Using DataFed to Build Fire-related Web Applications

DataFed (http://datafed.net) is a web infrastructure for accessing distributed air quality data and for processing and visualizing these data through web services. The modular and self describing web services available through DataFed are particularly well suited for conducting spatial and temporal data analysis of point datasets, such as satellite derived fire detection and surface fire observation data. Fire related data are available through numerous government web sites in the form of downloadable text files, images and Web Geographic Information Systems (GIS). While effective in accessing and visualizing fire data, these systems do not allow integration of data from other sources. DataFed is designed to combine data from multiple sources and to develop services for analyzing these data. This paper presents a case study for the type of “value-added” decision-support applications that can be developed using the DataFed infrastructure. The example applications provide tools for dynamically aggregating and comparing differences in fire location data through maps and time series.
