Innovation

 EarthServer has contributed several key innovations towards the vision of barrier-free "mix & match" access to multi-source, any-size coverage data -- in short: "Big Earth Data Analytics" -- based on the open standards of OGC WCPS (aka "XQuery on raster data") and W3C XQuery. EarthServer combines both into a tight data/metadata integration.

The common service platform is the rasdaman technology, which - according to core experts in the field - is the leading Array Database technology currently available.

Database query languages serve as client/server interface for "mix & match" access to multi-source, any-size, multi-dimensional spatio-temporal data - in short: "Big Earth Data Analytics" - based on the open standards of OGC and W3C. The platform technology, rasdaman, has been extended with further spatiotemporal coverage data types. Highly effective optimizations - such as parallel and distributed query processing - ensure scalability to Exabyte volumes.

Novel aspects added to rasdaman include:

  • Integrated data and metadata queries, by combining XQuery for metadata with OGC-WCPS for array queries
  • Exascale services through techniques like cloud distribution, parallelization, and SMP processing
  • Transparent queries over heterogeneous file archives and databases
  • Comprehensive OGC standards support for coverage data and services
