Desktop Exploration of Remote Terrain
Desktop Exploration of Remote Terrain (DERT) is a software tool for exploring large Digital Terrain Models (DTM) in 3D. It aids in understanding topography and spatial relationships of terrain features, as well as performing simple analysis tasks relevant to the planetary science community.
DERT was developed by the Autonomous Systems and Robotics Area of the Intelligent Systems Division at NASA Ames Research Center. It leverages techniques implemented for science planning support applications provided to a number of NASA missions including Phoenix Mars Lander (PML) and Mars Science Laboratory (MSL).
DERT was funded by the Mars Reconnaissance Orbiter (MRO) mission and developed in collaboration with members of the MRO Context Camera (CTX) science team. DERT is licensed under the NASA Open Source Agreement (NOSA).
See demonstrations of DERT here.
Prebuilt releases are available on the releases tab for this site. Additionally, versions that include the JPL SPICE kernels as well as some prebuilt landscapes are available here. These releases are built with the Java 1.8 JDK so the corresponding JRE is required to run them.
