Spatial index#

GeoPandas will use the STRtree implementation provided by the Shapely (shapely.STRtree)

GeoSeries.sindex creates a spatial index, which can use the methods and properties documented below.

Constructor#

Generate the spatial index

The spatial index object returned from GeoSeries.sindex has the following methods:

`intersection`(coordinates)	Compatibility wrapper for rtree.index.Index.intersection, use `query` instead.
`is_empty`	Check if the spatial index is empty
`nearest`(geometry[, return_all, ...])	Return the nearest geometry in the tree for each input geometry in `geometry`.
`query`(geometry[, predicate, sort, distance, ...])	Return the integer indices of all combinations of each input geometry and tree geometries where the bounding box of each input geometry intersects the bounding box of a tree geometry.
`size`	Size of the spatial index
`valid_query_predicates`	Returns valid predicates for the spatial index.

The spatial index offers the full capability of shapely.STRtree.
