Data from: Global Coastal Protection Strategies for Erosion from Open Street Maps

Data was retrieved from OpenStreetMap (OSM) along the global coastal areas on coastal adaptation structuresz including groynes, jetties/breakwaters, and dykes/seawalls. The data presented here is only about the locations of where these structures can be found. There is no information on the characteristics of the structures. OSM is a free, open geographic database updated and maintained by a community of volunteers via open collaboration. Contributors collect data from surveys, trace from aerial imagery and also import from other freely licensed geodata sources. Therefore, the data may be unavailable in areas where the community has not uploaded such data onto the map due to limited technology and understanding of the approach.
