AGRI: The Australian Geographic Reference Image

Brief description

Geoscience Australia is distributing the Australian Geographic Reference Image (AGRI), a national mosaic which provides a spatially correct reference image at a 2.5 metre resolution across Australia. Geoscience Australia developed AGRI to address the need for a higher resolution reference image, of known accuracy, over the entire Australian continent.

Geoscience Australia developed AGRI between July 2009 and June 2011. The project was made possible by a combination of new data from Japan's Advanced Land Observing Satellite (ALOS) which produced panchromatic observations at 2.5 metre resolution; new `full pass' processing techniques for rectification of satellite imagery developed in the Cooperative Research Centre for Spatial Information and included in the Barista software; Geoscience Australia's expertise in Geodesy and Global Positioning System, and the capabilities of the Australian Spatial industry in GIS database design, field survey and image processing.
