The generic sensor format (GSF) is a file format used for storing bathymetry data, such as that gathered by a multibeam echosounder.[1] The format was created by Scott Ferguson and Daniel A. Chayes.[2][3]
The file format specifications and C source code for a library to read and write GSF files are available from Leidos,[1] who maintain both the format specification and the source code.[3] The GSF library source code is published under the GNU Lesser General Public License, version 2.1.[3]
