[postgis-users] How can I make geo-reference

[Amrita p]

Thanks for ur reply.
But I didn't get your point.

My point is - I have shape file but it contains geometry in meters form. I want to convert it into lat/log format.

I am using openmap as front end and in front end we can display only that shape file which is lat/log format.

Any idea abt this..

regards,
Amrita
