Abstract
A growing number of scientific data archives set up Web interfaces for researchers and sometimes for the general public. While these services often deploy sophisticated search facilities, these are constrained to metadata level where conventional SQL/XML technology can be leveraged; no comparable retrieval support is available on original observation or simulation data.
For raster data in the earth sciences, this is overcome by the 2008 Open GeoSpatial Consortium (OGC) Web Coverage Processing Service (WCPS) standard. It defines a retrieval language on multi-dimensional raster data for ad-hoc navigation, extraction, aggregation, and analysis. WCPS is part of the Web Coverage Service (WCS) suite which additionally contains a simple retrieval service and a upload and update service for raster data.
In this contribution we present PetaScope, an open-source implementation of the complete WCS suite. Most of the suite’s functionality is available already, and a first code version has been released. An online showcase is being built, and the system will soon undergo real-life evaluation on mass data. After briefly introducing the WCPS language concept we discuss the architecture of the service stack based on examples publicly available on the demo website.
