`UTMTOOL`

program provides coordinate conversion back
and forth among LAT-LON, UTM, and LAMBERT coordinate systems.
Longitudes are specified in
Except for Cray vector machines (Y-MP, C-90, T-90, J-90), inputs
are 4-byte REAL single precision (unlike the double precision
used internally by GCTP). Calculations for which precision is
important should use GCTP directly or should run on a natively
REAL*8 machine such as the Crays. (For extreme precision, it will
be necessary to use GCTP's facilities to specify a custom spheroid
for the surface of the Earth; `UTMTOOL`

uses the
GRS 1980 spheroid).

UTMTOOL 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
**kilo**meters; the latter is a distinct
(partially-supported) system, also.
