A multi-tiered representativeness framework mitigating spatial scale effects in FVC validation: UAV-based assessment of global products in Qinghai-Tibetan Plateau alpine grasslands
Ground-measured fractional vegetation cover (FVC) data are critical for validating satellite-derived FVC products. However, spatial scale mismatches between ground plots and satellite pixels, compounded by the scarcity of field data in remote regions, introduce significant uncertainties in product v...
