Landsat 7

About

Landsat 7 is a United States satellite launched in 1999 as part of the Landsat program, which has been providing Earth observation data since 1972. It is a valuable tool for a range of applications, including agriculture, forestry, and environmental monitoring. Landsat 7 is equipped with an advanced multispectral imaging instrument, providing data in the visible, near-infrared, and thermal infrared regions.

Landsat 7’s ETM+ sensor replicates the capabilities of the highly successful Thematic Mapper instruments on Landsat 4 and 5 but also includes new features that make it a more versatile and efficient instrument for global change studies, land cover monitoring/ assessment and large area mapping. The primary features are a panchromatic band with 15m spatial resolution; onboard, full aperture, 5% absolute radiometric calibration; and a thermal infrared channel with 60m spatial resolution.

Cost effective

A great option for low-cost satellite imagery and geospatial data.

Wide swath width

Swath width of 185 km, allowing for large-area coverage in a single pass.

Features and Benefits

• Landsat 7 provides multispectral imaging data, allowing for detailed monitoring of land use and land cover changes over time. This makes it a valuable tool for a range of applications, including land management, agriculture, and forestry.
• Landsat 7 is equipped with a thermal imaging instrument, providing valuable information for monitoring vegetation health, water quality, and urban heat islands.
• Landsat 7 is part of the Landsat program, which has been providing Earth observation data since 1972. This long record of data provides a valuable resource for researchers and organisations monitoring long-term changes on the Earth's surface.
• Landsat 7 is a valuable tool for monitoring environmental changes, including deforestation, wildfire, and natural disasters.
