![]() In order to work with DEM files you should install GDAL libraries. Rescue or agriculture applications might be interested in testing their robot behaviors using a simulated terrain that matches the real world. The main motivation to support DEMs in Gazebo is to be able to simulate a realistic terrain. Currently, Gazebo only supports raster data in the supported formats available in GDAL. In fact, the DEMs can be represented as a grid of elevations (raster) or as a vector-based triangular irregular network (TIN). The term DEM is just a generic denomination, not a specific format. Wikipedia is a good resource for getting more details about DEMs. The terrain elevations for ground positions are sampled at regularly-spaced horizontal intervals. DEMs are frequently created by using a combination of sensors, such as LIDAR, radar, or cameras. A Digital Elevation Model (DEM) is a 3D representation of a terrain's surface that does not include any objects like buildings or vegetation. ![]()
