Q: How to digitize on a comfortable way isolines from a scanned map?
A:
- To get the lines in a vector map have look at: Trace vector contours from a scanned map
- Add in the attribute table a column for the height.
- Digitalize the vector map with isolated lines in the gui and update the attributes for the height.
