DEM2GeoEG - Program to Convert USGS Digital Elevation Model (DEM) Data into a VRML File
Entry ID: DEM2GeoEG

[ Update this Record ]


Summary
Abstract: DEM2GeoEG is a program to convert USGS Digital Elevation Model (DEM) data into a VRML .wrl file that uses the GeoVRML 1.0 GeoElevationGrid. The GeoElevationGrid is a version of the standard ElevationGrid but it lets you georeference the data to geographic coordinate systems such as UTM (Universal Transverse Mercator). One benefit of this is that you can inline multiple GeoElevationGrids into a single scene and they will be correctly located with respect to each other.

Features and capabilities:

- Supports 7.5-minute USGS DEMs
- Deals with DEMs that are in feet!
- Control the number of polygons used in the GeoElevationGrid (-npolys)
- Vary the vertical exaggeration (-exag)
- Specify single/double-sided polys (-double)
- Create colour per vertex information from DEM values (-colour)
- Specify a texture map to apply to the GeoElevationGrid (-texture)
- Write out DEM as a colour, greyscale or black/white image. (-ppm, -pgm, -pbm)
- Share GeoOrigin contexts with other VRML files to merge into a single scene (-merge)
- Display human-readable description of DEM contents (-info)
- Get help on command line options if you can't remember them all (-help)
