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 organisation, format and capture specifications to enable the exchange of seamless raster data sets, ARC Standardised Raster Products (ASRP), on a common worldwide datum. Other forms of this same basic file organisation 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.
