Thanks Chaitanya,<div><br></div><div>I like the look of that second option.

You need to do this yourselves.<br>You can get the WKT of the geometry and and edit the string. If you are willing to recompile GDAL/OGR, you can modify the code that creates the WKT. Even wrote how to do this in this mailing list [1].<br>
