I am having problem with projecting my counties which are in GSC_1841/Hermannskoegel to WGS_1984 in ArcGIS 9.3. I tried the basic "project" with importing the existing coordinate system but that's pretty much it and nothing happens. Somebody advised me that first I have to change the ellipsoid manually, and then do the transformation using predefined seven values/numbers. Could anyone be more specific? Thank you in advance.

EDIT: Old Yugoslavia is the country.

    it may help if you specify the country / region (former yugoslavia for example). – user17614 Aug 4 '13 at 2:01
  • Cool, I kind of figured it was in or around Serbia from the info provided. The transformation below is good. – user17614 Aug 4 '13 at 21:36

Full Ellipsoid info

Bessel ellipsoid 1841 (defined by log a and ƒ):

a = 6,377,397.155 m
ƒ = 1 / 299.1528153513233 (0.003342 773154 ± 0.000005)
b = 6,356,078.963 m.

Earth ellipsoid WGS84 (defined directly by a and ƒ):

a = 6,378,137.0 m
ƒ = 1 / 298.257223563
b = 6,356,752.30 m.

In Arcgis 9.3 the transformation code for some reason is 108264.

Let me know if you need anything else.
