# SIGDEM – Scaled Integer Gridded DEM

Driver short name

SIGDEM

New in version 2.4.

Driver built-in by default

This driver is built-in by default

The SIGDEM driver supports reading and writing Scaled Integer Gridded DEM files.

SIGDEM files contain exactly 1 band. The in-memory band data is stored using GDT_Float64.

SIGDEM prefers use of an EPSG ID inside the file for coordinate systems. Only if the spatial reference doesn’t have an EPSG ID will a .prj file be written or read.

NOTE: Implemented as `gdal/frmts/sigdem/sigdemdataset.cpp`.
