<div bgcolor="#FFFFFF" text="#000000" class=""><p class="">I have a project that takes spherical maps (either Terrestrial or
astronomical) as its input. 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.</p>
<ol class="">
<li class="">Is this something that PROJ4 can do?</li>
<li class="">If so, can this capability be called as a library function
from within the program?</li>
<li class="">If not, is there another library I should consider to support
this need?<br class="">

</ol><p class="">Thank you for your help with this.</p>
