北方土壤室内测量反射率数据集

在北方地区采集具有代表性的土样标本，在室内测量反射率，所有仪器为ASD Fieldspec 3和ASD Fieldspec 4 Hi-Res光谱仪（波长范围均为350nm-2500nm），土壤类别包括草甸土、黑土、黑钙土、风沙土、棕壤等。数据内容包括光谱反射率、测量时间、经纬度、测量次数、测量人、预处理人、审核人。数据集共215条记录。

Representative soil samples were collected from northern regions. Their spectral reflectance was measured in a laboratory using ASD Fieldspec 3 and ASD Fieldspec 4 Hi-Res spectrometers, both with a wavelength range of 350 nm to 2500 nm. The soil types covered include meadow soil, black soil, chernozem, aeolian sandy soil, and brown earth, among others. The dataset includes spectral reflectance, measurement time, latitude and longitude, number of measurements, operator, preprocessing personnel, and reviewing personnel. There are 215 records in total for this dataset.
