WCPS for Data Aggregation
Summing Up in Space & Time.
The Use Case:
Scientists need to retrieve summary data, such as a data histogram.
Analysis-Ready Data (ARD) is not the end, but the beginning: heavy-lifting analytics needs to be done in the server, from any end device.
With WCPS, easily and efficiently aggregate data along any number of dimensions.
A histogram is just a 1-D coverage, derived from some any-dimensional coverage on the server.
WCPS histogram query creates a 256-bucket output array
where each bucket counts the number of pixels having that value, in the color band chosen.
The resulting 1-D coverage is delivered in CSV format for client-side diagram generation:
