GSKY

A distributed geospatial data server, which allows you to interact with datasets using standard community protocols. GSKY (pronounced ji-skee) accesses and analyses the geospatial data on NCI’s cloud and high-performance computing systems, and delivers it to a user device or website. Behind the scenes, GSKY manipulates the datasets so they seamlessly work together.

To use GSKY, choose from the list of datasets, specify a region and timeframe, and GSKY will analyse the information as harmonised data.
