Bundled with PROJ comes a set of small command line utilities. The proj +program is limited to converting between geographic and projection coordinates +within one datum. The cs2cs program operates similarly, but allows +translation between any pair of definable coordinate systems, including support +for datum transformation. The geod program provides the ability to do +geodesic (great circle) computations. gie is the program used for +regression tests in PROJ. cct, a 4D equivalent to the proj +program, performs transformation coordinate systems on a set of input points. +projinfo performs queries for geodetic objects and coordinate +operations. projsync is a tool for synchronizing PROJ datum and +transformation support data.
