SFCGAL
SFCGAL supports OGC Simple Features such as points, lines, and polygons, as well as more complex 3D geometries including PolyhedralSurface, TIN (Triangulated Irregular Network), and Solid.
It implements ISO 19107:2019 and OGC Simple Features Access 1.2 standards, offering precise rational number representation for coordinates in both 2D and 3D space.
Its C and C++ APIs enable integration with spatial databases and GIS software like PostGIS and GDAL for advanced 2D and 3D computations.
- Enables complex spatial operations and analyses in PostGIS. Learn more about SFCGAL in PostGIS
- Supports advanced geometric processing in GDAL, including triangulated irregular networks (TIN) and polyhedral surfaces. See GDAL RFC 64
- Offers multiple bindings, including an official Python binding
- Utilized in a QGIS plugin: QSFCGAL
- Integration into QGIS core is under consideration for robust 3D calculations management
