Harris Geospatial is a leading provider for a wide range of DEMs that cover every extent of the globe. 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 detail, we have the capability and expertise to create custom elevation data. We are also partnered with public and private vendors who are creating new datasets worldwide.
