SAMPLE DATA
The digital elevation model for the Alma NE quadrangle is given in a number of different formats. The sample DEM file is given in zipped format to save some disk space. The USGS DEM raw file is extracted from this zip file. When unzipped, the DEM file is now in ASCII text format. A GIS software is then required to visualize this data. The map quality layout from GIS software is a nice visual tool to identify topographic characteristics of a region. ArcView v.3.2 from ESRI Inc. is used to process this sample DEM file.
