Driver built-in by default

This driver is built-in by default

GDAL includes read support for Japanese DEM files, normally having the extension .mem. These files are a product of the Japanese Geographic Survey Institute.

These files are represented as having one 32bit floating band with elevation data. The georeferencing of the files is returned as well as the coordinate system (always lat/long on the Tokyo datum).

There is no update or creation support for this format.

NOTE: Implemented as `gdal/frmts/jdem/jdemdataset.cpp`.
