Re: CVS GEOS union results: msg#00030

gis.geos.devel

Subject: Re: CVS GEOS union results

I am incorrect. PCL/GEOS 2.2.2 also produces a GEOMETRYCOLLECTION/MULTIPOLYGON.


Geometry A is a number of hexagons that were unioned together. Geometry B is a wedge that was created by differencing geometry A with another (border) polygon in an attempt to "fill" to the border. All of these operations were done with GEOS cvs head.

The geometry is my own, and it is not from the JTS test suite. Using Python Cartographic Library with a GEOS 2.2.2 produces a result that is more in line with the expected one (a single polygon rather than a concatenated multipolygon).

I haven't seen the geometries visually, did you ?
The default precision model is FLOATING (double), right,
but for XML tests the precision model can be specified
with the <precisionModel> tag.
