Hi,

So far we have found a Mapinfo towgs84 definition claimed to be suitable
for Ukraine: 24,-123,-94,-0.02,0.25,0.13,1.1.

Although it yields pretty different results than the pan-Soviet Union
datum shift, I only have the word of Mapinfo authors that it is correct.

Input is WGS84 23E 49N.

Results:
former Soviet Union datum shift (28,-130,-95)
23d00'06.425689"E       49d00'01.319468"N

Mapinfo Ukrainian (24,-123,-94,-0.02,0.25,0.13,1.1)
23d00'05.992369"E       49d00'01.513576"N

Has anybody got reliable benchmarks for Ukraine WGS84->Krassovsky to
compare to by any chance?

Cheers,
Maciek
