Abstract:

A discussion is presented of the usefulness of coordinate models for studies of geographically distributed phenomena with comments on specific coordinate systems and their relevance for the analysis and inventorying of geographical information. Appendices include equations for conversion from the Public Land Survey system into latitude and longitude and to rectangular map projection coordinates. Map projections are considered in detail, including coordinates for spherical coordinates. Statistical computations of finite distortion are related to Tissots Indicatrix as a general contribution to the analysis of map projections.
