[eat your heart out line eater]


We're a graphics R&D shop with a requirement to display symbology
superimposed upon a map background.  This entails converting global
position data (in terms of latitude/longitude values) to screen
points and vice versa.  Does anyone know of:

    1.)  Any published algorithms for commonly-used map projections
         (e.g. Mercator, transverse Mercator, stereographic or
         Lambert conformal)? 

    2.)  Any software packages that we can adapt (we need source
         code, since future target machines can be just about
         anything)? 

    3.)  Any method to convert between Universal Transverse Mercator
         (UTM) coordinates and latitude/longitude coordinates?

Any suggestions would be greatly appreciated.

You can get the Fortran source code for a program called EZMAP from 
        Software Distribution
        Scientific Computing Division
        National Center for Atmospheric Research
        P.O. Box 3000
        Boulder, Colorado 80307

EZMAP is part of the NCAR Graphics package, which is distributed on 9
track tapes in several formats (specify character set (ASCII or
EBCDIC) and density (1600 or 6250)).  The cost for the entire
graphics package that includes many other utilities besides EZMAP,
test programs, and documentation is $300.  You can order only the
documentation first, to see if the capabilities and interface are
suitable.
