<p>I was hoping to find an operational (or easily ported)
Android solution, and less of a swiss-army knife codebase. You
covered these issues in your response, and SIS / GDAL may yet
prove usefull in the eventual solution. I'm still hopeful that
there might be a simpler solution, not yet suggested (and that
I've not yet discovered).</p>

<p>No problem. I'm not sure if it has been pointed out in previous
replies, but another good source is:</p>

<p>It provides both C++ and Java implementations of the same
algorithm, and part of those C++ algorithms are actually
integrated into Proj.4.</p>
