Creating Terrain Slope Maps from Digital Elevation Models in Surfer

Creating a map of slopes is common practice when looking at slope stability. Some examples of when you may want to create slope maps would be to identify areas with high slope to indicate avalanche or landslide danger. Another example may be to present slope maps of the seabed so that a structure with set tolerances for inclination could be located. Slope and gradient maps can be easily generated using Surfer.

Slope information can be easily computed from grid, raster or digital elevation models (DEMs) using options under the Grid | Calculus menu command in Surfer. The slope values can be expressed either in degrees or as a decimal (rise/run) which can then be computed as a percentage. For example, using Grid | Calculus you could select:

I wanted to add, for an example, see Surface3.srf in the Surfer Samples folder.
