Digital Elevation Model Faq

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...

SimpleDEMViewer reads Digital Elevation Model (DEM) data and shows colored elevation map on a Mac screen. It can make bird's-eye views, stereographs and others. DEMs supported gtopo30, hydro1k, srtm, srtm dted, srtm30plus, etopo2, etopo5, globe, gdem some bil forms, usgs ascii DEMs, DEMs from...

The g3DGMV program was designed as a free viewer for Digital Elevation Model (DEM ) and Digital Line Graphs (DLG ) maps. Both of these formats are available from various locations on the web. These maps are rendered by g3DGMV as 3D images that can be manipulated by the user and view from...

The Strahler Stream Order is a way to classify rivers based on a hierarchy of tributaries. First-order streams don't have tributaries. When two first-order streams come together, they form a second-order stream. When two second-order streams come together, they form a third-order stream. When two...

sysshift checks whether two matrix M1 and M2 are systematically shifted against each other by calculating correlations across a range of shifted origin. This is helpful e.g. if two different digital elevation models of the same area are to be tested for systematic misregistration.At this point,...
