April, 17 -22. Highlight was the EarthServer Splinter meeting on Tuesday performed under the motto: “EarthServer – The Global Datacube Federation”. Invited representatives of international data centers arrived to get more information about the federation´s planned activities and course of actions.
For the very first time the audience could observe live demonstrations of game-changing new services by enhancing existing data archives with flexible, scalable query functionality. By establishing real-time query processing of massive 3D Sentinel timeseries and 4D weather datacubes the EarthServer initiative is making a relevant step forward contributing to GEOSS and Copernicus.
With the rasdaman Array Database System as the core technology, different spatial services impressively showed different kinds of real-time data fusion at the Splinter meeting:
- · Climate Data Service (ECMWF, UK)
In her live presentation, ECMWF data analyst Julia Wagemann contributed to data fusion of meteorological data, coming from ECMWF archives in Reading near London, with Landsat data from NCI Australia. ECMWF´s live demonstration was the first step of unleashing Petabytes of global reanalysis data in ECMWF´s MARS archive and serving it through rasdaman and the OGC datacube standards, WCS and WCPS.
- · Marine Data Service (PML, UK)
developed by PML, the Marine Data Service makes use of the ESA Ocean Colour - Climate Change Initiative data comprising a multi-sensor 15 year time series of remotely sensed ocean colour data. Oliver Clements , senior researcher at the PML Remote Sensing Group, presented the high performance service by combining oceanographic data with satellite imagery in real-time. PML plans to grow this service from over 100 TB already available to PB volumes by adding ESA Sentinel ocean color data right upon their provisioning by ESA.
- · Earth Observation Data Service (MEEO, IT) & Landsat Data Service (NCI, Australia)
Simone Mantovani, CEO of MEEO S.R.L., presented real-time data fusion by using the Earth Observation Data Service, an operational portal developed by MEEO that enables OGC standard interfaces on datacubes of geospatial data distributed across private and public Ground Segment infrastructures. The Landsat Data Service was represented by NCI Australia. The service is enabled in a high-performance computing environment, and establish a “query-the-datacube” frontend to the landsat +110 TB of data managed by NCI, exploiting rasdaman and CITE technologies.
- · Planetary Data Service
Angelo Pio Rossi, researcher at Jacobs University Bremen, presented PlanetServer, the Planetary Science Data Server of EarthServer. In his presentation the Planetary scientist who is also EarthServer Coordinator, showed the ease of processing complex data, particularly hyperspectral and topographic imaging. Data from Mars, Moon, and other Solar System Bodies got easily available. The service aims at serving and analyzing planetary data online mostly based on the OGC Web Coverage Processing Service (WCPS) datacube standard.
- · Federated Array Databases
Peter Baumann and Vlad Merticariu, both researchers at Jacobs University Bremen, presented the technology behind the EarthServer Federation as well as its state, role and contribution to GEOSS.They also highlighted the impact the rasdaman technology meantime has on standards:EarthServer utilizes the pioneer Array Database, rasdaman, for its flexible, scalable services on massive spatio-temporal datacubes, including intercontinental fusion of datacubes based on the forthcoming ISO Array SQL standard. The platform consists of the multi-parallel rasdaman array engine (Jacobs University, rasdaman GmbH), integrated data / metadata queries (CITE s.a.), and the WorldWind virtual globe (NASA).
