contains a point? Thanks, David Robison

It seems the question is - which feature (if any) does my point fall inside?
I think this sample WFS request answers it:
http://lyceum.massgis.state.ma.us/wiki/doku.php?id=wfs:contains&s=wfs
Given a point and a datalayer (here towns) it returns the town that the
point falls in.
(The point is in the same projection as the datalayer).
