USGS Open-File Report 88-364: A Guide to Commonly Used Map Projections Prepared for use in HyperCard, 1988

A Guide to Commonly Used Map Projections Prepared for use in HyperCard, 1988

By Tau Rho Alpha, Joe F. Vigil, and Lauren Buchholz

Summary

This guide briefly describes and illustrates the characteristics of 17 map projections commonly used to present thematic data. By means of simple sketches of the basic grid system of longitude and latitude known as the Earth's graticule, the guide shows examples of the following categories of map projections: planes (azimuthal), cones, cylinders, and miscellaneous. The text gives examples of thematic maps published by the U.S. Geological Survey that use various projections. The guide was created as a HyperCard "stack" for use only on the Macintosh family of computers. The guide consists of descriptive material only and does not contain a program for creating map projections.
