Digital Geographic Exchange Standard
The NATO Standardization Agreement 7074, Digital Geographic Information Exchange Standard (DIGEST), is a product of Defence Geospatial Information Working Group (DGIWG). This standard is related to a number of other international standards and form a model for exchange of Geographic Information. DGIWG continue to work on interoperability standards for geographic data exchange between various military systems and Geographic information system in general. However, after revision 2.1 of DIGEST, released in September 2000, the DGIWG has discontinued work on the standard and is currently focusing on incorporating its standards as profiles in ISO/TC 211.
