# GEDTM30
2 of 2 global 30 m Cloud-Optimized GeoTIFF terrain tiles, validated (CRS, nodata, pixel dimensions, elevation range via windowed reads) and indexed. Terrain derivative generation (slope/aspect/ruggedness) is left to downstream use of the COGs directly, per the source's own tiled workflow design.
