And mentioned that they came from ISO-ANSI SQL\/MM and weren&#39;t in the OGC spec. Well, lo and behold, while browsing the latest <a href=\"http:\/\/www.opengeospatial.org\/standards\/sfa\">OGC Simple Features &#8211; Part 1 spec<\/a>, the last incantation (version 1.2.1) does support &#39;em. We don&#39;t have all the OGC types (missing Curve, Surface, multi-versions of those, Polyhedral Surface, and TIN) but it&#39;s good to see the OGC support\/add the ones we do have.\n<\/p>\n<p>\nSpeaking of the new types, I&#39;m still looking for a visualizer for them. Spatial result tab was removed from SSMS CTP1 Denali, so I&#39;ve got SSMS 2008 R2 installed. But of course that doesn&#39;t support the new geometric types, so curves, fullglobe, and types greater than a hemisphere large (these were added in Denali too) draw a blank. So I can draw them on graph paper. And in my mind&#8230; Neither Bing nor Google, that I&#39;m aware of, support them. Wonder if <a href=\"http:\/\/www.safe.com\/\">SAFE FME<\/a> visualizer does, hmm&#8230; You usually approximate them with linestrings\/polygons, STCurveToLine and CurveToLineWithTolerance are your friends.\n<\/p>\n<p>\n@bobbeauch<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Once upon a time, I wrote a blog entry about CircularString, CompoundCurve, and CurvePolygon (the new geometric types supported in Denali).
