The Digital Geographic Information Exchange Standard is produced under authority of NATO’s Digital Geographic Information Working Group. DIGEST is a standard for digital geographic information which will enable interoperability and compatibility among national and multinational systems and users. DIGEST is composed of standards for two digital geographic formats: ARC Standard Raster Graphic (ASRG) and vector relational format (VRF). ASRG is very similar to ADRG and can be imported into ArcInfo as an ADRG file with the ADRGGRID command. The ArcInfo VPFIMPORT and VPFEXPORT convertors will process the VRF data.
