Thanks. I was under the impression the contours weren't very good. They seem somewhat 'wonky' to me. Either way, they too so long to do. The process is as follows;
  • Create hieghtfield in Wilbur.
  • Select from height range for every 25 m.
  • Save each selection
  • Trace each image in Inkscape.


I have a folder with 89 x 95.3 MB btimaps to cover the range of 0 -> 1641 metres.

Any suggestions on a quick way to label every forth contour?
