2018-2020年黄河季节性变化卫星影像提取图

本数据产品针对黄河流域河南段黄河流域水域及沿岸生态进行分析，主要分析内容为2018-2019年黄河水面季节性变化，黄河滩地结节性变化和黄河固定滩地分析提取，黄河沿岸土地利用分析。主要解译手段为结合sar卫星影像和多光谱卫星影像的水体特征分析黄河水面季节性变化，使用多时相多光谱影像结合黄河水面变化分析、黄河滩地变化提取黄河固定滩地，使用多光谱遥感影像分析提取黄河沿岸土地利用。

This data product targets the analysis of waters and riparian ecosystems of the Henan section of the Yellow River Basin. The primary analysis contents cover the seasonal variation of the Yellow River's water surface between 2018 and 2019, the nodular changes of the Yellow River's floodplains, the analysis and extraction of the Yellow River's fixed floodplains, and the analysis of land use along the Yellow River. The main interpretation approaches include: analyzing the seasonal variation of the Yellow River's water surface via water body feature extraction using both SAR satellite images and multispectral satellite images; extracting the Yellow River's fixed floodplains by combining multi-temporal multispectral images with the analysis of the Yellow River's water surface changes and floodplain variations; and analyzing and extracting land use along the Yellow River using multispectral remote sensing images.
