Re: contour mapping

Hi Nelson,

extract from wintopo webpage
http://www.wintopo.com

WinTopo Pro produces colour vectors from a colour raster

WinTopo Pro can load TIFF, GIF, JPEG and BMP raster files.

Choose colour for digitising new polylines.
Elevations (Z coordinates) can be assigned to the vectors, ready for
output to 3D CAD and GIS systems.

Output to the following format:
AutoCAD Drawing Interchange Format (*.DXF).

I think program like Deskart

may also be able to do the job.
