Crisis Mapping
summary
Satellite and smartphone data get framed as fun location apps but the claim here is operational: governments report ~80% of data is location-based and 74% of citizen services are geospatial, so open mapping changes disaster response. Weekend crisis camps and Crisis Commons mobilize thousands to build SMS/iPhone tools; search-and-rescue teams use OpenStreetMap on GPS units in Haiti to find trapped people. Global access stats: 24% have internet, 80% cell coverage, ~50% own mobiles, so SMS-first interfaces matter.
