[OSGeo-Discuss] Big Earth Data - the Documentary

2015-03-30 Thread Suchith Anand
Peter Baumann has also send excellent details of  TV documentary that he and 
colleagues in Germany developed  which addresses Big Earth Data. Details at

http://kahlua.eecs.jacobs-university.de/~lsis/Big-Earth-Data_the-ARTE-Movie/index.php

I think it is a good example of explaining in simple terms synergies with 
Geospatial and Big Data to the wider public. So let us make sure we keep 
building more ideas for joint research at Plenary 6 and the future.

Best wishes,

Suchith

Subject: Recordings and minutes of joint meeting of IG Geospatial  IG Big Data 
- RDA5 , San Deigo

Colleagues ,

The minutes and presentations from the joint meeting of Geospatial and Big Data 
IGs at RDA5 , San Deigo earlier this month are now available at

https://rd-alliance.org/group/geospatial-ig/post/minutes-joint-meeting-ig-geospatial-ig-big-data-p5.html

Thanks to Chris Pettit  (University of Melbourne) for chairing this joint 
meeting  aimed at bridging synergies with Geospatial and Big Data research 
communities in particular for our Road Map Challenge ideas for Urban Science 
and City Analytics (joint ideas in Geospatial and Big Data ) See ideas in place 
at http://wiki.osgeo.org/wiki/GeoForAll_UrbanScience_CityAnalytics  and join 
the mailing list at  
http://lists.osgeo.org/cgi-bin/mailman/listinfo/geoforall-urbanscience

All those interested are welcome to join the thematic working group. We request 
that all participants  support the 'Open Cities Guiding Principles.'

Open Cities - Guiding Principles :

* All material created is made available for all under an Open License
* All material is carefully designed (modular componentry) so that it can be 
built upon by others
* All participants aim to reuse, extend and invent material (in that order)

Thanks also  to Christoph Stich for kindly putting together the minutes of the 
meeting . We also thank RDA Europe's Early Career European Researchers  
Scientists working with Data Support Programme for the RDA 5th Plenary which 
supported Christoph Stich
https://rd-alliance.org/early-career-european-researchers-scientists-working-data-support-programme-rda-5th-plenary.html

It was a great session with about 50 people involved ( at the event and online)

The link to a recording of the GoTomeeting in case anyone missed it and would 
like to watch is available at

We thank all presenters and participants for thier contributions and looking 
forward to expand these ideas in the future. See you at P6 at Paris (23rd-25th 
Sep, 2015) with a focus on Research Data for Climate Change.

[OSGeo-Discuss] EXI with XML data streams

2015-03-30 Thread Newcomb, Doug
Hi Folks,
Sitting in on a standards meeting and just heard about EXI, Efficeint XML
Interchange
http://www.w3.org/XML/EXI/.  It seems that this would be useful for
reducing bandwidth requirements for XML data streams such as WFS.  Has
anyone looked at that?

Doug,

I don't know about EXI, but most web servers should already support GZip 
compression out of the box, with no impact on WFS clientserver code, so IMHO, 
EXI should offer significant compression ratio over GZip-compressed XML to 
really be an incentive to be adopted by both WFS client  servers. WFS servers 
also often the possibility of alternate outputFormat to GML, such as zipped 
shapefile, etc..
