Land surface topography significantly affects the processes of runoff and erosion. A system which determines slope, aspect, and curvature in both the down‐slope and across‐slope directions is developed for an altitude matrix. Also, the upslope drainage area and maximum drainage distance are determined for every point within the altitude matrix. A FORTRAN 66 program performs the analysis.
