geotrellis.vector.summary.polygonal
Given a polygon and a zerovalue, this function returns a function which can be used to compute aggregations
Given a polygon and a zerovalue, this function returns a function which can be used to compute aggregations
This trait provides the scaffolding necessary to generate aggregations which depend on Polygon and MultiPolygon instances.
the Geometry type against which containment and intersection checks are carried out to determine the flow of aggregation logic
the type of any data expected to be associated with G in Feature instances
the type being aggregated to through summary mergeOp calls
This trait specifies the type of operation to be carried out but *NOT* the "zero element" which determines the beginning value for a chain of operations (like the starting element in a fold) and *NOT* the Polygon or MultiPolygon to be used during a summary. Instead, those are specified in a call to mergeOp which returns the function used in an actual summarization.
