Tidal Flats in Florida

Tidal flats are non-vegetated areas of sand or mud protected from wave action and composed primarily of mud transported by tidal channels. An important characteristic of the tidal flat environment is its alternating tidal cycle of submergence and exposure to the atmosphere. This GIS data set was created to show a statewide representation of unvegetated tidal flats, compiled from the best available sources. The sources included individual seagrass mapping studies and National Wetlands Inventory (NWI) data for Florida. The NWI was ERASEd using more recent data sources that showed some areas were indeed vegetated. See Source Information for more details on how each source was used.潮滩（tidal flats）为免受波浪作用影响的沙质或泥质无植被区域，其主要由潮沟搬运的泥沙构成。潮滩环境的重要特征之一，是周期性交替的潮汐淹没与大气暴露循环。本地理信息系统（GIS）数据集旨在呈现全州范围内的无植被潮滩分布，数据整合自当前可获取的最优数据源。数据源涵盖独立海草测绘研究成果，以及佛罗里达州的国家湿地清单（National Wetlands Inventory, NWI）数据。研究团队已借助可证实部分区域确有植被覆盖的最新数据源，对该国家湿地清单数据进行了修正，剔除了原标注中错误的无植被区域。如需了解各数据源的具体使用细节，可查阅「数据源说明」。
