2018年8月山西省阳曲县荞麦反射率数据集

本数据集为2018年8月26日山西省阳曲县荞麦反射率数据集，来源于河南山西两省典型农作物为主，在作物生长季节测量了玉米、小麦、大豆、花生、水稻、谷子等典型农作物光谱，测量时选些地势平坦，种植面积较大的区域以样方进行地物波谱及其配套参数的测量。该数据集可为作物生长模型提供输入数据，也可支持高分辨率遥感影像地表参数的反演及遥感产品验证，尺度转换和尺度效应等研究。该数据集采用面向测绘地物波谱的分类体系，按照统一的规范进行波谱及其配套参数质量控制，形成测绘地物波谱本底数据库的特色数据集，用户可在波谱库官方网站免费下载，实现数据集共享。本数据集共有光谱25条。

This dataset is the buckwheat reflectance dataset collected in Yangqu County, Shanxi Province on August 26, 2018. Mainly sourced from typical crops in Henan and Shanxi Provinces, the spectra of typical crops including maize, wheat, soybean, peanut, rice, foxtail millet, etc., were measured during crop growing seasons. During the measurement, plots with flat terrain and large planting areas were selected to collect surface feature spectra and their supporting parameters. This dataset can provide input data for crop growth models, and also support research such as the inversion of surface parameters from high-resolution remote sensing images, validation of remote sensing products, scale transformation, and scale effects. This dataset adopts a classification system oriented towards surveying and mapping surface feature spectra. It conducts quality control on spectra and their supporting parameters in accordance with unified specifications, forming a characteristic dataset of the surveying and mapping surface feature spectra background database. Users can download it for free from the official website of the spectral library to realize dataset sharing. A total of 25 spectral samples are included in this dataset.
