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. Landsat 5, launched in 1984, carries the Thematic Mapper (TM) sensor in addition to the Multispectral Scanner (MSS). The Thematic Mapper is a higher resolution sensor. It provides imagery in seven spectral bands (called Bands 1-7), covering the visible and near, middle and thermal infrared parts of the electromagnetic spectrum. TM has a 30-metre pixel resolution for all bands except Band 6 which has a 120-metre resolution. Its ground swath is 185 kilometres. A full scene is 185 kilometres by 172 kilometres. The archive of ACRES products includes TM data from September 1987 to December 1999 and July 2003 onwards.
