Features

The Grid Spatial Data Federation not only allows for mass data storage, but also reduces redundant development costs through collaboration. Using a cloud-based storage model for image management, the Federation facilitates the sharing of valuable data and enhances spatial information computing and application services. To implement features like data storage, image Federation, and intelligent computing, the National Center for High-Performance Computing established the user-oriented Geospatial Data Exchange Platform (GDXP) in 2022, offering these features:

  • Reduce Development Expenses
