Terrain Data Analysis

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


gradientmCalculate gradient, slope, and aspect of data grid
los2Line-of-sight visibility between two points in terrain
viewshedAreas visible from point on terrain elevation grid
