Slope Analysis

Slope Analysis
 - To designate slope areas in Terramodel like this:



Follow these steps:

  1. You must have a DTM layer in the project.
  2. Create a new layer and make it current.
    • Example: "Slopes_0%-3%"
  3. Select DTM/DTM Slope command.
    • This command will draw plines around the triangles of a DTM that have slopes within a designated slope range
  4. Isolate the "Slope_0%-3%" layer to see what you have.
  5. Join the lines that were drawn in step 3.
    • Use the Join command - pick one line on the "Slope_0%-3%" layer, then select all the lines by layer to join them quickly.
  6. Repeat steps 2 through 5 for each slope range.
  7. Use the Draw/Hatch closed lines command to hatch areas.  When selecting the boundaries for the hatch, select the layer to create one hatch for each slope range.
