Presented at the GeoWeb 2010
Conference.

Presenters: Andy Gup, Technology Lead & Allan LaFramboise, Technology Lead - ESRI
Description: Real-time social media systems, such as Twitter, has proven to be exceptionally valuable to help monitor and manage a number of disaster situations such as the Haiti earthquake. Since users can Geotag their tweets, GIS applications can be used to take advantage of the geolocation metadata to perform more advanced mapping and spatial analysis on the information. This session illustrates how developers can capture this real-time data and leverage it using the capabilities of GIS.
