With support of PARSEC, Mundi now follows the trend towards actionable datacubes offering analytics, visualization, and fusion service in the Mundi marketplace, linked into the EarthServer federation.
Mundi is one of the European DIAS services tasked with providing Sentinel satellite data. The Mundi Marketplace comprises a one-stop shop for Earth Observation services on top of Sentinel data and more. On these data, a value-adding service has been set up using rasdaman to offer Mundi data as datacubes on which “any query, any time, on any dimension” can be answered. PARSEC supports this activity and offers its beneficiaries access through the Big Data Toolbox.
Based on the open datacube standards of OGC, ISO, and INSPIRE Mundi datacubes by rasdaman provide flexible, simplified access and analytics on Mundi Sentinel data. A wide spectrum of clients is supported, ranging from simple map navigation (ex: OpenLayers, Leaflet) over Virtual Globes (ex: NASA WorldWind, Microsoft Cesium) and Web GIS (ex: QGIS) to high-end analytics (ex: python, R). Additionally, the OGC datacube analytics language, Web Coverage Processing Service (WCPS), is directly available; the forthcoming OGC OAPI-Coverages specification will be supported once stable.
Altogether, datacube analytics is available to experts and non-experts alike, in the comfort zone of their well-known clients. Large and small industry, authorities, and scientists alike enjoy rapid deployment and agile adaptation of rasdaman-based datacube services.
But Mundi is only a part of something larger. Mundi datacubes are seamlessly integrated with other Earth data offerings of satellite image timeseries, climate timeseries, DEMs, and manifold further thematic products. For this purpose, Mundi is part of the EarthServer federation https://earthserver.xyz/, which, based on rasdaman, offers a single, coherent, fully standards-based Earth data information space where users can freely access, analyse, and combine all data assets irrespective of their location.
Furthermore a preview version of rasdaman 10 has been released currently and pushes as well the Mundi datacube service a further step forward. The new rasdaman version will be packed with innovation and enhancements; both rasdaman community and enterprise are being advanced substantially. A sneak preview is now available with the 10beta release. Among the load of new features and improvements there is:
- a completely new query engine with substantially increased performance on modern multi-core architectures, reduced memory usage, enhanced nodata handling with null masks, and more. While rasdaman was already leading in performance, large-scale deployments show another massive speedup.
- Heterogeneous data can be combined into a single coverage. The huge asset of individual Sentinel-2 scenes, for example, comes in different UTM zones – these now appear as a single, homogeneous Sentinel-2 datacube. During retrieval, all necessary reprojections, scaling and overlaying are done on-the-fly, transparently, and in realtime.
- A catalog feature enables spatio-temporal searching and filtering of available coverages, both locally and in the federation.
- Role-Based Access Control allows administrators, through convenient Web tools, to restrict access to datacubes and parts thereof, down to single pixel level. Quota can restrict resource usage on a per-user basis.
For rasdaman community, the usual download from https://rasdaman.org applies; for customers with an active maintenance contract the rasdaman enterprise release is available on the enterprise download portal.
