[gdal-dev] Buffering Right and Buffering Left Using Gdal/OGR

[Paul Meems]

Hi Pratap,

You need to use BufferParameters. Then you can set SingleSided to true.

Here's some code we use in MapWinGIS:
GEOSBufferParams_create();
GEOSBufferParams_setSingleSided();
GEOSBufferWithParams();
I'm not sure if you can use the above code, I'm not a C++ developer ;)
But it should give you some pointer were to look.

Cheers,

Paul
