ACRES Landsat Multispectral Scanner (MSS)

The Landsat series of satellites commenced acquiring remotely sensed data with the launch of Landsat 1 in 1972. The Landsat satellites travel at an altitude of 705 kilometres and provide coverage of the entire globe every 16 days. The Multispectral Scanner (MSS) sensor has been the primary Earth-observing instrument. MSS images in four spectral bands (called Bands 4-7 on LS1,2&3 and 1-4 on LS 4&5) covering the visible and near infrared regions of the electromagnetic spectrum. The MSS ground swath is 185 kilometres wide, with a nominal 80 metre pixel resolution. The archive of ACRES MSS data dates from 1979 onwards. ACRES MSS archive contains data from the following Landsat satellites: Landsat 2 commenced November 1979, ceased Feb 1982 Landsat 3 commenced November 1979 ceased August 1982 Landsat 4 commenced August 1982, ceased May 1984 Landsat 5 commenced 9 April 1984, ceased November 1997 - Band 4 (original band 7) data poor quality from 29 April 1994 - Band 4 (original band 7)switched off permanently 20 August 1995 Note that MSS data from Landsat 3 & 4 is of poor quality and requirements for this data need to be discussed with ACRES prior to purchase.

ACRES Landsat 7 Enhanced Thematic Mapper Plus (ETM+)

The Landsat series of satellites commenced acquiring remotely sensed data with the launch of Landsat 1 in 1972. Landsat satellites travel at an altitude of 705 kilometres and provide coverage of the entire globe every 16 days. Landsat 7, launched on 15 April 1999, carries the Enhanced Thematic Mapper Plus (ETM+). As the name suggests, the ETM+ sensor is similar to the TM sensor but has some added features. It provides imagery in the same seven spectral bands as the TM sensor with 30 metre resolution, but has an added panchromatic band with 15 metre pixel resolution. ETM+ also has an enhanced thermal band with a 60 metre resolution. Its ground swath is 185 kilometres. A full scene is approximately 184 kilometres by 172 kilometres. The archive of ACRES products includes ETM+ data from 6 July 1999 onwards.

PSMA Data 2016

PSMA Australia combines spatial data from Australia's governments to create national spatial information datasets that include features such as roads, street addresses, and cadastral and administrative boundaries. Geoscience Australia has entered into an agreement with PSMA Distribution Pty Ltd in June 2013 which provides GA access to key PSMA data products. The conditions of use are stipulated in the End User Agreement (EUA) and simplified form of Terms and Conditions (see below) will be made available soon to GA staff. The EUA has been extended in December 2013 to include the Land Tenure and Postcode Boundaries datasets, effectively providing GA access to the whole suite of PSMA products. These are: -Administrative Boundaries -Features of Interest -CadLite -Geocoded National Address File (G-NAF) -Land Tenure -Postcode Boundaries -Transport & Topography For more details about these products - including content and maintenance cycle - please refer to PSMA website (http://www.psma.com.au/list-products/).
