GEOGRAPHICAL COORDINATE COMPUTATIONS. PART II. FINITE MAP PROJECTION DISTORTIONS.
MICHIGAN UNIV ANN ARBOR DEPT OF GEOGRAPHY
Pagination or Media Count:
Part I provides a discussion 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. Part II considers map projections in greater detail, including estimates of the errors introduced by the substitution of map projection coordinates for spherical coordinates. Statistical computations of finite distortion are related to Tissots Indicatrix as a general contribution to the analysis of map projections. Author
