Big Geo Data, their characteristics, variations, and new qualities (in particular, temporal aspects) are discussed in this workshop. OGC WCS and further standards will be in the center. Both concepts and their high-performance implementation will be addressed (rasdaman, MapServer, GDAL, etc.). Participants can execute many of the examples shown on their laptop, giving hands-on experience in standards-based access to Big Data. This will enable participants to pursue own research, make informed decisions on standards and tools, and elaborate Big Data solutions. The presenter is editor of the WCS standards and chair of the main Big Data relevant working groups in OGC. His group is contributing the WCS conformance tests and the WCS Core Reference Implementation, rasdaman.
