# SRTMHGT -- SRTM HGT Format

Driver short name

SRTMHGT

Driver built-in by default

This driver is built-in by default

The SRTM HGT driver currently supports the reading of SRTM-3 and SRTM-1 V2 (HGT) files. The files must be named like NXXEYYY.hgt, or starting with GDAL 2.1.2, NXXEYYY[.something].hgt

Starting with GDAL 2.2, the driver can directly read .hgt.zip files provided that they are named like NXXEYYY[.something].hgt.zip and contain a NXXEYYY.hgt file. For previous versions, use /vsizip//path/to/NXXEYYY[.something].hgt.zip/NXXEYYY.hgt syntax

The driver does support creating new files, but the input data must be exactly formatted as a SRTM-3 or SRTM-1 cell. That is the size, and bounds must be appropriate for a cell.
