I am trying to extract values from my rasters (slope, aspect, landcover etc.) for my animal group locations. I used Spatial Analyst > Extract Multi-values to Points, but when I look in my attribute table after the process the results are the same for all the points and make no sense. For example 0 for a landcover, -3x10-38 for a slope, etc.

Do you have an idea what I am doing wrong?

I am working with ArcGIS 10.

Are the points and rasters in the same coordinate system? – ccn Apr 15 '13 at 3:32
Yes they are... – Elena Spark Apr 15 '13 at 14:33
This tool has always been buggy for me. You could create a model that chains together multiple instances of the "extract value by point tool" – G-wizard Oct 28 '13 at 16:48

The tool you are looking for is the "Sample"(Spatial analyst>Extraction>Sample). Add all your rasters, then the shape file with the locations.

Thank you! Now if instead of points I have buffers of different size, can I use this tool too? I tried using GME intersect polygon/raster but I get results as if I had no values everywhere on my raster... – Elena Spark Apr 14 '13 at 18:53
