资源简介：
This resource is an ESRI file geodatabase that contains floodplains for the continental United States. The geodatabase contains one feature class for each state. This is the the first version of the data which also includes wetlands and other water bodies as floodplains. More details on how the floodplains are extracted from the SSURGO data can be found in the following JAWRA article: Sangwan, Nikhil, and V. Merwade, A faster and economical approach to floodplain mapping by using soil information, Journal of American Water Resources Association, 51(5): 1286-1304. (2015)
本资源为一款包含美国大陆洪泛区的 ESRI 文件地理数据库。地理数据库中针对每个州均包含一个要素类。此为数据的首个版本，其中亦包含湿地及其他水体作为洪泛区。有关如何从 SSURGO 数据中提取洪泛区的更详细信息，可参考以下 JAWRA 文章：Sangwan, Nikhil，及V. Merwade，通过利用土壤信息实现洪泛区测绘的快速且经济的方法，美国水资源协会杂志，第51卷第5期，第1286-1304页。（2015年）
