turf-aggregate

build status

turf aggregate module

turf.aggregate(polygons, points, aggregations)

Calculates a series of aggregations for a set of Point|points within a set of Polygon|polygons. Sum, average, count, min, max, and deviation are supported.

Parameters

parameter type description
polygons FeatureCollection.<Polygon> polygons with values on which to aggregate
points FeatureCollection.<Point> points to be aggregated
aggregations Array an array of aggregation objects
