Hi Srikanth,

Yes, the utility is gdal_polygonize.py. It makes vector polygons of your raster data, and the default output format is GML. You can specify any other OGR supported output format. See:
http://www.gdal.org/gdal_polygonize.html

Note - it seems that your input data must be integer, as float data will be truncated. I posted a question on this 2 days ago.

Regards,

Alan
