2018年3月-4月河南省新郑市小麦反射率数据集

本数据集为2018年3月29日和4月29日河南省新郑市赵家寨小麦反射率数据集；来源于河南山西两省典型农作物为主，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45条。

This dataset comprises wheat reflectance measurements collected in Zhaozhaizhai, Xinzheng City, Henan Province, on March 29 and April 29, 2018. Field measurements were conducted targeting typical crops in Henan and Shanxi provinces, with plots featuring flat terrain and large planting areas selected for the acquisition of surface feature spectra and their ancillary parameters via the quadrat sampling method. This dataset can serve as input data for crop growth models, and support research related to high-resolution remote sensing image surface parameter inversion, remote sensing product validation, scale transformation, and scale effect. Adopting a classification system tailored for surveying and mapping surface feature spectra, this dataset underwent quality control of spectra and ancillary parameters in accordance with unified standards, forming a characteristic dataset within the surveying and mapping surface feature spectrum background database. Users can freely download this dataset from the official website of the spectral library to enable open sharing of the dataset. In total, 45 spectral records are included in this dataset.
