I'm trying to create a DEM from this raster map:

enter image description here

I managed to clean all the shapes and text. I tried to write a program which finds the curve pieces and connects them. But, I realized that it is not simple. Is there a program which takes this raster map and gives me DEM. I want to create a 3D model of this terrain.

  • You chose a complex task to handle. If it is a "real" area you might use free and available DEMs; depand on the resolution you need. See this thread – dof1985 Mar 30 '15 at 9:05
  • This is a real area but it is in Turkey. I couldn't find a detailed topo map or DEM. This is an archeological site, Sagalassos. The researchers didn't reply to my emails. I just wanted to start a fun project of making a 3d reconstruction of the site. – gokhan Mar 30 '15 at 17:25
  • The thread I attached deals with Scotland, but the data is global. If it is for fun project I suggest to use free data. i.e. ASTER DEM is 30 meters spatial resolution and +/- 20 meters in altitude. – dof1985 Mar 30 '15 at 20:25
  • Thanks for commenting. The area is 1200m x 1200m. So, I feel that 30m spatial resolution is a bit low. I will model buildings and streets. If I can complete it, the resolution will be 2m. – gokhan Mar 30 '15 at 21:38
  • hard task, and not sure about accuracy. Good Luck – dof1985 Mar 30 '15 at 23:04

I made vectorization of countours few years ago in ArcMap. There is ArcScan toolbar when I did it. Vectorization, of course, wasn't hundred per cent. You have to then manually edit some lines.

In ArcScan toolbar I used Generate Features Inside Area. You can try it if you want.
