Purchase Elevation Data

We provide 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, 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.


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


The possibilities for 3D mapping are infinite, ranging from wireless planning, city planning, infrastructure management, disaster management, environment monitoring, to applications in public health. AW3D has successfully established a highly capable ecosystem to provide a rich line up of 3D maps worldwide. Cost effectiveness, superior quality, fast turnaround time, and the flexibility to support a wide range of formats is what makes this all possible.
