Hello, ISO SQL/MM has chapters for NURBS and other magical geometry types. The text is unfortunately not free - I'd love us to have a copy for the PostGIS team at least. Last time I was touching that topic was around 2019 when I wanted to make TINs somewhat more compatible.
OGC has a very limited subset, and sometimes may contradict ISO. аў, 12 кас 2021, 01:13 карыстальнік Nyall Dawson <[email protected]> напісаў: > Hi list, > > Slightly off-topic question (but I figure the people who would know > would be subscribed to this list): > > Is anyone aware if there's been **any** talk/movement toward formally > introducing bezier and/or elliptical curve support into the SF/SQL/MM > specifications?
