地面植被的主被动同步观测实验方法

Experimental Method for Acquiring Active-Passive Synchronous Data from Vegetation on the Ground

针对植被冠层结构参数主被动遥感协同反演的问题,开展了不同地形、不同植被覆盖类型的地面观测实验,获取了典型植被不同方位、不同角度的地面激光雷达和成像光谱数据,同时,测量了多种冠层结构参数,构成了与飞行数据配套的地面同步观测数据集。该文介绍了实验中样地选择,观测站点设置,主被动数据获取,辅助数据测量等过程的具体目标和设计;总结了实验中获得的主要经验,对遥感类专业的实践教学及科研实验均具有指导意义。

For researching active-passive synergic retrievals of vegetation canopy structure parameters,a ground- based observation has been carried out on different topography and different vegetation types,in which the light detection and ranging（LiDAR） and hyperspectral data of typical vegetation are collected from different locations and angles.Meanwhile,a variety of canopy structure parameters are measured.The overall results of this experiment form a synchronous observation data set on the ground,corresponding to the flight data.The specific objectives and experimental design are introduced,including sampling plot selection,observation station setting,active- passive data acquisition,and auxiliary data measurement.The main experimental experience is also summarized,which is of important guiding significance for professional research and educational practices in the field of remote sensing.
