Hi
With CAD Overlay, u can do the rubbersheeting of
Survey of India Toposheets to its LAT/ LON values. But
as u are aware, LAT/Lon are spherical co-ordinates and
u won't be getting a perfect seamless edgematcing.
Other process i can suggest u is to project it to
standard projection system of UTM / Polyconic systems.
But, u won't get a perfect seamless mosaic along the
edges.
Regards
Jay
