I've not had a chance to use these, but these do what you want?


Not spatial, but may also be of interest.

Is anyone aware of a raster tracing tool for geospatial users released
under an open source license? I’m looking for something similar to:


I found the Autotrace program (http://autotrace.sourceforge.net/), but it
seems to be a little more limited, and not geared to the GIS user.
Vextractor allows you to georeference your tracing output and supports
export of the traced vectors to SHP and DXF.

The price for a single license of Vextractor isn’t bad ($99 US), but I’d
love to find a similar open source project. I’ve thought about trying to
write something up using JTS, but I know it would be a very challenging
project. I’d like to know if any of you have worked on open source projects
in this area.

Thanks for any info.
