The NCI-developed GSKY service (pronounced ji-skee) provides a high performance service for environmental and geophysical data based on data aggregation, data cubes and coordinate transformations. GSKY provides the ability for users to interact with entire datasets and the information they contain using standard community protocols. Many client software services can access data via GSKY since we follow well-known protocols used throughout the geospatial community.
Transparent to users, GSKY uses a distributed back-end data server and parallel IO design to enable a fast response to data. We have enabled GSKY on many of our large data collections, providing real-time access. This is particularly relevant for collections such as large time-series data from satellite earth observations which span decades and uses petabytes of data.
