Requirements:

Registration to get access to MERIT DEM

File type:GeoTIFF, hdr, hdr, hdr
Data type:elevation , hazard specific data
Hazard:Flood
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.
