Spatial data to support the article 'Shoreline change on a tropical beach: the influence of beachrock and shore protection structures' that describes historical erosion and the effects of coastal structures and erosion abatement measures for Seven Mile Beach, Grand Cayman, Cayman Islands. This is largely data that was derived using the ArcGIS extension Digital Shoreline Analysis System (DSAS) https://www.usgs.gov/centers/whcmsc/science/digital-shoreline-analysis-system-dsas As the output of the DSAS extension are symbolized feature classes, an ArcGIS layer package (.lpk) is included. There is also a zip file containing other spatial data in shapefile format.支持论文《热带海滩岸线变化：海滩岩与护岸构筑物的影响》的空间数据集，该论文针对开曼群岛大开曼岛的七英里海滩，阐述了历史岸线侵蚀状况以及海岸构筑物与侵蚀缓解措施的实施效果。本数据集绝大多数基于ArcGIS扩展模块数字岸线分析系统（Digital Shoreline Analysis System，DSAS）生成，其官方网址为https://www.usgs.gov/centers/whcmsc/science/digital-shoreline-analysis-system-dsas。由于DSAS扩展模块的输出结果为符号化要素类，本数据集附带ArcGIS图层包（.lpk）。此外还包含一个压缩包，内含Shapefile格式的其他空间数据。
