A collection of functions for calculating the upslope area and related measurements for a digital elevation model (DEM).
Based on the method of Tarboton.

See also the upslope area postings on my image processing blog, March-August 2007, http://blogs.mathworks.com/steve.

Requires Image Processing Toolbox.

Functions include dem_flow, dependence_map, facet_flow, fill_sinks, flow_matrix, influence_map, pixel_flow, postprocess_plateaus, upslope_area, vis_dem_flow, and vis_map.

Includes a sample DEM data set.
