Dear list, I have a point map in GIS format which I can import and read in ENVI as a vector *.evf file. What I want to do is to extract pixel value at every point on the vector file. In a GIS environment it would be easy using a query, but since ENVI (and other Image software) dose not have query, I still not figure out a straight way for this task. With some hybrid software like ILWIS (the one from ITC) we can rasterize a point map, then cross it with the target map to get statistic data. However switching data between several software is very time cosuming. Any idea to do this in ENVI would be very much appriciated. Anh
