| Data accessibility: | export data |
| Requirements: | Registration to get access to MERIT DEM |
| Data type: | elevation, hazard specific data |
| Disaster cycle phase: | Disaster Risk Management, Response, Recovery |
| Space-based Information: | The MERIT DEM was developed by removing multiple error components (absolute bias, stripe noise, speckle noise, and tree height bias) from the existing spaceborne DEMs (SRTM3 v2.1 and AW3D-30m v1). It represents the terrain elevations at a 3sec resolution (~90m at the equator), and covers land areas between 90N-60S, referenced to EGM96 geoid. |
| Spatial coverage: | Global |
| Spatial resolution: | 90m |
| Temporal coverage: | Near-real time |
