This module contains functions that perform clustering on geographies.
Takes a set of points as input and partitions them into clusters using the k-means algorithm. Returns an array of tuples with the cluster index for each of the input features and the input geometry.
ARRAY<GEOGRAPHY>points to be clustered.
NULLnumberOfClusters that will be generated. If
NULLthe default value
Math.sqrt(<NUMBER OF POINTS>/2)is used.
ARRAY<STRUCT<cluster INT64, geom GEOGRAPHY>>
