Map Projections for Use with the Geographic Information System

摘要

This document has been prepared to assist users of the Geographic Information System (GIS), originally developed at the Western Energy and Land Use Team (WELUT), in understanding and using the various map projections which are available. Currently, 20 map projections may be used in the GIS. Users who have been trained in the component software systems of the GIS MOSS (Map Overlay and Statistical System), COS (Cartographic Output System), and AMS (Analytical Mapping System), and who have some introduction to principles of cartography, will find this document most helpful.
