Abstract
There are several ways to transfer data from an existing map to another map by computer. If the projection and parameters of both maps are known, analytic formulas may be used to convert rectangular coordinates of the first map to latitude and longitude and then to rectangular coordinates of the second map. This general solution, contained in a USGS computer program, involves inverse formulas for the first projection and forward formulas for the second projection.
