Proj Pascal bindings
Besides Pascal bindings for GDAL, I also have Pascal bindings for Proj.4 — a library for working with coordinate reference systems.
But while in the case of GDAL there were no Pascal bindings at all, the situation with Proj.4 is much more complicated. There are Pascal modules for old Proj versions 4.4.3, 4.4.6 and 4.4.7 (by Alexander Weidauer), which I used as a starting point for my work. The FPC also has a built-in package (based on the newer Proj 4.6.1). Unfortunately, I found out about this package after I had written my module.
So now I’m asking myself, should I make my code public or not?
