Calculation of small distances

Richter, C. F.


Tables are presented which facilitate the calculation of small distances between points on the earth's surface whose latitudes and longitudes are given, for mean latitudes from 30° to 40°. The error does not exceed one-tenth of a kilometer in 500 kilometers, and may be reduced by applying specified corrections.
