SRTM HGT 🏔

SRTM HGT Elevation Tile

Open Beta
.hgt · application/vnd.srtm-hgt

HGT is NASA's native SRTM elevation format: a raw array of 16-bit signed big-endian integers, a 1°×1° tile (1201×1201 for SRTM3 or 3601×3601 for SRTM1), no header, with the filename encoding the south-west corner (e.g. N55E037.hgt). On osm2cdr the HGT export works honestly like this: if the project contains a DEM raster layer, elevations are sampled from it on a grid; if no DEM layer is present, a FLAT placeholder tile with uniform height is written. No built-in SRTM source is bundled into HGT, so real relief appears only when an elevation layer is supplied. The file is read by GDAL, QGIS, OsmAnd, Locus Map.
