Full Name Landsat 7
aka L7, Landsat-7
Status Operational (extended)
Mission Agencies USGS, NASA Launch Date 15 Apr 1999
Mission Links mission site | mission site | data access portal | data access portal EOL Date Sep 2025
EO Portal Info NORAD Catalog # 25682 (TLE)
International Designator 1999-020A
Orbit Type Sun-synchronous Orbit Period 98.9 minutes
Orbit Sense Descending Orbit Inclination 98.2 deg
Orbit Altitude 697 km Orbit Longitude
Orbit LST 08:00 Repeat Cycle 16 days
Objectives and Applications Earth resources, land surface, environmental monitoring, agriculture and forestry, disaster monitoring and assessment, ice and snow cover. 5-year nominal mission life, currently in extended operations with the LST allowed to drift. Routine science mission data operations ended following the declaration of successful Landsat 9 operations. Landsat 7’s orbit has been lowered to accommodate a potential OSAM-1 servicing mission in the 2026 timeframe.

GA Landsat Collection 3

The United States Geological Survey's (USGS) Landsat satellite program has been capturing images of the Australian continent for more than thirty years. DEA takes the hundreds of thousands of images, prepares them for Australian conditions, and makes adjustments to correct inconsistencies caused by changes in the atmosphere each time an image is captured (i.e. absence or presence of cloud cover), so that the data can be analysed to provide information about our changing continent. This corrected data set is known as Landsat Surface Reflectance, and it forms the basis for many of the other information products produced by DEA. Products derived from the surface reflectance collection include Fractional Cover, Water Observations from Space, the Intertidal Extents Model, and High and Low Tide Composites. Read more

Landsat Collection 1
Landsat Collection 1 consists of Level-1 data products generated from Landsat 8 Operational Land Imager (OLI)/Thermal Infrared Sensor (TIRS), Landsat 7 Enhanced Thematic Mapper Plus (ETM+), Landsat 4-5 Thematic Mapper (TM)*, and Landsat 1-5 Multispectral Scanner (MSS) instruments. Read more

Landsat 5 ETM+ GTC Systematic Processing

The Landsat Enhanced Thematic Mapper Plus (ETM+) instrument was introduced with Landsat-7. ETM+ data cover the visible, near-infrared, shortwave, and thermal infrared spectral bands of the electromagnetic spectrum. Access is provided through the ESA TPM scheme. Read more
