<DIV style="FONT: 10pt arial"><B>Subject:</B> [Proj] How to Reengineering the
cs2cs tool</DIV>
<DIV><BR></DIV>Dear
Friends,<BR> I am very
newbie to projection concepts. I am in need to write the cs2cs tool in
php/perl language to convert the coordinates from source epsg-2393 to target
epsg-4326. Initially i tried to understand the cs2cs tool code. I can't
understand the whole structure of the code , as it contains more mathematical
functions. So i have started to trace the code linebyline using anjuta
debugger. But i dont think this one is the correct way. As the code contains
more 'if' checks i may miss some flow of the code.<BR><BR> Please
give some guide lines to understand the concept of cs2cs tool. Where can i get
the direct mathematic formulas? So i can directly code it on php or perl
without looking the C code.<BR><BR>Thanks in Advance,<BR>Bala<BR><BR>
<P>
