L3Harris Geospatial is a leading provider for a wide range of DEMs that provides coverage of every area on the Earth. Both DSMs and DTMs are available at a variety of resolutions. A DSM includes features such as vegetation and man-made structures, while a DTM will have the surface features removed so it represents bare earth.

For areas of the world with insufficient levels of resolution, we have the capability and expertise to create custom elevation data applications. We are also partnered with public and private vendors who are creating new datasets worldwide.

How the World Was Meant to Be Seen



We efficiently collect and deliver LiDAR data that easily exceed USGS quality level 1 (>8 points per square meter) requirements. In fact, data from a single flight can be produced at multiple resolutions, between 2-30 points per meter (PPM), and can be used to support numerous stakeholders and a variety of applications, providing greater value to customers.

The National Elevation Dataset (NED) is a seamless mosaic of best-available USGS elevation data. Full coverage exists in 10-meter and 30-meter resolution for the conterminous United States. The new LiDAR-derived NED at 3-meter resolution is rapidly being produced for the full country and US territories and protectorates as well.

The 7.5-minute elevation data for the conterminous United States is the primary initial source source data for the 10- and 30-meter data. In addition to the availability of complete 7.5-minute data, efficient processing methods were developed to filter production artifacts in the existing data, convert to the NAD83 datum, edge-match, and fill slivers of missing data at the quadrangle seams. One of the results of the NED processing is a much improved base of elevation data for calculating slope and hydrologic derivatives.

MapMart offers DEMs in the following formats: USGS DEM, Vertical Mapper GRD, DXF Mesh, Point and 3D Face, GeoTIFF, ASCII XYZ, RockWorks, Terragen, Surfer Grid (Binary or ASCII) and others. Some of these formats are available for immediate download by seamless custom area upon submittal of credit card and others can be generated at additional cost.

Geospatial elevation data set are utilized by the scientific and resource management communities for global change research, hydrologic modeling, resource monitoring, mapping, and visualization applications.

The L3Harris ImageLinks 3 arc second (approximately 90m) void filled SRTM elevation data set is composed of 14277 one degree by one degree DTED “cells” covering approximately 80% of the earth’s landmass between 60 degrees North and 56 degrees South latitudes.

Large SRTM voids were filled with 1km GTOPO while small srtm voids were interpolated. Filled voids common to multiple tiles were edge matched to ensure continuity. Horizontal and vertical accuracies match source SRTM except in void filled or interpolated regions. 3 arc second post spacing (approximately 90m).

A SPOT DEM is a digital elevation model produced by automatic correlation of stereopairs acquired by the High Resolution Stereoscopy (HRS) instrument on SPOT 5. Unlike a digital terrain model (DTM), which describes the distribution of terrain or "bare earth" heights, a DEM includes "first surface" elevations with vegetation and man-made structures. A SPOT DEM has a post spacing of one arc second or 20 meters.

With more than 100 million square kilometers already covered across 2/3 of the globe's land surfaces, SPOT DEM is the ideal solution to ensure rigorous registration of all your data.

SPOT DEMs significantly improve registration of data layers in digital mapping. They also are therefore widely used in geographic information systems (GIS) for land management and terrain modelling. Applications include: impact studies, rail and road infrastructure studies, mobile telecommunications engineering, structural geology surveys, oil exploration, erosion studies, mapping, flight simulation. A SPOTView Ortho can be draped over a SPOT DEM for a more realistic 3D view of terrain, which helps multidisciplinary teams to work more closely together.

As of September 2014, the 1 Arc second (approximately 30-meter resolution) elevation data from the Shuttle Radar Topography Mission was allowed to be released for areas outside the United States. The SRT Mission obtained elevation data on a near-global scaleto generate the first nearly complete high-resolution digital topographic database of the Earth’s topmost surfaces. SRTM consisted of a specially modified radar system that flew onboard the Space Shuttle Endeavour.
