Product Name:
Elevation
Company: All Terrain Digital
We use the stereo- and triple-imaging capabilities of the 2.5 meter ALOS PRISM instrument to build high resolution 5 meter elevation grids. Our custom processing produces by far the greatest data value per dollar spent, delivering 25 times the information of a SPOT DEM at just twice the cost per square kilometer. Coverage is available over most of the world, and is increasing daily.
Product Name:
Formats
Company: All Terrain Digital
Our standard output format for elevation and surface data is a grid for use in a Geographic Information System. The grid contains elevation or surface measurement values. The data can be referenced to any coordinate system, datum, and/or projection of your choosing. The format can be any of the widely-supported binary or ASCII GIS raster formats, such as BIL, DEM, IMG, or ASCII GRID.
Product Name:
Surface
Company: All Terrain Digital
The fundamental property of the earth's surface is elevation. An elevation grid, however, contains much more information that can be computed for more specialized visualization and analysis. Surface characteristics that describe the orientation, shape, visibility, exposure, or waterflow are the basis for a wide range of applications in geology, natural hazards, ecology, energy, conservation, and more.

EVMAP Series
Company: East View Geospatial
Our flagship product, EVMAP, is a concept designed to address specific customer needs and requirements. EVMAP represents a geospatial product available in many formats, compiled from best available sources and compliant with current NGA military specifications.Product Name:
Digital Surface Models
Company: Intermap Technologies
A DSM is a topographic model of the earth's surface that can be manipulated using a computer. It is comprised of elevation measurements laid out on a grid and these measurements are derived from the return signals received by the two radar antennae on the aircraft. The signals bounce off the first surface they strike, making the DSM a representation of any object large enough to be resolved. These include buildings, vegetation, and roads, as well as natural terrain features.Product Name:
Digital Terrain Models
Company: Intermap Technologies
A DTM is a topographic model of the bare earth that can be manipulated using a computer. A DTM has had vegetation, buildings and other cultural features digitally removed, showing only the underlying terrain.
This image is achieved using TerrainFit®, our proprietary software, which derives terrain elevations based on measurements of bare ground contained in the original radar data (DSM).Product Name:
NEXTMap
Company: Intermap Technologies
NEXTMap is Intermap’s national program for mapping the terrain of whole countries in unprecedented detail. Elevation and imagery data is captured using Intermap’s high-resolution radar (IFSAR) mapping technology. The data is obtainable for areas as small as 2 sq km and available at different resolutions and price points for use with a wide variety of computer software, including CAD, GIS and modeling.Product Name:
Digital Elevation Model
Company: National Land Survey of Finland
The Digital Elevation Model describes height above sea level. It is the most accurate nationwide material on elevations. The Elevation Model is calculated from the contour lines and coastline elements of the basic map by triangulation network interpolation into a grid model where the grid cell size is 25x25 m.Product Name:

Digital Elevation Data
Company: WhiteStar
WhiteStar's Digital Elevation Data is based on the USGS National Elevation Database 30 meter grid. Elevation data are available in grid or vector form and can projected into user-specified coordinate systems, making them ideal for adding elevation contours to maps and orthophotos. Digital Elevation Models can be integrated with WhiteStar's Public Land Survey, Texas Land Survey, and Enhanced Culture Databases.
