The product SAR.GEC is a digital image generated from raw SAR data takes using up-to-date auxiliary parameters, with the best available instrubmental corrections applied, precisely located and recified onto a map projection. The ESA SAR.GEC format is based on teh general definistion of the SAR CEOS format (ref. ER-IS-EPO-GS-5902).

Significant advances in regional exploration and surface materials mapping are possible using spectral data and specialized remote sensing methods. Benefits for mineral explorers, land-users, government and university researchers are now available using improved ASTER calibration techniques. HyMap and ASTER calibration, processing and standardisation approaches have been produced as part of a large multi agency project to facilitate uptake of these techniques and make them easily integrated with other datasets in a GIS. Collaborative research comprising Geoscience Australia, the Commonwealth Scientific Research Organisation (CSIRO) and state and industry partners, on the world-class Mt Isa mineral province in Queensland was completed in 2008 as a test-case for some new methods. The project demonstrated that geochemical information about mineral deposit 'footprints' and alteration chemistry can be acquired by analysing spectral ground response, particularly in the short-wave infra-red. Key materials that can be identified include clays and magnesium/ iron/ aluminium oxyhydroxides, as well as information on mineral composition, abundance and physicochemistries (including crystallinity) for minerals such as kaolinite, which can be used as a surrogate for identifying transported versus in situ regolith material. The identification and classification of regolith materials and thickness indicators is essential to facilitate on-going exploration in many challenging regions such as South Australia.

The product SAR.GEC is a digital image generated from raw SAR data takes using up-to-date auxiliary parameters, with the best available instrumental corrections applied, precisely located and rectified onto a map projection. The JERS SAR.GEC format is based on the general definition of the SAR CEOS format (ref. ER-IS-EPS-GS-5902).

This document is the Data Format Control Book (DFCB) for the Landsat 7 (L7) Enhanced Thematic Mapper Plus (EMT+) Level Zero-R Distribution Product (LORp). It focuses on the Hierarchical Data Format (HDF) of the Landsat 7 L0R product available from the Centre for Earth Resources Observation and Science (EROS) Landsat Archive Manager (LAM).

The Disaster Monitoring Constellation (DMC) is a constellation of satellites (presently eight) owned by various countries; operating together to provide frequent observations of the Earth for monitoring natural disasters. The DMC satellites operate in the visible to near-infra-red part of the spectrum, which makes them very useful for crop and forest monitoring as well as general earth observation. DMC satellites have been used in emergency response in Australia, providing daily images of the progress of floods through Queensland and New South Wales during the February 2012 flood event. DMC imagery is also used to augment data acquired from the Landsat series of satellites. The DMC SLIM-6-22 sensor has a slightly higher spatial resolution of 22 metres and a higher revisit rate of four days; compared to Landsat 5 TM sensor with a spatial resolution of 30 metres and a revisit rate of 16 days. In addition the dual sensor layout on the satellites allows a 620 kilometre wide swath to be acquired in a single pass. DMC satellites have three spectral bands: green, red and near infra-red; where seven bands are available from Landsat 5 TM data. Comparisons of the current generation of DMC satellites with Landsat-7 ETM+ have demonstrated that the calibration accuracy is within 1 - 3%. To maintain the calibration the DMC satellites are routinely cross-calibrated with Landsat-7 ETM+. Landsat-5 was a key source of imagery throughout the world; until the acquisitions of imagery was suspended in 2011. To address the shortfall in access to medium resolution data, Geoscience Australia has acquired large regional coverage of DMC data from DMC Imaging International (DMCii). This acquisition will help to address monitoring needs until Landsat-8 imagery is available in mid-2013.

Geoscience Australia, ACRES distribute Landsat Multispectral Scanner (MSS), Thematic Mapper (TM) and Enhanced Thematic Mapper Plus (ETM+) data for a series of epochs or time frames covering Australia. The first epoch is 1972. These data have been produced and provided by the Australian Greenhouse Office (AGO). AGO use the data in their National Carbon Accounting System for monitoring land clearing and revegetation. This data is only available through ACRES and ACRES Landsat Distributors, and not through the AGO. More information is available at <a href="http://www.ga.gov.au/acres/prod_ser/agosuite.jsp">http://www.ga.gov.au/acres/prod_ser/agosuite.jsp</a> This data is available in 1:1M tiles or as a full continental Mosaic.
