[Gdal-dev] Raster to Polygon

[Christopher Condit]

At one time a few years ago there was talk of adding simple raster to
polygon functionality to GDAL (see
http://lists.maptools.org/pipermail/gdal-dev/2003-August/001037.html ).
Has that ever materialized?  Does anyone know of an alternate way to
accomplish this?  I've tried using gdal_countour, but as I expected I
just get polylines as output.  My raster images are very simple - mostly
no data values with a few regions that I need to extract to polygons.
In fact, I can even re-class to 0s and 1s if necessary.

 

Thanks!

 

Chris
