Thematic Mapper (TM)

The Thematic Mapper (TM) is a sensor onboard the Landsat satellites used for Earth observation. It captures detailed images of the planet’s surface across multiple spectral bands, including visible and infrared light. These images help scientists analyze land use, vegetation health, water bodies, and soil conditions. Each spectral band provides different information, allowing for precise mapping and monitoring of environmental changes over time. Essentially, the TM acts like a sophisticated camera that reveals various features of the Earth's surface, supporting research in agriculture, forestry, urban planning, and environmental management.
