The Digital Geographic Information Working Group (DGIWG) has been working since 1983 to develop an exchange standard for Digital Geographic Information (DGI). The result of this effort is the DGI Exchange Standard, or DIGEST, which specifies the exchange structure and feature attribute coding scheme for vector, raster, and matrix data. The- paper provides background information on the DGIWG, current implementation of DIGEST-compliant datasets and future activities.
