SRTM Slope Calculation
Posted 20 December 2010 - 01:56 AM
I'm wondering if you can help me out at all. I'm working on calculating the slope by degree for an SRTM file.
I downloaded it from here http://ifile.it/0kbe....blogfa.com.zip
However I cannot manage to calculate the slope from it using the spatial analyst tools. If I select the output to be in degrees I get 2 attributes. And if I select the output to be in per cent I get numerous attributes for each but these figures are in the millions so obviously are not percentages.
I'd really appreciate a swift response as I'm in a massive rush, i upload picture

i transformed the data to utm project with globalmapper v.12
Downloaded SRTM tiles are in degrees (horizontal units) versus meters (vertical units). Have you transformed the data to a projected CRS with horizontal units as meters such as UTM?
but still But even when I'm working on calculating the slope, i cant manage to calculated the slop
please in software arcgis 9.3 completely ant step to step explain
thank you very much
