**Landsat band properties — what each band is good for** (TM/ETM+ numbering). - **1 (Blue, 0.45–0.52 µm)** — coastal water mapping, soil/vegetation discrimination, forest type mapping, cultural features. - **2 (Green, 0.52–0.60 µm)** — vegetation ID and vigor (green reflectance peak), cultural features. - **3 (Red, 0.63–0.69 µm)** — chlorophyll absorption; plant species, soil/geologic boundaries, cultural features. - **4 (NIR, 0.76–0.90 µm)** — vegetation biomass, crop ID, soil/crop and land/water contrast. - **5 (SWIR, 1.55–1.75 µm)** — water in plants; crop drought, plant health; clouds vs. snow vs. ice. - **6 (Thermal, 10.4–12.5 µm)** — vegetation/crop stress, thermal mapping, thermal pollution, geothermal. - **7 (Mid-IR, 2.08–2.35 µm)** — rock/soil discrimination, soil and vegetation moisture.
