We're trying to create a buffer polygon around another geospatial polygon,
but the distance between the original polygon and buffer polygon is greater
at the north and south poles. The buffer is like an oval. This is because
the buffer calculation ( as in Geometry.buffer() ) is not a geodetic
Question: Why would the GeometryFactory ask for a spatial reference system
ID ( 4323 for WGS84 ) if the buffer calculation is a simple cartesian
// sample code:
Polygon myCircle = geospatialCircleAroundTown;
GeometryFactory gf = new GeometryFactory(new PrecisionModel(), 4326 );
Geometry ovalAroundTown = myCircle.buffer(0.05) ;
Any thoughts on this? Can somebody recommend a better way to create a
geospatial buffer polygon?
Thanks in advance for any pointers.
