• Choose process
    • Computes one or more aggregation functions on a feature attribute. Functions include Count, Average, Max, Median, Min, StdDev, and Sum. (WPS DescribeProcess)

  • Process inputs
    • Input feature collection
    • Attribute on which to perform aggregation
    • An aggregate function to compute. Functions include Count, Average, Max, Median, Min, StdDev, and Sum.
    • If True computes all aggregation values in a single pass (this will defeat DBMS-specific optimizations)
  • Process outputs
    • Aggregation results (one value for each function computed)
