Landsat 7, launched April 15, 1999, introduced the Enhanced Thematic Mapper Plus, and a new panchromatic band to continue the legacy of Earth Observation. The satellite acquired science data until January 19, 2024.

Landsat 7 is the seventh satellite of the Landsat program. Launched on 15 April 1999, Landsat 7's primary goal is to refresh the global archive of satellite photos, providing up-to-date and cloud-free images.

Landsat 7’s sensor has been called “the most stable, best characterized Earth observation instrument ever placed in orbit.” Landsat 7’s rigorous calibration standards have made it the validation choice for many coarse-resolution sensors.

2024年9月19日 · For 25 years, the Landsat 7 satellite acquired millions of images of Earth that supported studies of how land is used and how it has changed across urban, agriculture, forest, snow and ice-covered areas around the globe, as well as natural and manmade disasters.

2021年12月15日 · The valuable land surveys with Landsat 7 can be used in agriculture and forestry. The satellite’s panchromatic and infrared bands enable quality observations.

1999年4月15日 · Landsat 7 joined Landsat 5 in April 1999. Both Landsat 5 and Landsat 7 provide data for remote sensing and Geographic Information System (GIS) science and applications around the world. NASA was responsible for the development and launch of Landsat 7 and the development of the ground system.

Landsat 7 launched from Vandenberg Air Force Base in California on April 15, 1999, on a Delta II rocket. The satellite carries the Enhanced Thematic Mapper Plus (ETM+) sensor. The ETM+ provided useful scientific information about the world’s landmasses for 23 years.

1999年4月15日 · Landsat 7 was launched in 1999 and remains operational. The Explorer mode of the HEritage DAta VIsualisation tool (HEDAVI) allows users to process on-the-fly, visualise, share and export Earth observation data from ESA’s Heritage and Third Party Missions.

2024年6月7日 · Landsat 7 continued the long-term Earth observation Landsat program begun in 1972. Landsat 7 was a joint project between NASA, NOAA, and the US Geological Survey to obtain continuous high-resolution imagery of the Earth's surface.
