It seems Pulkovo 1942 variants are much more used, than 1932. The main difference seems to be that they changed from Bessel spheroid to to Krassowsky. Anyway, the file contains a number of coordinates given in Pulkovo 1932 (zone 5 and 6) as well as UTM89. Bernt found that these coordinates are enough to get a good approximation using linear regression. The border is going to be resurveyed next year, and hopefully a more modern daum will be used. I will post a link to the border as soon as I am done processing the numbers. Regards, Gustav ___ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk

Oooh projection archeology, it's even more fun when you go down to local county databases they all have their own projections scheme for better fit to the grid. Reading in Proj4 projection definitions file there seems to be many pulkovo zones in 1995, maybe the same is true for 1932? Calling up your local university GIS department they are usually very glad to help.. :-) You can also ask the OSM Russians: http://forum.openstreetmap.org/viewforum.php?id=21 /Emj ___ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk

Re: [OSM-talk] Anyone familiar with Pulkova 1932 coordinates?
Well, that article defines on how to transform from DHG (Deutches Heeres Gitter) Plukovo 1932 to UTM ED50 in zone 34, and that's a start. Question is, is that (DHG Pulkovo 1932) the same as the coordinates we have for the border which is described like this: Koordinatene er konforme , rettvinklete Gauss-Krugerske, etter Pulkovasystemet av 1932 (Bessels ellipsoide).? Which should translate to something like The Coordinates are conform, orthogonal Gauss-Krugerian, after the Pulkova System of 1932 (Bessel's ellipsoid) More details in Norwegian in the referenced document ;-) 2008/11/21 Tom Hughes [EMAIL PROTECTED]: Erik Johansson wrote: Oooh projection archeology, it's even more fun when you go down to local county databases they all have their own projections scheme for better fit to the grid.

I got the official coordinates for all the border stones and markers along the Norwegian-Russian border. The points are taken from the official protocol, and are in Pulkovo 1932 coordinate system. Does anyone have experience in working with this coordinate system or know how to transform the values to WGS84?
