Hello Christian, Without seeing a code snippet to understand what you are doing at the moment it's hard to say what the problem is.
Are you using the GeoTools vector to raster methods ? In GeoTools 2.7.x this is the VectorToRasterProcess class which can deal with point features: http://docs.geotools.org/stable/javadocs/org/geotools/process/raster/VectorToRasterProcess.html (In GeoTools version 8 the class name is the same but for some reason it isn't included in the online javadocs) If you have coded your own method you might like to compare it to how VectorToRasterProcess handles point features. Otherwise, please get back to the ilst with more information. Michael On 13 October 2011 04:04, Christian Sanelli <[email protected]> wrote: > Hello.
