Spatial Geometry

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 recognizes the following source systems that support Spatial types:

Source	Native type at source
SQL Server	geometry
Oracle	sdo_geometry

Querona recognizes the following target systems for materialization of the geometry type:

Target	Materialized as type (format)
SQL Server	geometry (native geometry)
Spark	varbinary (WKB)
