About:
Mapx is a coordinate transformation library developed at National Snow and Ice Data Center (NSIDC). It was initially developed from equations given by Snyder (1982). Additional projections have been added as needed. The C version currently supports 11 common projections, in both spherical and ellipsoid forms when appropriate. The Java version lags behind somewhat and currently supports nine common projections, in both spherical and ellipsoid forms when appropriate.

[»] MS2GT
by Ivan Shmakov - Feb 22nd 2007 04:48:23

One of the primary uses of Mapx for me was,
until recent, the dependency of MODIS
Swath-to-Grid Toolbox (MS2GT) on it. However,
it appeared not too hard to replace `ll2cr' of
MS2GT with the `proj' filter binary from a
powerful PROJ.4 package. Indeed, you only have
to transform input data from two separate
`float' streams (latitude and longitude one) to
a mixed `double' (longitude-latitude) one, and
then vice versa for output. (You may need to
negate the resulting Y-coordinates as well,
since the Y-axis in carthography typically
points up, while in computer graphics it oftenly
points down.)

There's also a preliminary Autotools-based build system for the package at http://theory.asu.ru/~ivan/devel/autohacks.html
