Making the web and easy to use geospatial computing platform
• Access to geodata on the web has become routine
– Using OGC standards based on IETF and W3C
• Geoprocessing services on the web next
– Processing to apply or fuse data to meet specific applications.
• OGC Web Processing Service (WPS) standard.
– WPS profiles for classes of algorithms
• Brings geoprocessing to the cyberinfrastructure.
– Examples of WPS from GEOSS

Geo-Processing in Cyberinfrastructure:Making the web and easy to use geospatial computing platform
• Meeting user expectations for access and processing of Earth Observation data using open standards.
• The OGC Web Processing Service (WPS) for interoperable access to hundreds of geo-algorithms
– www.opengeospatial.org/standards
• Use of cyberinfrastructure standards for access and geoprocessing vital to achieving the vision of GEOSS.
– GEO Pioneers making vast amounts of Earth Observation data for solving difficult problems in the Societal Benefit Areas.
– Contributions from hundreds of organizations for substantial achievements, cross-cutting all Societal Benefit Areas.
