Odysseus provides a wide range of functions to be used in a Map, Select, or Join operator.

The following MEP functions are not part of the Odysseus Core and may be restricted.

The spatial functions are based upon the JTS Topology Suite (http://www.vividsolutions.com/jts/JTSHome.htm).

Notice, that JTS only considers x and y coordinate and ignores the z coordinate (although z can be definied)!

Transform the list of spatial polar coordinates into a list of Cartesian coordinates

Returns the centroid of the given geometry

Creates a buffer of the given size around the given geometry

Checks whether the first geometry contains the second geometry.

Computes the smallest convex spatial polygon that contains all the points in the geometry

olygon

geometry

Transforms the given spatial polar coordinate into a spatial Cartesian coordinate.

Transforms the given spatial Cartesian coordinate into a polar coordinate
