Framework of the opportunities of the GeoWeb

	Map mashup	Contributory platform	Collaborative platform
Objectives
General	Inform people	To collect relevant data to support decision-making	To produce and update base maps and data
Response phase	Information on the progress of the disaster, security measures (confinement, locations of emergency evacuation)	To receive the calls for help and information on affected areas and populations (number and condition of the victims, disappearances, damage extent, access for emergency services…)	Updating base maps and data for relief agencies and NGOs for emergency response
Recovery phase	Information on the situation (missing persons, damage, contaminations), sanitary conditions (health centres, water supply), facilities and management structures (administration, associations, insurances …)	To receive requests for supply, security, health, lifeline…	Updating base maps and data for authorities and NGOs to facilitate reconstruction and development planning
Technologies and features	Map mashups, Web services (API) Visualization (base maps, layers) and aggregation tools	Contribution platforms (Ushahidi), Web services (API) Crowdsource platform, filtering tools,	Collaborative platforms (OSM, Google Map Maker, wiki, geoCMS…)
Data	Authoritative and non-authoritative data (points, lines, zones)	Non-authoritative data (points)	Authoritative and non-authoritative data (points, lines, zones and base maps)
Constraints	Information flow, Visualization, Understanding the message Reliability	Temporal emergency, Data accessibility, Fragmented data aggregation Trust, reliability	Data quality, Interoperability, Licensed data, Liability
Strengths	Interoperability of systems, Cross-checking of data sources, Flexibility of platforms, Variety of contents (multimedia) Simplicity and ergonomy of interfaces	Real time data (deployment timelines), Triangulation of sources (cross checking), Communication supports	Crowdsourcing, Mass effect, emulation, Cost saving, Collective intelligence,
Weaknesses	Non-homogeneous sources, Map interface, Poor and non-homogeneous legends and graphic semiology,	Reliability of contributory data, Complexity of the validation and qualification mechanisms	Reliability of contributory data, Complexity of the validation and qualification mechanisms
Opportunities	Providing faster information to the victims, More communication media (mobile applications)	Building a culture of participation and contribution, People’s science (citizen sensors), Local knowledge acquisition, Maintenance of the social bond (mobile application)	Improving citizens’ spatial skills and spatial reasoning Developing alternative ways to update geospatial databases
