Although not technically space systems, computer software programs called Geographic Information Systems, or GIS, are at the heart of disaster management data integration, analysis, and sharing. GIS is where all the information from satellites, GPS, weather RADAR, field damage assessments, paper maps, and other sources are integrated and displayed for analysis and action. Many international, national, state, and local disaster organizations and others are now using GIS systems and are also routinely distributing their data in GIS formats so that it can be directly incorporated into GIS systems.
