Evolving GIS Technologies Advance Disaster Management

“A picture is worth a thousand words” is a saying largely undisputed in its accuracy. There’s a reason several different languages and cultures have a version of this popular idiom. Graphics can convey in seconds what words need more time to say. When disasters strike, every minute and second becomes incredibly precious. During critical times, geographic information systems (GIS) become indispensable in disseminating data in a way everyday people can quickly understand.

A Geographic Information System (GIS) is a system that can map and examine changes on Earth by analyzing and displaying spatially related data from various data sources. Geospatial data from various sources, such as satellite imagery, GPS data, and descriptive information associated with a specific location, can be integrated and collectively analyzed using GIS.
