Former classified satellites are now increasingly used to deal with disasters. FEMA is using both classified and non-classified satellite imagery to monitor disasters. Further, FEMA meshes GIS with satellite imagery for various applications. Bob Chen talked about the need for integrating an assortment of technologies such as remote sensing platforms and data management systems. He suggested using integrated data warehousing approaches to combine spatial and temporal data.
