MERIT DEM a high accuracy global DEM at 3 arc second resolution (~90 m at the equator) produced by eliminating major error components from existing DEMs (NASA SRTM3 DEM, JAXA AW3D DEM, Viewfinder Panoramas DEM). MERIT DEM separates absolute bias, stripe noise, speckle noise and …
MERIT Hydro is a new global flow direction map at 3 arc-second resolution (~90 m at the equator) derived from the version 1.0.3 of the MERIT DEM elevation data and water body datasets (G1WBM, GSWO and OpenStreetMap). MERIT Hydro contains the output of a new …

It was created by removing errors from existing DEMs. MERIT Hydro, derived from MERIT DEM, is a global flow direction map, also at 3 arc-second resolution, that uses water body datasets. Supplementary visualization layers for MERIT Hydro are also available. The main actions include the creation of these datasets and the enhancement of resolution and correction of errors.\n"]]
