Quality Assessment Report Evaluates Polar Geospatial Center EarthDEM Elevation Products
NASA’s Commercial Satellite Data Acquisition program released a report evaluating the accuracy of Polar Geospatial Center’s EarthDEM elevation products. This assessment determines if these digital elevation models are suitable for use in NASA science research.
Why it matters
The results allow scientists to determine if this data meets their specific accuracy needs, offering a potentially cost-effective way to augment Earth observations.
The details
- Horizontal accuracy was graded 'Excellent' for Mosaic Tile and Strip products.
- Vertical accuracy was graded 'Basic' as it exceeded PGC's 0.5-meter specification.
- Evaluations used airborne lidar data samples from the United States and Senegal.
