converting a paper contour map to a digital 3D image



Hi all,

I asked about this sometime ago but did not get a reply.

perhaps it is too difficult to do.

What I was after was a way to take a contour plot of a terrain (or any thing fro that matter) and convert the contour intervals and positions into a digital x,y, z type data set for use in a 3D visualization program.

Any ideas?

Something along the lines of data thief or its successors would be ideal. ie be able to follow a selected contour and generate a set of xy points that related to it.

I suspect that it would be tough to do something like that in a completely automatic sense but maybe...

Any help would be appreciated.

Thanks very much.

tony
