2018年8月山西省谷子反射率数据集

本数据集为2018年8月23日-27日山西省谷子反射率数据集，其中23日为山西省晋城市高平市；24日为山西省晋城市武乡县；25日为山西省晋中市寿阳县；26日为山西省太原市阳曲县；27日为山西省吕梁市石楼县；来源于河南山西两省典型农作物为主。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115条。

This dataset is the foxtail millet reflectance dataset of Shanxi Province collected between August 23 and 27, 2018. The collection sites were as follows: Gaoping City, Jincheng City, Shanxi Province on August 23; Wuxiang County, Jincheng City, Shanxi Province on August 24; Shouyang County, Jinzhong City, Shanxi Province on August 25; Yangqu County, Taiyuan City, Shanxi Province on August 26; and Shilou County, Lvliang City, Shanxi Province on August 27. This dataset is mainly sourced from typical crops in Henan and Shanxi Provinces. This dataset can provide input data for crop growth models, and support research on surface parameter inversion from high-resolution remote sensing images, remote sensing product validation, as well as scale transformation and scale effect studies. This dataset adopts a classification system oriented to surveying and mapping ground object spectra, carries out quality control over the spectra and their supporting parameters in line with unified technical specifications, and constitutes a characteristic dataset of the background database for surveying and mapping ground object spectra. Users can download this dataset free of charge from the official website of the spectral database to achieve dataset sharing. A total of 115 spectral records are included in this dataset.
