Innovators at NASA's Johnson Space Center have developed a software suite that produces data products containing surface shape, reflectivity, and geomorphology for a desired planetary surface. The Digital Elevation Model Maker (DEMmaker) suite produces seamless sets of digital elevation models (DEMs) at virtually any resolution or size to provide the desired levels of terrain feature detail as a spacecraft approaches a planetary surface. The innovation enables researchers to study a wide variety of problem domains, as the DEMs incorporate observed data as well as mathematical models of planet morphology. Designed to model the lunar surface, DEMmaker can generate and export terrain models for a wide range of simulation, analysis, and visualization environments. In addition, the integration of new statistical terrain feature models, available reconnaissance DEMs, and control networks enhance its potential value.
- Innovative: Produces sets of DEMs based on the best available planetary reconnaissance data
- High-performance: Supports high-fidelity simulations and engineering assessments of the performance of terrain relative navigation and hazard detection sensors and algorithms
- High-resolution: Supports the rendering of shaded synthetic camera views and out-the-window vistas with realistic or arbitrary lighting conditions
- Flexible: Enables researchers to study a wide variety of problem domains by incorporating real, observed data as well as mathematical models of lunar morphology based on scientific research
- Proven: Evaluates NASA's Autonomous Landing and Hazard Avoidance Technology (ALHAT) system performance within high fidelity environments
- Organizations interested in the design, analysis, simulation, and visualization activities for terrain relative navigation, hazard detection, and surface system technologies for both terrestrial and planetary applications
