scope:

Digital Geographic Information (DGI) has evolved into one of the primary and most essential elements of many information system applications both for the Mapping, Charting and Geodesy (MC&G) Community and for other, diverse users. This document provides the necessary data structure, file organization, format and capture specifications to enable the exchange of seamless raster data sets, UTM/UPS Standardized Raster Products (USRP), on a common world-wide datum. Other forms of this same basic file organization and format have been created to enable the exchange of other types of MC&G raster data not explicitly for use in a seamless data sets.
