[geos-devel] Writing a wrapper around LibGEOS

[Martin Davis]

As others have said on this thread, adding curve support to GEOS is likely
to be a big effort.

My opinion is that to consider an extension of this magnitude, there needs
to be evidence that this initiative is feasible and sustainable over the
long term (at least 10 years). A good way to demonstrate this is a separate
project that extends GEOS with support for representing curves, and
implementing a *significant* set of *native* operations on curves.  That
project should have at least two developers contributing algorithmic code
to it, to show that there is ability and desire to maintain such complex
code over the long term.
