I'm working on a magazine article for ACSM Bulliten entitled Creating
Value From Raster Data. The target audience will be land surveyors. I
was hoping some of the OSGeo guys would be able to help me with a few
questions as I do my research for the article:
- Are there any open source
Hi Landon,
- Does anyone know of research or work being done with the
development of open source algorithms and programming libraries to
enable automated feature creation from raster data?
Does it means to produce a polygon feature layer from a raster?
GDAL has this function -
One might argue that slippy maps and tile caches have added a lot of
value to raster data or at least demand.
But more directly on the topic in addition to GDAL.

More generically
Just to add what Alex mentioned already, here a link for GRASS Image
classification (how to).

Also, have a look to Orfeo ToolBox (OTB), who also has a QGIS plugin,
