资源简介：
A new 30 meter resolution polygon data layer of the islands of the United States, with associated attributes describing key physical and conservation geography characteristics. Islands were grouped into a three-tiered hierarchy of island provinces (12), island regions (28), and individual islands (a total of 19,023 islands were extracted). Islands were classified as estuarine vs non-estuarine, and nearshore vs. offshore.
