[geos-devel] OverlayNG as Default

+1 for flipping the switch.

 

I don’t know what “light your hair on fair”   means :)

OK, it's been a while, and I'd like to flip over GEOS master to use OverlayNG as the engine behind

 

Geometry.intersection()

Geometry.difference()

Geometry.union()

Geometry.symdifference()

Geometry.unaryunion()

 

That will entail changing the expected outputs for a few of the regression tests, as detailed here.

Once that is done, regressions in PostGIS and other downstream projects can be #ifdef'ed around GEOS version. As seen in the document above, there actually aren't than many cases that need special handling in PostGIS, and hopefully not in other downstream projects.

 

If you have any concerns, please light your hair on fair in the next couple days.
