DIGEST

The Digital Geographic Information Exchange Standard (DIGEST) was

developed by the Digital Geographic Information Working Group (DGIWG)

to support efficient exchange of Digital Geographic Information among

nations, data producers, and data users.

Digital Geographic Information (or geospatial information) has evolved into an essential

element in the planning and conduct of civil and military operations. The required data volume,

demands and data complexity dictates the need for standards to assure interoperability and

compatibility. DIGEST satisfies this need by defining those aspects necessary for the exchange

of Digital Geographic/Geospatial Information such as data structures, format, feature coding

scheme, exchange media, and administrative procedures.

Over the last few years DIGEST has become the basis for co-production opportunities between

nations. DIGEST-compliant data sets are being produced and exchanged by a number of

nations to support a variety of military and civilian applications. DIGEST has become a NATO

standardization agreement (STANAG 7074). Industry continues to develop and promote

commercial software based on compliance with DIGEST.

Part 4 of DIGEST is the Feature and Attribute Coding Catalogue (FACC). FACC is a

comprehensive coding scheme for features, their attributes and attribute values.
