2019年山东省部分地市玉米种植分布图

本数据产品为2019年山东省部分地市玉米种植分布情况，包括济宁、泰安、东营、菏泽等多地市。本项目内容主要为使用中等分辨率多光谱影像，结合实地查勘通过监督分类方法分析影像光谱特征和纹理信息，提取玉米通过NDVI等遥感指数，分析生长长势。

This data product provides the corn planting distribution in some prefecture-level cities of Shandong Province in 2019, covering cities including Jining, Tai'an, Dongying, Heze and others. This project mainly uses medium-resolution multispectral imagery combined with field surveys, analyzes the spectral features and texture information of the images via supervised classification methods, extracts corn planting areas through remote sensing indices such as NDVI, and analyzes the growth status of corn.
