Elephant Meeting on Big Data Services

News Date: 
14 Dec 2015
Details: 

While we try to get to grips with the ever-increasing “Big Data” deluge we recognize that adequate Web services are a key prerequisite for ubiquitous, flexible, and fast data access. In a massive concertation effort several large European initiatives have teamed up now to address the service challenge. From 12 through 13 November 2015 an inaugural EUDAT Workshop on services for Big Data held successfully at the Super­computing Center in Barcelona, Spain. Representatives of three decisive Big Data projects - EUDAT, EarthServer, and EPOS - have come together to discuss innovative alternatives for value-adding services.

To consolidate activities around these specific themes the workshop was divided in several tracks focusing on the topics of Big Data semantics, federated Data Mining, and multi-dimensional Array Databases for large time series. Discussions started by capturing best practices and discussing the current state of development and activities in the respective areas. Questions like: How can data processing be orchestrated optimally or how can scientific workflows make use of EUDAT services were discussed intensively in different working groups.

Peter Wittenburg, scientific coordinator of the EUDAT Data Infrastructure, convened a critical variety of expertise from Europe and the US. Especially the topic of multidimensional arrays was focused by the experts because of playing a major role in scientific and engineering data. In a summary Mark van de Sanden, EUDAT Workpackage Leader, and Peter Baumann, workshop facilitator of the EUDAT Array Database track, pointed out possible roles of EUDAT in the future:

  • Iaas service provider: providing a cloud infrastructure to run Array Databases
  • SaaS service provider: providing an Array Database as an domain-independent, horizontal service
  • Providing tools for easy data movement between EUDAT DCI domain and User domain
  • Providing domain services (e.g., geo, astro, life sciences) based on a common horizontal platform of array services, thereby leveraging cross-community effects

Peter Baumann resumed his experiences of running large-scale infrastructures in his presentation:

“Of course multidimensional arrays do not stand alone, they are intertwined with other data types, but typically they constitute the “Big Data” part. Therefore, it makes sense to integrate arrays into common data management platforms.“ The flexibility of querying data, achieving data independency, scalability and standards conformance are critical advantages of Array Database technologies. Among the challenges spotted were integration of heterogeneous data types, including arrays, into a single common information space for users. Array intensive domains like the Earth-, Space- and Life Sciences were considered as possible candidates of future EUDAT services.

The following presenters contributed their expertise to the Array Database track:

  • Peter Baumann (Workshop Facilitator, Array Database expert) - Jacobs University Bremen, Germany
  • Kwo-Sen Kuo (Array Database expert) - NASA collaborator, US
  • Stefan Pröll (Data Citation expert) - SBA Research, Austria
  • Simone Mantovani (Atmospheric Analysis expert) - MEEO s.r.l., Italia
  • Alessandro Spinuso (Seismology expert) - KNMI, Netherlands
  • Luca Trani (Seismology expert) - KNMI, Netherlands
  • Thomas Zastrow (expert for Data Analysis in the Humanities) - Max Planck Gesellschaft, Rechenzentrum Garching, Germany
  • Mark van de Sanden (EUDAT Workpackage Leader) - SURFsara, Netherlands

The European Data Infrastructure EUDAT aims to contribute to the production of a Collaborative Data Infrastructure (CDI). The project´s target is to provide a pan-European solution to the challenge of data proliferation in Europe's scientific and research communities. Increasing complexity and massive growth of data has outpaced the development of tools to deal with it.

Corresponding to this challenge the intercontinental initiative EarthServer aims for unleashing the potential of Big Data through a disruptive paradigm shift in service technology. EarthServer has established open ad-hoc analytics on massive Earth Science data, based on and extending leading-edge Array Database technology, rasdaman. Now the participating data centers are extending this to a Petabyte of 3-D and 4-D datacubes. Technology advance will allow real-time scaling of such Petabyte cubes, and intercontinental fusion.

The European Plate Observing System EPOS contributes by planning a research infrastructure for European Solid Earth science, integrating existing research infrastructures to enable innovative multidisciplinary research, recently prioritized by the European Strategy Forum on Research Infrastructures ESFRI for implementation.

News Date: 
7 Dec 2015
Details: 

Geoinquietos Argentina, the OSGeo microchapter, is proud to announce the second FOSS4G-Argentina event, to be held 5 to 9 April, at the National Geographic Institute in Buenos Aires. Having such a successful initial FOSS4G event back in 2013, FOSS4G-Argentina 2016 will again bring together community leaders from all over Latin America, to share and learn about Open Source geospatial. There will be a good mix of presentations, exhibitions, and of course hands-on workshops, that makes every FOSS4G event so exciting. Mark your calendars, and come join and share and enjoy the FOSS4G spirit in Buenos Aires!

gvSIG Graduates OSGeo Incubation

News Date: 
27 Nov 2015
Details: 

OSGeo is pleased to announce that the gvSIG project has graduated from incubation and is now a full fledged OSGeo project. Manuel Madrid, a long time member of the gvSIG Project Steering Committee (PSC), has been appointed as project officer.

gvSIG

gvSIG is an Open Source desktop application designed for capturing, storing, handling, analyzing and deploying any kind of referenced geographic information in order to solve complex management and planning problems. gvSIG is known for having a user-friendly interface, being able to access the most common formats, both vector and raster ones. It features a wide range of tools for working with geographic-like information (query tools, layout creation, geoprocessing, networks, etc.), which turns gvSIG into the ideal tool for users working in the land realm.

Graduating incubation includes fulfilling requirements for open community operation, a responsible project governance model, code provenance, and general good project operation. Graduation is the OSGeo seal of approval for a project and gives potential users and the community at large an added confidence in the viability and safety of the project.

The project steering committee says, The gvSIG team is thrilled to be recognized as a full OSGeo project. There have been strong ties between the two communities with common objectives to spread open source for geomatics, and develop a business model based on collaboration and shared knowledge. We are very happy to be included as part of OSGeo and a member of such an esteemed group of projects.

OSGeo would also like to thank Dimitris Kotzinos, Jeroen Ticheler and Jorge Sanz for their assistance during this Incubation process.

Congratulations to the gvSIG community!

The OSGeo Foundation is pleased to announce that the hosting of the FOSS4G (Free and Open Source Software for Geospatial) 2017 event has been awarded by the OSGeo Conference Committee to Boston, U.S.A.

The Boston local organizing committee ("BLOC"), led by the chair Michael Terner, brings many years of experience organizing events including involvement in several past FOSS4G-NorthAmerica events. The Boston community is extremely active and vibrant, through such communities as AvidGeo, Maptime Boston, as well as the OSM community. Community members (anyone) wanting to discuss the 2017 event can do so now on the new FOSS4G2017 mailing list.

Jeff McKenna, president of OSGeo says: "The OSGeo Board of Directors are very excited for the Boston team to host the FOSS4G2017 event. Boston's so many grassroots community organizations in geospatial make it an absolutely wonderful place to bring and grow the spirit of FOSS4G. I am already looking forward to Boston 2017!"

OSGeo would also like to thank the Ottawa and Philadelphia teams for their wonderful proposals, and their continued passion for all things FOSS4G.

Congratulations to the Boston team!
