Introduction and Purpose

The open format of digital terrain information is intended for use in geographic information systems for storing digital terrain information, exchanging data between various systems, creating digital vector maps, and solving applied problems.

The format was developed in 1992 by specialists of the Topographic Service of the Armed Forces of the Russian Federation and in 1993 was approved as the main exchange format for digital terrain information in the Armed Forces and a number of federal services of the Russian Federation.

Digital terrain information in the SXF format can be represented as a binary or text file.
