[GIS] Geoserver GetFeatureInfo WMS attributes: how to hide geometry

geoservergetfeatureinfowms

I know this has been discused before, but before somebody tell me about data base views or HTML templates, this is my concern:

Geoserver returns the geometry field from WMS getfeature info, enabling anyone to create scripts to download the data from the server as if it was WFS.

Is there a way to prevent this behaviour?

You can use the HTTP parameter "propertyName" to specify the properties that you want to be returned (comma-separated list), e.g. &propertyName=name,category. So, if you want all attributes, except for the geometry to be returned, you must include all property names in this list.

See: http://docs.geoserver.org/stable/en/user/services/wms/reference.html#getfeatureinfo for all details.

So mostly for future readers of this question - when you are doing getFeatureInfo requests to a different server (which includes a difference in the port number) you need a proxy - see http://trac.osgeo.org/openlayers/wiki/FrequentlyAskedQuestions#ProxyHost for more discussion.

GeoServer WMS – Correct WFS Wrong Coordinates for Line Features

To answer my own question and hopefully help others.

The issue was that the source data contained 3d dimensions although it is a 2dimensional geometry. At this point in time I'm not sure why this is the case.

This older link

http://lists.osgeo.org/pipermail/postgis-users/2006-March/011508.html

suggests that it might have to do with how it was exported from an ESRI environment.

Consequently the geometry type is MULTILINESTRINGM and it turns out that the WFS component of geoserver can't handle that properly although WMS works fine.

The solution was to convert the data in Postgis to 2d using

Alter table my_geotable 
    Alter Column geom TYPE geometry(MULTILINESTRING,*mySRID*)
        USING st_Force2d(geom)
