Description of 3DEM:

3DEM produces OpenGL rendered landscape scenes, flyby animations, and VRML worlds from freely available USGS Digital Elevation Model (DEM) files, USGS National Elevation Dataset (NED), Global 30 Arc Second Elevation Data Set (GTOPO30 DEM) files, Global Land One-km Base Elevation (GLOBE DEM) files, NASA Mars Orbiting Laser Altimeter (MOLA) files, or any topographic data file which is organized by rows and columns of elevation data. 3DEM produces 24 bit color 3D projections, red-blue projections requiring red-blue 3D glasses for viewing, or Liquid Crystal Shutter (LCS) projections for use with LCS 3D glasses. Completed scenes can be saved as Windows bitmaps or jpeg images for transfer to other applications. Flybys can be saved as AVI animation files. Any terrain area can also be saved as a VRML world file. Full color, high resolution VRML models can be created for any area of the world for which DEM data is available. 3DEM can merge multiple DEMs to provide high-resolution overhead maps and 3D projections of large surface areas, limited only by the computer's memory. Geographic coordinates (latitude and longitude) are shown on all overhead view map displays. Both Lat-Lon and UTM coordinates are supported, allowing display and measurement of position to high accuracy. Global Positioning System (GPS) waypoints can be read and displayed on images and flybys of the terrain, allowing you to record and display the path of a trek through the wilderness.
