3. Slope Input Derivation

Task 1: Create a project area slope map

  • Step 1: Open the 10 m DEM in ArcMap
  • Step 2: Generate a slope map using the "Slope Tool" (ArcToolbox under Spatial Analyst Tools -> Surface). Use the Percent option for the output measurement.
  • Step 3: Use "Extract by Mask" with your project area boundary to confine the slope map to the project area.
  • Step 4: Use the "Raster to ASCII" command to convert the .img raster to an ASCII raster format for use in MATLAB.
Your slope analysis should look something like the above.
