| Summary : POLYGON LOOKUP USING KD TREES
|
Description :
Facilitates efficient polygon search using kd trees. Coordinate level
spatial data can be aggregated to higher geographical identities like
census blocks, ZIP codes or police district boundaries. This process
requires mapping each point in the given data set to a particular
identity of the desired geographical hierarchy. Unless efficient data
structures are used, this can be a daunting task. The operation
point.in.polygon() from the package sp is computationally expensive.
Here, we exploit kd-trees as efficient nearest neighbor search
algorithm to dramatically reduce the effective number of polygons being
searched.
