Digital Elevation Model [DTM] Software/Data Sampler
A Technical Software and Data CD-ROM
Thank you for your interest in our DTM Data/Software Sampler CD-ROM. This CD-ROM contains a variety of software and digital data that is essential in the study of elevation information as it applies to geographic information system technology. The CD-ROM is divided into two sections: a software directory and a data directory.
The software section of this CD-ROM contains numerous software titles to manipulate digital elevation data. When available, source code has been included with the executable software.
- Elevation format converters allow the reformating of data from/to standard DEM, SDTS DEM, Raster-toVector, xyz, vector contours and numerous other formats.
- Elevation data viewing software allows the viewing of elevation data alone or in combination with other types of data (i.e. imagery, Digital Line Graph [DLG]). Some of the viewing software also includes a full range of format conversion functionality.
- Geodetic utilities are included that allow a full range of coordinate conversions, datum transformations, and reprojection of geographic data.
- Numerous demonstration, shareware and freeware viewers for elevation data are included on this CD-ROM.
The digital data section of this CD-ROM contains over 3 gigabytes of compressed digital data. User's manuals and other documentation is included for each type of standard data format. The following data is included on this CD-ROM:
- GTOPO30 elevation data provides worldwide coverage at a 30 arc second post spacing (approximately 1/2 nautical mile). Worldwide coverage is included on the CD-ROM.
- ETOPO5 elevation data provides worldwide coverage at a 5 arc minutes post spacing (approximately 5 nautical miles). Worldwide coverage is included on the CD-ROM.
- NAVY10 elevation data provides worldwide coverage at a 10 arc minutes post spacing (approximately 10 nautical miles). Worldwide coverage is included on the CD-ROM.
- Numerous examples of Digital Elevation Model (DEM) data at 100 meter, 30 meter, and 10 meter post spacing are included. Data is included in standard DEM, DEM SDTS, and DTED formats. Data sets over a variety of terrain classes are included.
- Numerous examples of elevation data in the form of vector contour lines, are also included. Contour line data, in a variety of formats, is included (i.e. .DXF, DLG, XYZ).
- To allow true digital terrain modeling, many example data sets of digital line graph data, digital map data, and imagery are also included. In the viewing software, these can be draped over their corresponding elevation data to create dramatic 3-D views.
The cost of this CD is $25.00 (US). This price includes shipping by first class mail in the US and Canada or airmail for international orders.
