Terrain Data Analysis

Digital terrain and elevation model analysis functions, including profile, gradient, line-of-sight, and viewshed calculations

Terrain data analysis functions enable you to calculate the gradient, slope, and aspect of elevation data. You can also calculate the viewshed for a point on or above the terrain, or calculate the line-of-sight visibility between two points on or above the terrain.

Functions

`gradientm`	Gradient, slope, and aspect of data grid
`viewshed`	Visible area from point on or above terrain
`los2`	Line-of-sight visibility between two points on or above terrain

Topics

Determine and Visualize Visibility Across Terrain
You can use regular data grids of elevation data to answer questions about the mutual visibility of locations on a surface (intervisibility).
