Enhanced Thematic Mapper Plus (ETM+)

The Enhanced Thematic Mapper Plus (ETM+) is a remote sensing instrument onboard Landsat 7, a satellite that captures detailed images of Earth's surface. It functions like a sophisticated camera, collecting data in various wavelengths of light, including visible and infrared, to monitor land use, vegetation, water, and urban development. ETM+ provides high-resolution images that help scientists, planners, and environmentalists analyze changes over time, aiding in resource management, environmental monitoring, and disaster response. Its advanced sensors enable precise, multispectral imaging, contributing to a better understanding of Earth's dynamic processes.
