Case Studies

National Data Grid

The National Data Grid project aims to demonstrate an innovative infrastructure for managing grid cell (raster) data, and to promote the use of such data in a consistent way across Australia.

Geospatial data, e.g. data that may be displayed on a map, is produced and used by many organisations across Australia. The uses for this data range from infrastructure planning to agriculture and beyond.

CRC-SI required a system for the storage and transmission of geospatial raster data. VPAC developed two components of this system:

  • 1) the National Nested Grid (NNG), being a system for indexing Australian raster datasets;

  • 2) the Raster Storage Archive (RSA), which is a web-based system for storing raster data.
These components enable greater collaboration between the users of geospatial raster data. CRC-SI can now use these components to encourage the adoption of national raster data standards.
