Elevation Data

Elevation Data

L3Harris provides access to a wide range of Digital Elevation Models (DEM) that cover every area on the Earth. Both Digital Surface Models (DSM) and Digital Terrain Models (DTM) 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, L3Harrs has the capability and expertise to create custom elevation data applications and is also partnered with public and private vendors to create new datasets worldwide.

Sometimes finding the image or data you need is easier said than done. L3Harris can help customers uncertain about what type of image is needed for a project, or if a sensor doesn’t have coverage of an area of interest. Whether it’s tasking satellite imaging technology to get it, or searching through available commercial satellite imagery, L3Harris will work with customers to deliver the right data for your project.
