Background documents on crowdsourcing and collaborative mapping

Technical discussion group on GeoRSS technology
The GeoRSS technical discussion group was set up following the December 2013 IWG-SEM teleconference with the goal to create an operational solution of GeoRSS feeds to share metadata related to emergency mapping activities by the first quarter of 2014. The technical discussion group was formed by 18 people from DFO, DLR, EC-JRC, GWU, ITHACA, PDC, RIT, OOSA/UN-SPIDER, USGS/EROS, and it is chaired by Jan Kucera from EC-JRC.

Email discussion on choice of RSS
Email comment by RIT (14 December 2013):
It might be worth looking closer at the choice of RSS in general, as it seems its future is uncertain, see:
- For example, the USGS has stopped offering GeoRSS-based earthquake feeds like they did in the past (see: http://earthquake.usgs.gov/earthquakes/feed/v1.0/)
Email comment by ITHACA (16 December 2013):
The main rationale behind choosing GeoRSS was to identify a standard/OGC compliant solution allowing people to subscribe to a specific feed exploiting the non-geospatial component with common software (e.g. e-mail clients) or to use specialized GIS software to access also the geospatial component of the feed. Furthermore organizations involved in IWG-SEM should already have the technical capacity to broadcast GeoRSS feeds.
Email comment by UN-SPIDER (16 December 2013):
Jumping on RSS might be a bit late - sure it works still great for most applications, though e.g. twitter switched off rss already in favor of json support. (Seeing twitter as one of the top micro blogging services and a repository of near & realtime data (particularly in dm), you should keep an eye on what they're doing)
What does OGC foresee? C. possible developments in one of the technical committees (i.e. http://www.opengeospatial.org/standards/requests/89 & http://www.opengeospatial.org/projects/groups/gservrestswg)
GeoRSS related links
The following links were shared by Franck Albinet in a presentaiton on Geo-visualization during the 2014 UN-SPIDER RSO meeting in Vienna; they might serve as food for thought for the further development of IWG-SEM metadata-sharing:
- collection of all links shared by Franck: http://urlmin.com/15lf
- ckan - the open source data portal software
- tweetping - real time data mapping
- Sahel response (mapbox, example for giving some of the GIS capabilities into the hand of non-experts)
- viz-carbontool (example for dynamic maps as opposed to static SDI to get questions answered on what, where and why)
- CartoDB (easily develop applications to visualize datasets in a dynamic way)
- D3.js ("swiss knife of data visualization")
Examples of feeds and webmapping tools that different providers are currently using (compiled on 19 May 2014 by UN-SPIDER):
- DLR/ZKI: geoRSS and kml feeds
- International Charter geographic tool --> possibility to export as csv and kml
- Copernicus: GeoRSS
- NASA: near real time MODIS flood mapping: atom feeds
- USGS/Fewsnet --> near real time data available for download directly from the web, no feed available, e.g. NDVI anomalies for drought monitoring
- NASA TRMM --> data available for download via ftp, no feed
- USGS NRT earthquakes: atom, csv, GeoJSON, kml, QuakeML
- NASA NRT active fire data: shp, kml, wms, txt
