Hi, I want to combine two raster data sets to one new in ARCGIS 10 with following condition: raster1 has two values (value, LIA), raster2 is a DTM (elevation). So the condition is: If value LIA in raster1 is < elevation in raster2, then 1, otherwise 0. I did this in ARC-Info years ago which worked without any problems, but I do not know all how to use it exactly in Arc GIS 10. To use a certain value (column) in Arc-Info we used e.g. raster1.LIA (for my data set) so Con("raster2" > "raster1.LIA", 1, Con("raster2" < "raster1.LIA", 0)) is false. Thanx in advance. Michael
