黄河三角洲1：10万不行河流路河口海岸潮滩范围（2000-2015年）

2000年、2007年和2015年3个年份的黄河三角洲北部不行河流路河口海岸潮滩的范围，包括潮下带、潮上带和潮间带。下载历史遥感影像，提取一年中所有遥感影像的水边线，采用自然断点发找到每个断面与高低潮线的交汇点，提取所有断面上的特征点，连接形成潮滩范围。遥感数据处理采用ENVI5.3软件，水边线平均位置采用ArcGIS插件DSAS分析得到。

The dataset encompasses the tidal flat extents in the northern non-riverine estuarine coast of the Yellow River Delta for three years: 2000, 2007 and 2015, covering the subtidal, supratidal and intertidal zones. Historical remote sensing images were downloaded, and waterlines from all available remote sensing images for each year were extracted. The natural breaks method was used to identify the intersection points between each transect and the high and low tide lines, then feature points on all transects were extracted and connected to delineate the tidal flat extents. Remote sensing data processing was performed using ENVI 5.3 software, and the average positions of the waterlines were derived via analysis with the ArcGIS plugin DSAS.
