2018年河南省焦作市温县山药种植分布图

本数据产品为2018年河南省焦作市温县山药种植分布图，使用高分辨率多光谱遥感影像结合纹理特征和光谱特征，结合地面采样点使用机器学习方法综合分析河南省焦作市温县山药的种植分布制作出图，并进一步通过NDVI等指数计算山药长势。

This data product is the 2018 planting distribution map of Chinese yams in Wen County, Jiaozuo City, Henan Province, China. The map was generated via a comprehensive analysis of the yam planting distribution in the target area, which integrated high-resolution multispectral remote sensing imagery, texture features, spectral features, ground sampling points, and machine learning methods. Additionally, the growth status of the yams was assessed using indices such as the Normalized Difference Vegetation Index (NDVI).
