Using Arcscene 10.1
I have an SRTM tile and have selected an area of interest. (using the AOI button and hitting enter.)
This crops the SRTM to the area that I need.
However, when i try and create contours (Spatial analysis>Surface>Contour) it created contours for the whole tile and nothing happens when I try and use the AOI tool.
Any suggestions as to why?
Thanks
Sam
