Abstract
Publisher Summary MicroDEM is a full-featured geographic information system (GIS), geared for geological applications with digital elevation models (DEMs). It features unique capabilities for computing terrain organization and computing regional geomorphic parameters. MicroDEM began with a heavy emphasis on practical application of DEMs, including slope maps, 3D oblique views, line of sight profiles, and viewsheds. MicroDEM reads DEMs in both geographic and rectangular (UTM-like) grids, and can read many other DEMs. A partial list of supported data formats includes: DTED, SRTM in both DTED and .hgt formats, USGS ASCII and SDTS, and netCDF. MicroDEM can create a number of statistical graphs for the DEM, either for the entire DEM or a subset currently on the screen. These choices occur on the Analyze menu, available with an active DEM map. The chapter discusses derivative terrain grids for local morphometric land-surface parameters in MicroDEM that can be created in several ways. MicroDEM can also create parameter maps for regional statistics, which require a much larger neighborhood around the point than the typical 8 neighbors used for slope, aspect, and curvature.
