典型地表类型多角度反射率数据集

在长春净月潭遥感实验站农业实验田人为改变不同地块的粗糙度和含水量，使用ASD光谱仪依次对各个地块进行多角度测量；在新疆维吾尔自治区阿勒泰地区使用PSR-3500波谱仪对积雪进行多角度反射率测量；在甘肃省张掖市使用SVC HR-1024全波段地物光谱仪对荒漠植被进行多角度测量。数据内容包括光谱反射率、测量时间、经纬度、测量高度、测量次数、测量人、预处理人、审核人、日光情况、云量、气温、太阳天顶角、方位角、观测角度等。该数据集共66条。

Multi-angle measurements were sequentially conducted on each plot using an ASD spectrometer at the agricultural experimental fields of Changchun Jingyuetan Remote Sensing Experimental Station, where the roughness and water content of different plots were manually adjusted; Multi-angle reflectance measurements of snow cover were carried out in Altay Prefecture, Xinjiang Uygur Autonomous Region using a PSR-3500 spectroradiometer; Multi-angle measurements of desert vegetation were performed in Zhangye City, Gansu Province using an SVC HR-1024 full-band ground feature spectroradiometer. The dataset encompasses spectral reflectance, measurement time, latitude and longitude, measurement height, number of measurements, operator, preprocessor, reviewer, solar conditions, cloud cover, air temperature, solar zenith angle, solar azimuth angle, observation angle and other relevant metadata. This dataset contains a total of 66 records.
