2020年中国大陆岸线数据集

数据文件按照ArcGIS支持的Coverage、Shapefile和Geodatabase三种格式存储，均为矢量线要素数据。数据集使用说明：1、平均大潮高潮线与遥感水边线有很大差异，本研究是针对于一年之内较长时期的“平均大潮高潮线”；2、大陆海岸线信息具有一定的敏感性，不恰当的使用可能会造成某些形式以及不同程度的不良影响；3、本数据集生产的初衷是服务于学术研究目的及用途，不建议将其扩展至其他用途；4、本数据集的数据源空间分辨率较低（30m卫星影像），数据产品比较适合于较大空间尺度的研究区，因此，不建议将其用于小尺度研究区的相关研究。

All data files are stored in three formats supported by ArcGIS: Coverage, Shapefile, and Geodatabase, all of which are vector line feature data.
Dataset Usage Instructions:
1. There is a significant difference between the Mean Spring High Water (MSHW) line and the remote sensing water edge line. This study specifically targets the "Mean Spring High Water line" over a relatively long period within one year.
2. The continental coastline information has certain sensitivity. Improper use may cause adverse effects in various forms and to varying degrees.
3. The original intention of developing this dataset is to serve academic research purposes only, and it is not recommended to extend its application to other purposes.
4. The data source of this dataset has a relatively low spatial resolution (30-meter satellite imagery). Therefore, the data product is more suitable for study areas with large spatial scales, and it is not recommended to use it for relevant studies of small-scale study areas.
