gCube Spatial Data Processing offers a rich array of data analytics methods via OGC Web Processing Service (WPS).

Overview

Geospatial Data Processing takes advantage of the OGC Web Processing Service (WPS) as web interface. It is implemented by relying on the gCube platform for data analytics.

Overall Architecture

Key Features
