CyberGIS Gateway is the leading online cyberGIS environment for a large number of users to perform computing- and data-intensive, and collaborative geospatial problem-solving enabled by advanced cyberinfrastructure. Supported in part by the National Science Foundation (NSF) CyberGIS Project, the Gateway provides a suite of scalable spatial analysis and modeling applications built on GISolve middleware infrastructure. The computation of analytical and modeling tasks is conducted within a cloud computing environment and several leading cyberinfrastructure environments such as the NSF XSEDE supercomputers and the Open Science Grid resources.
