>Santosh,
>this is the German Natinal Grid projection.
>The GK system is a transverse mercator with 3°-zones (similar to the UTM
>system, which has 6° zones). Northing values are meters referring to the
>equator, Eastings are meters referring to the central meridian of the zone
>plus the zone number als first digit. There IS a false Easting, which is
>always 500000 m for the central meridian. Thus, your data are from zone 3
>(first digit in Easting).
>In ArcView, you cannot specify datums, but if you want to specify your
>projection when transforming your data to decimal degrees or other, use the
>following specifications:
>Projection: Transverse Mercator
>Spheroid: Bessel
>central meridian: 9 (9° East is the central meridian for zone 3)
>reference latitude: 0 (Equator)
>Scale factor: 1
>False Easting 3500000 (500000 m plus zone number)
>False Northing: 0
>
>Hope this works for you. Good luck,
