Overview of MERIT 90m DEM
The MERIT 90m DEM, developed by the University of Tokyo, is a high-precision digital elevation model (DEM) dataset that provides detailed topographic information. It corrects various error components from existing spaceborne DEMs such as SRTM3 v2.1 and AW3D-30m v1, offering a terrain elevation representation at a 3-second resolution, approximately 90 meters at the equator. The coverage extends from 90°N to 60°S, with reference to the EGM96 geoid.
