PROJTOOL
program provides coordinate conversion back
and forth among LAT-LON, Lambert Conformal, UTM, Polar Stereographic,
General Transverse Mercator, Equatorial Mercator, and Albers Conic
Equal Area coordinate systems.
Longitudes are specified in signed degrees (so
that for the US, longitudes are negative); coordinate system
"UAM/EPS" means the thing with the kilometer
units instead of the UTM standard units, which are meters.
Inputs are 8-byte REAL double precision, matching the double precision used internally by GCTP. For high precision calculations, uses the I/O API SETSPHERE and SPHEREDAT package to allow the user to customize the geodetic spheroid to be used for high precision computations.
PROJTOOL also provides grid-corner calculations, assuming either a UTM-based or a Lambert-based grid, as appropriate (to get UTM or Lambert corners of a LAT-LON based grid, work one corner at a time using the coordinate conversion facilities).
NOTE: according to the standard, UTM coordinates should be specified in _meters_ instead of the UAM/EPS bastardized system which claims to be UTM but in fact uses kilometers; the latter is a distinct (partially-supported) system, also.
