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.
