I I received a polygon shapefile for lower Indian admin areas, admin3. The layer does not align properly with other Indian administrative boundaries, admin2, that are defined as geographic WGS84.
The strange thing is this undefined layer comes in the data frame in decimal degrees but it seems to have been projected at one point and probably defined incorrectly. I've tried to define the coordinate system using various Indian datums and spheriods with no luck.
I've attached the undefined admin3 layer as well as the defined admin2 layer.
If anyone have any advice about how this layer may be defined I'd be very appreciative.
