GEODETIC DISTANCE AND AZIMUTH COMPUTATIONS FOR LINES OVER 500 MILES

摘要

This is the third and final report of a series containing the results of a geodetic investigation of existing formulae suitable for com-puting geodetic distance and azimuth of the basic geodetic curves; the geodesic, normal section and great elliptic arc. It recommends those formulae not too complex for general use and adaptable to desk calculator and electronic digital computer. Eighteen equations were evaluated; seven for the great elliptic; seven for the geodesic and four for the normal section. The accuracy criteria for this report are set at 1:100,000 in length and one second of arc in azimuth.
