Subject: RE: [emergency] Circle and Polygon
With the size and complexity of the polygons that represent jurisdictional boundaries, I fear that the GML polygon representation would become prohibitively large. Some applications are already having problems ingesting the large messages containing the simplified version for complex polygons.

I think one of the keys to the early update of CAP has been that simple concepts are represented in simple ways. Other folks may feel differently, but I'm not certain the EDXL routing application really needs the full functionality provided by this much bulkier representation. E.g., in the past we've handled included polygons... which much more often involve different information or instructions than mere exclusion... by overriding them with other blocks referencing other simple polygons. So it sounds like the TC may need to revisit the question of whether we want to follow the GML standards in full, or some other precident, or stick to a simplified model. - Art --------------------------------------------------------------------- To unsubscribe from this mail list, you must leave the OASIS TC that generates this mail.
