Agile Array Analytics

rasdaman visitors:

We focus on Array Databases, a research field we have pioneered: flexible, scalable services on large, multi-dimensional arrays, such as spatio-temporal sensor, image, simulation output, and statistics data. We address this field in all its as­pects, such as algebraic modelling, query languages, architectures, optimization, parallelization, distribution, new hardware, application, and standardization.

Applications are manifold: Earth, Space, and Life sciences, engineering and simulation, statistics, and business. All these domains suffer from "Big Data": as they are too big to transport them to the place they are needed, intelligent interfaces are required so that the desired results can be processed in place, on the server.

Among the highlights of our research and standardization activities are:

  • the free, open-source rasdaman array analytics server [more]
  • Big Data standards [more]:
    • several geo service standards, such as the WCPS geo-raster processing language; see OGC coverage standards showcase illustrating n-D geo raster services based on OGC standards (running rasdaman).
    • ISO 9075 SQL Part 15: MDA, the forthcoming extension of the SQL query language with multi-dimensional arrays, has been initiated and is being developing by our group.
  • the 1-hour TV documentary "Big Earth Data" [more]

This work has been recognized by a series of awards, such as the Copernicus Masters Big Data challenge winner and the OGC Kenneth D. Gardels award.

 

The rasdaman Array DBMS

The free, open-source rasdaman ("raster data manager") is the leading Array Database system. Effectively, rasdaman has pioneered this research field. Rasdaman is mature and heavily used by data centers internationally, with data holdings up to (currently) 132 TB. Single queries have been successfully parallelized over 1,000+ cloud nodes.

Big Earth Data - The Film

We have initiated and co-produced the TV documentary "Big Earth Data", together with German TV stations ZDF and ARTE and supported by the European Commission during the EarthServer project. See the low-resolution trailer (we are not allowed to publish the film before TV broadcasting).

Copernicus Masters: Winner, Big Data Challenge [press release]
On October 23, 2014 the rasdaman team is announced winner of the Big Data Challenge of the Copernicus Masters Earth Monitoring Competition. T-Systems International GmbH has awarded the prize to rasdaman as best Copernicus service that makes use of big data analytics technologies to provide Earth observation intelligence on demand via a user-oriented web portal and mobile devices (right: award gets handed out to Peter Baumann (middle) by Thorsten Rudolph Anwendungszentrum GmbH Oberpfaffenhofen (left) and Markus Lennartz, Vice President Global Accounts / International Business, Public Sector, T-Systems International GmbH (right)).
OGC Kenneth Gardels Award [press release]
On September 17, 2014 Peter Baumann receives OGC's prestigious 2014 Kenneth Gardels Award. From the laudatio: We wish to express our deep appreciation for the extraordinary contribution you have made to the OGC community and to people around the world who are the ultimate beneficiaries of improvements in the development, management and use of geoscientific data. Devoting your time and bringing your dedication, expertise, critical thinking and leadership to OGC working groups has resulted in significant and enduring advances in technical standards. The value you've created has been leveraged, and the OGC's work overall has been leveraged, through your active participation in other standards bodies, expert groups, councils and commissions. We thank you for this collaborative work, for it benefits us all.
