# GSBG – Golden Software Binary Grid File Format

Driver short name

GSBG

Driver built-in by default

This driver is built-in by default

This is the binary (non-human-readable) version of one of the raster formats used by Golden Software products (such as the Surfer series). Like the ASCII version, this format is supported for both reading and writing (including create, delete, and copy). Currently the associated formats for color, metadata, and shapes are not supported.

Surfer 8 uses a fixed nodata value at 1.701410009187828e+38. When writing a GSBG dataset, GDAL remaps the user-specfied input nodata value to 1.701410009187828e+38.

NOTE: Implemented as `gdal/frmts/gsg/gsbgdataset.cpp`.
