[mapserver-users] Curves in MapServer

[Basques, Bob (CI-StPaul)]

All,

We moved to storing curves in Postgres/postgis as a way of distributing to those applications/clients that can consume curves.

The Postgres loading stuff has been somewhat manually intensive in setting up, but it’s somewhat automated now.  We’re sourcing data from both AutoCAD and ESRI Features, and converting to CircularStrings in postgres.

OGR has infrastructure to convert from curve geometries to approximated curve
geometries with

geom = OGR_G_ForceTo(geom,
  OGR_GT_GetLinear(OGR_G_GetGeometryType(geom)), NULL)

as used in mapogr.cpp for example
