    3636The [http://www.gdal.org/gdal_polygonize.html gdal_polygonize.py] python script can be used to convert raster layers to polygon layers since GDAL 1.6.  It will produce very detailed polygons around each area of equal pixel value.

    40 Currently the gdal_rasterize utility cannot create a blank raster based a vector datasource although this feature has been considered (Ticket #1599).

     42Before GDAL 1.8.0, the gdal_rasterize utility cannot create a blank raster based a vector datasource although this feature has been considered (Ticket #1599). 
    4143Until that feature is added you'll need to find a way to generate a raster that matches the extent of your vector layer. You can then use that blank raster to burn in features from your vector layer.
