Short Description
 |
| Close-up view of the MERIT DEM and the Original SRTM DEM, for the Mekong Delta and the Amazon Floodplain. Improvement by removing stripe noise, speckle noise, absolute bias, and tree height bias can be recognized. |
Statement: The MERIT DEM was developed by removing multiple error components from existing spaceborne DEMs (SRTM3 and AW3D)
Abstract: 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 and AW3D). It represents the terrain elevations at a 3sec resolution (~90m at the equator), and covers land areas between 90N-60S. The data is freely available for research and education purpose.
