Sorry for not being more explicit, but yes, a translation of the
Polish text with the above PASCAL file into English would be greatly
appreciated. The other korekty65.doc file would also be of interest
IF the material is reliable and if the one table it contains represents
"official" geographic<->grid conversion. Because the latter file is
very long, perhaps a summary of pertinent parts could be made.
I had ventured into the subject of the Polish grid systems about
a year ago but I was frustrated by *very* little source material in
English and no "benchmark" values---geographic<->grid conversions---
that I could rely upon for verification of projection code.
Relating to an earlier reference to the 'stere" projection I suggest
that it only be tried on applications that are influenced by the US.
Projection 'sterea' or the "double stereographic" seems to be
the most commonly employed in non-US applications. I am still
not clear on how Roussilhe relates to this problem. But more on
Thank-you in advance for any translations.
