#4913 new enhancement

Add curve support to ST_AsSVG

Reported by: mdavis Owned by: stefanpetrea
Priority: medium Milestone: PostGIS Fund Me
Component: postgis Version: master
Keywords: Cc:


It should be straightforward to enhance ST_AsSVG to support curved geometries (i.e. CircularString, CompoundCurve, CurvePolygon, MultiCurve, MultiSurface). This will provide a PosstGIS-native way to visualize curved geometry, which is not widely supported by other tools.

This can be done easily using SVG elliptical arcs.

Speaking of which I have this as a TODO for X3D as well #1416. I think it would be implemented in X3d using nurbs, In particular for 2D the geometries would be expressed as Contour2D and Contour2DPolyine It's too bad we don't support 3D curves since Nurbs in X3d could handle those.
