CyberGIS Jupyter

CyberGIS-Jupyter is an innovative cyberGIS framework for achieving data-intensive, reproducible, and scalable geospatial analytics. It is based off of the Jupyter Notebook, which has built-in cyberGIS capabilities to accelerate gateway application development and sharing.

The CyberGIS Gateway

The leading online cyberGIS environment powered by advanced cyberinfrastructure.

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 ROGER supercomputer.

Gateway Status

Gateway Version: CyberGIS Gateway v2.5b
Current build: r615
