[PROJ] Newbie question on projections

[Paul Ramsey]

Proj will convert double arrays of longitude/latitudes into Mollweide, if that’s the question? It’ll also convert into a whole zoo of other interesting global projections, if you’re looking for alternatives. It can be called as a library https://proj4.org/development/quickstart.html <https://proj4.org/development/quickstart.html>

The inputted data is stored in a "flat" 360x180 (scaled up or down depending upon the resolution) 2-D array. As an early step in the process I then display the map in one of the basic projections (currently Mollweide, but I would like to support others). I am hoping that I can use PROJ4 to transform this into another 2-D array that can then be passed into the display routines.
