====== Create Spatial Index For 2D Points ======

===== Description =====

This functor creates a 2D coordinate spatial index from a table of point properties.

===== Inputs =====

^ 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.  |

===== Optional Inputs =====

None.

===== Outputs =====

^ Name  ^ Type  ^ Description  ^
| Spatial Index  | [[Spatial Index 2D Point Type]]  | 2D coordinate spatial index created from Point Properties.  |

===== Group =====

[[Functor List#Spatial Index: 2D Points | Spatial Index: 2D Points]]

===== Notes =====

The spatial index represents the spatial organization of the points in the 2D plane, letting other functors query the relative position of points.
