[Qgis-user] Raster edge detection - Raster -> Vector

[Tony Shepherd (FarmMaps NZ)]

Hi All

 

Is anybody out there using any tools (QGIS or other) to automatically or
semi-automatically digitise vector data from rasters?  Roads, obvious edges
of change in land use, forestry, crops, water etc?

 

I've tried a few plugins, can't seem to get them to work very well if at all
and also a few other freebie tools external to QGIS also with mixed results,
mostly bad.  I recall many years ago seeing a really cool tool for doing
just that worked from within AutoCAD, so I am curious to see if such things
exist in the open-source / QGIS space?

 

Cheers

Tony
