This functor creates a 2D coordinate spatial index from a table of point properties.
| Name | Type | Description |
|---|---|---|
| Point Properties | Table Type | Table of point properties mapping each point's id to its 2D coordinates, in the format “Point_Id*:real, Point_Y:real, Point_X:real”. Point_Y and Point_X hold the Y and X components of each point's location; the unit is arbitrary, and any Cartesian coordinate system can be used. |
None.

| Spatial Index | Spatial Index 2D Point Type | 2D coordinate spatial index created from Point Properties. |
The spatial index represents the spatial organization of the points in the 2D plane, letting other functors query the relative position of points.
