TRANSCRIPT
Joint EuroSDR/AGILE project on Crowd Sourced Mapping
Peter Mooney and Jeremy Morley
Progress Pathway
September/October 2011
Begin discussions on how Crowdsourcing could be used as some form of Update Intelligence/complementary data stream(s) in National Mapping Agencies
January 2012 - Nottingham UK
Workshop at University of Nottingham - representatives from Industry, Academia, AGILE, Euro-SDR, National Mapping Agencies (10)
Summer 2012Call for applicationsReview of applicationsAward Process
4 projects commenced in late 2012 with 1 project commencing in March 2013
Autumn 2013Projects completedPresentations made to AGILE and EuroSDR annual meetingsA very positive set of outcomes!

Some interesting results (soon to be published in a paper)● 180,000 images considered from Flickr, 13,000 contributors, 22,000 unique
tags
● Tag is not an official toponym but still indicates a specific location: e.g. ‘louvre’
● Approximately 35% of the toponyms listed in IGN gazetteer could also be found in the extracted tags
● The tags of Flickr images are a valuable source to gather placenames from user-generated content (UGC).
● There is potential to enrich the official gazetteers with more content from UGC.

Outcomes:○ Stuttgart and Calw (Baden Wurttemberg)○ Road network in both datasets very similar in rural
areas○ More detail in OSM in urban centers
○ Both software tools (ifp, 1Integrate) could perform the conflation - but there are disadvantages (manual input vrs small areas automatic)

Geographical names (vernacular names/ toponyms) have been identified as potential targets as they are difficult to collect on a large scale and easy to collect locally, thus ideal for crowd sourcing - using Gamification Techniques.

Crowdsourced data is collected for presentation to an authorized IGN officer who considers inclusion in the IGN Toponyms database.
Presented as a paper at the AGILE 2013 conference - other papers listed in the final report
Dr. Giedrė Beconytė (LT) "Collection and visualisation of alternative tourism sites and objects in Lithuania." Sponsor: AGILE (50%); EuroSDR (50%) NMA: National Land Service under the Ministry of Agriculture of the Republic of Lithuania (spatial data and ortho imagery)
“Crowdsource the collection of information on diverse objects and sites that are typically not included in official information sources and do not belong to the tourist infrastructure network”.
Paneriai Railway Tunnel
Development of a Wiki-type system to allow users to provide information on sites of cultural or natural importances.
A user-interface is provided which helps guide users to provide a classification of the objects.
Administrators are active to control data input and moderate.

Periodically updates will be pushed to the National Geoportal www.geoportal.lt
Jimena Ramos (ES) and Dr. Rodolphe Devillers (CA)"Ontology-based OSM and OS integration"Sponsor: AGILE NMA: Using openly available NMA data
Semantic Heterogeneity in OpenStreetMap datasets
Example: tag (bus_stop) and (stop_position) - both refer to the same real world phenomenon. Also (highway=platform) and (public_transport = platform)
This can happen with flexible data models such as those used in VGI as users have great freedom in choosing these ‘tags’
AIM: If semantic heterogeneity could be removed from OSM datasets then they would be in a much better condition for integration and interoperability with official authoritative datasets

Presented at the AGILE 2013 conference AND workshop
Phase 1: Current Status
All projects have been completed!Some projects are part of other larger projects
Thanks to ESRI, AGILE, and EuroSDR for a really great combined effort!
Final report has been written - distributed to EuroSDR email list (October 2013)
Report will be made publicly openly available
Phase 1: Important Outcomes
Physical Indicators: Workshop, Final Report, Several published papers by the projects with acknowledgements to EuroSDR/AGILE.
Value-added Indicators of Success:● Very successful from NMCA point of view - generated
ideas and concepts which academia researched● Showed the potential of Crowdsourcing/VGI when
NMCA has control/input into the process● Lots of scope to develop these ideas further and build
on this momentum - now is the moment!
Phase 2: Second round of internships
Proposals being made to EuroSDR and AGILE
Funding structure will be similar
Workshop in 2014 (Jan, Feb)
Continued engagement between National Mapping Agencies and Academia is crucial
More details tomorrow!
Thanks for listening todayStayed tuned via mailing lists, Twitter, etc for
Phase 2 announcements
