Data for the collaborative project with the South Australian Department of Environment, Water and Natural Resources (DEWNR)

This ALOS processed data covers the area from Newcastle down to Batemen's Bay on the east coast of New South Wales for Geoscience Australia. The data has been delivered in a number of both tile and mosaic files. The data delivered to Geoscience Australia consists of 8 AVNIR scenes and 13 triplet PRISM scenes.

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. Tiles areas are available at: <a href="http://www.ga.gov.au/acres/prod_ser/agotilemap.jsp">http://www.ga.gov.au/acres/prod_ser/agotilemap.jsp</a>

This collection is used to provide an environment for external access to the Australian Geoscience Data Cube Virtual Desktop Interface (VDI).

ADMAP is a Gridmerged compilation of over 700 individual survey TMI grids, with a cell size of approximately 80 m (in fact it is 0.00833333 degrees). The first preliminary grid at this resolution with data type IEEE4ByteReal has been further processed to produce an enhanced colour image (a 3-band Unsigned8BitInteger byte file) of the TMI grid, using the rain_gomp rainbow look-up table and a north-east gradient.

The SPOT PAN data set is acquired by earth orbiting remote sensing satellites. These satellites carry two types of sensor systems known as "active" and "passive". A "passive" system generally consists of an array of small sensors or detectors which record (as digital numbers) the amount of electro-magnetic radiation reflected and/or emitted from the Earth's surface. The SPOT PAN is a passive system. The digital data acquired by the satellites are transmitted to ground stations and can be used to reconstitute an image of the Earth's surface not too dissimilar to an aerial photograph. Data are received through the ACRES antenna at the Data Acquisition Facility at Alice Springs enabling coverage of the Australian landmass. The recorded data are air-freighted daily to the Data Processing Facility in Canberra where it is catalogued and archived. SPOT-LITE was created as a result of Geoscience Australia's national mapping program. Geoscience Australia uses SPOT PAN imagery to revise its 1:250 000 scale maps. Usually two to four strips of imagery are used for each 1:250 000 map area that covers 1 degree of latitude and 1.5 degree of longitude. The imagery is acquired at near-vertical viewing angles wherever possible to minimise distortions. Each strip of imagery is geocoded, that is rectified to match ground control points which are digitised from the largest scale mapping available in the area (generally 1:25 000, 1:50 000 or 1:100 000 scales). Most SPOT-LITE tiles are also orthocorrected, that is, they have relief displacements removed through the application of Geoscience Australia GEODATA 9 second Digital Elevation Model. The three strips of imagery are then merged together to form a mosaic across the 1:250 000 map area. There may be some minor difference in visual appearance on either side of the join lines because the images were acquired on different dates with different lighting conditions and vegetation characteristics. The mosaic is divided into 24 tiles, each corresponding to a 1:50 000 map sheet area on the GDA 94 datum. Adjacent 1:250 000 areas were not mosaicked together. Because of this there may be minor differences in visual appearance between tiles on either side of a 1:250 000 sheet boundary and some minor positional mismatches. 1:250 000 sheet boundaries are clearly indicated on the SPOT-LITE catalogue with a red line.
