Hi;
 
I am digitizing topo maps using the cumbersome tablets.
I would like to know if anybody knows about on screen digitizing using stylus
or light pen.
The idea is to use any tracing or CAD program with a scanned image in the
background and then creating an overlay digitized on screen.
 
Another request is if anybody came accross any program that converts raster
contour maps into vector format.
 
Thank u all for ur kind and helpful reply.
