[Gvsig_english] raster iamge wrong band value

[Mithoefer, Klaus]

Dear List,

I use globecover vegetation data. When I try to retrieve the band value by using the information picker or assign values to a point layer I get the wrong value (e.g. for lakes I get-46 instead of 210). I compared this with ArcGIS and FWtools.

I tried gvSIG 1.2, 1.9 and 2010 OADE with Geotif and Erdas IMG format. They all do the same. What is the problem?

Thank you,

Klaus
