Landsat 7 Satellite Capabilities
Historical Multispectral Earth Observation from the Landsat Archive
About the Landsat 7 Earth Observation Satellite
Landsat 7 is a U.S. Earth observation satellite launched in 1999 as part of NASA's Landsat program. It provides an invaluable historical record of environmental, agricultural, and urban landscapes, supporting retrospective studies and long-term change analysis.
The satellite is equipped with the Enhanced Thematic Mapper Plus (ETM+), capturing imagery in visible, near-infrared, and thermal infrared wavelengths. It includes a 15m panchromatic band, 30m multispectral bands, and a 60m thermal band, enabling broad applications in remote sensing and geospatial analysis.
While Landsat 7 no longer acquires new imagery, its archive remains a trusted source for environmental baselining, land cover classification, and long-term change detection.
Cost-Effective Access
Affordable archive imagery for long-term analysis and mapping workflows.
Wide Regional Coverage
185 km swath width enables efficient coverage of large areas per pass.
Trusted Historic Archive
Decades of consistent data for climate, land use, and environmental research.
Key Features and Benefits of Landsat 7 Archived Imagery
- ETM+ delivers multispectral and thermal infrared data, ideal for environmental and land surface monitoring.
- Supports long-term analysis of vegetation health, deforestation, urban expansion, and climate-related change.
- Archive imagery at 15m (panchromatic) and 30m (multispectral) resolution for GIS, mapping, and remote sensing.
- Complements modern missions by providing historic baseline data for AI training, trend modeling, and validation.
