[geos-devel] Writing a wrapper around LibGEOS

[Regina Obe]

Nyall,

Thanks for the input.  I got to check out QGIS more closely with PostGIS curved geometries.  I admit to being a closeted Server/Database Admin person, not paying much attention to UIs beyond pgAdmin.  It's good to know there is so much interest in curves in the GIS community.

Thanks,
Regina
