Which method is used to detect spatial distribution using satellites?
Field biology often requires landscape-level distribution patterns beyond ground plots. Remote sensing employs satellites like Landsat, Sentinel, and MODIS, aircraft, and drones carrying optical, infrared, and radar sensors to record reflectance repeatedly over large areas. Spectral signatures distinguish vegetation types, water, and animal habitats, allowing mapping of migration corridors and seasonal changes. Transects and quadrat sampling provide ground truth but cover limited area. Scintillation relates to radiation counting, not spatial biology. Hence satellite-based remote sensing provid
