Exploring the Moon's soils with Surfer 15's 3D viewer.

One of our Surfer 15 users Alain Paillou has been kind enough to share his work with us - he has been using Surfer's new 3D viewer to analyze the soils of the Moon. Please read on! My name is Alain Paillou, I'm a hydrogeologist and I work for the French Environment Minister. I study surface and groundwater quality in the Bourgogne Fr...

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:
