DESCRIPTION
A presentation given during the COST Session in HAICTA 2013 (Cofru, Greece) about the aims and work of two COST Actions: ENERGIC (IC1203) and Mapping and the citizen sensor (TD1202). The presentation was put together by Cristina Capineri, Giles Foody and Vyron Antoniou.

Overview
Web 2.0
Impact of Web 2.0 on GI
Impact of Web 2.0 on GI
The Crowd and the Sensors
Scientific Field
• Crowdsourced information (user generated spatial content)
• New and burgeoning
• Unexpected and unsolicited
• Open access and free of costs
• Mainly produced by non-experts (“smart mobs”)
• Unfiltered, non standardized
Participative approach: Common-based peer knowledge production; «collective intelligence»
“Prosumers”: People as producers and users of information
Multidisciplinary & Related fields: Crowdsourcing, Citizen Science, User Generated Spatial Content, collective intelligence, Geoweb, Geocomputing, social sciences...
General Innovative Features
Research Challenges Big Data – size of datasets, efficient spatial and temporal algorithms
Information integration (multi-source, multi-disciplinary, multi-temporal, multi-media, multi-lingual)
Statistical problems of integration – development of suitable analysis techniques
Retrival and storage (API, content base, privacy restriction, ..) with spatial analysis capabilities
Trust, reputation and quality
Socio-technical aspects: motivations, incentives, behaviour
Technology Issues Elaborate tools and processes for top-down and bottom-up modeling
Tools and processes for analysis
Integrate web 2.0 and ICT developments
Elaborate simple formats to capture contents, flexible API’s to access and manipulate it
Technologies for public participation and to enable people to become sensors (fixed and mobile networks)
“Accurate and timely maps are a production in a changing world is a major scientific and practical
grand challenge”

Provide ground information to integrate remote sensed information and records
Why VGI? (What can be done)
...“Critics dubbed the laser ‘a solution looking for a problem.’ In fact, it took years for many potential uses of the laser to be recognized, and new laser applications are still being discovered today”…
Why Laser?
