High Performance, Federated and Service-Oriented Geographic Information Systems

چکیده
General purpose of GIS is extracting information/knowledge from the raw geo-data. The rawdata is collected from sensors, satellites or any other ways and stored in databases or file systems. The data goes through the filtering and rendering services and, presented to the endusers in human recognizable formats such as images, graphs, charts etc. A well-known example of GIS is map viewers which process layers of geospatial data to create map images. GIS are used in a wide variety of tasks such as urban planning, resource management, emergency response planning in case of disasters, crisis management and rapid response etc.
