Abstract The Comprehensive Resource Inventory and Evaluation System (CRIES) Project uses a systematic approach in natural resource assessment and land evaluation for development planning and policy analysis. In part, this involves the creation of an operational capability within selected planning institutions to develop an integrated resource data base and analyze with custom software to the comparative advantage of resource production alternatives. For this purpose, a number of software modules were developed, including mainframe and micro computer‐based Geographic Information System (GIS) software. This paper describes the latest micro computer GIS version, namely, the Master File Creator Program (GEOMAST) and the Geographic Resource Analysis Program (GEORAP) ‐ of the Comprehensive Resource Inventory and Evaluation System (CRIES) Geographic Information System (GIS) as modified for IBM‐PC, Model XT or compatible micro‐computers using the MS‐DOS operating system. GEOMAST provides the capability to store, ...
