摘要: We describe the design, implementation and performance of a novel airborne system, which integrates commercial waveform LiDAR, CCD (Charge-Coupled Device) camera hyperspectral sensors into common platform system. CAF’s (The Chinese Academy Forestry) LiCHy (LiDAR, Hyperspectral) Airborne Observation System is unique system that permits simultaneous measurements vegetation vertical structure, horizontal pattern, foliar spectra from different view angles at very high spatial resolution (~1 m) on wide range platforms. The geo-location accuracy LiDAR about 0.5 m, with 0.15 m 0.3 respectively. image within 2 pixels for nadir observations 5–7 large off-nadir 55° multi-angle modular when comparing to product. complementary nature LiCHy’s makes it an effective comprehensive forest inventory, change detection, biodiversity monitoring, carbon accounting ecosystem service evaluation. has acquired more than 8000 km2 data over typical forests across China. These are being used investigate potential optical remote sensing applications in management, accounting, evaluation, aid development similar satellite configurations. This paper describes integration instrument processing workflow. also demonstrate characteristics, current coverage, applications.
