SIGDEM -- Scaled Integer Gridded DEM
.. shortname:: SIGDEM
.. versionadded:: 2.4
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.
