The planar spatial data type, geometry, is a built-in data type in Querona. This type represents data in a Euclidean (flat) coordinate system.
The error tolerance for the geometry methods can be as large as 1.0e-7 * extents. The extents refer to the approximate maximal distance between points of the geometry object.
Querona supports the Open Geospatial Consortium (OGC) methods on geometry instances.
