An International Conference of Crisis Mappers (ICCM) 2011 happened in Geneva. This conference is an interesting confluence of GIS, social media, crowd-sourcing, mobile and web-based application and participatory mapping all used for early warning for rapid response to complex humanitarian emergencies.
Some of the highlighted talks during the International Conference of Crisis Mappers (ICCM) 2011:
Adam Finck of the NGO 'Invisible Children' and their implementation of the Lord's Resistance Army's(LRA) Crisis tracker. The talk concentrated on an early warning system for those on the frontline, warning of ongoing attacks, tracking the movements of the LRA and exposing the atrocities committed.The tool's role is to spread the news of one of Africa's longest wars.
Lars Bromley from UNOSAT and 'PhotoGeotagger'.A very interesting talk that dealt with a low-cost method of linking photos of large areas of(relatively) low resolution data via crowdsourced methods.
