Description: This resource was developed by the U.S. Geological Survey (USGS) in partnership with Esri and the Marine Biodiversity Observation Network (MBON). The underlying data are 4 million 1 km or shorter coastal segments, each of which is attributed with values from ten ecological settings variables representing the adjacent ocean, the adjacent land, and the coastline itself. The 4 million coastal segments were classified into 81,000 coastal segment units (CSUs) using the Coastal and Marine Ecosystem Classification Standard (CMECS). Each distinct CSU is a segment with a unique combination of the classes of values of the ten ecological settings variables. The 4 million segments were also clustered into a set of 16 global groups of coastlines which are similar in the aggregate ecological setting described by the ten variables. The complete set of methodological details and results from the global coastline segmentation analysis are available in Sayre et al. (2021). The geospatial linework used for the global segmentation, classification, and clustering is the same Global Shoreline Vector (GSV) data used in the companion tool we developed for exploring the location, shape and size, and name of the islands of the planet. The derivation of the GSV from 30 m spatial resolution satellite imagery is described in Sayre et al. (2018). Sayre, R., K. Butler, K. VanGraafeiland, S. Breyer, D. Wright, C. Frye, D. Karagulle, M.
