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 for multi-dimensional "Science SQL" and geo services on spatio-temporal datacubes [more]
  • 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 exceeding 130 TB. Single queries have been successfully parallelized over 1,000+ cloud nodes.

Big Earth Data - The Documentary

We have initiated and scientifically advised production of the TV documentary "Big Earth Data" with Gruppe 5, financed jointly by German TV stations ZDF and ARTE as well as the European Commission as part of the EarthServer project.

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.
NASA WorldWind Europe Challenge winner
During FOSS4G Europe 2014, the first pan-European open-source geo conference, the rasdaman team got awarded the crystal bull symbolizing the NASA WorldWind Europe Challenge. This annual award solicits technology worldwide that considers the INSPIRE Directive and uses NASA's open source virtual globe technology, World Wind, for providing societal benefit.
The rasdaman team has won the 2014 challenge by first-time showing an integration of the rasdaman Big Data engine with the WorldWind virtual globe while leveraging the OGC Web Coverage Processing Service (WCPS) geo query language on massive spatio-temporal datacubes. The concrete application scenario was atmospheric data analysis by determining aerosol optical properties.
