Interactive access to coastal change science and data for our Nation’s coasts. Information and products are organized within three coastal change hazard themes: 1) extreme storms, 2) shoreline change, and 3) sea-level rise. Each data item represents an individual research product, with some items grouped together as aggregates to show the breadth of the topic and make it easy to explore.

Structure datasets for the nation from The National Map
April 20, 2016

Structures Data

USGS data portray selected structures data, including the location and characteristics of manmade facilities. Characteristics consist of a structure's physical form (footprint), function, name, location, and detailed information about the structure. The types of structures collected are largely determined by the needs of the disaster planning and response and homeland security organizations.

Economic vulnerability to sea-level rise along the northern U.S. Gulf Coast

The northern Gulf of Mexico coast of the United States has been identified as highly vulnerable to sea-level rise, based on a combination of physical and societal factors. Vulnerability of human populations and infrastructure to projected increases in sea level is a critical area of uncertainty for communities in the extremely low-lying and flat...

“From the mountains to the coast, the southeastern U.S. contains ecosystems that harbor incredible biodiversity. Many of those ecosystems are already highly at risk from urbanization and other human land-use change. Identifying the ecosystems at risk from climate change will help inform conservation and management to ensure we don’t lose that biodiversity.” (Jennifer Constanza, report author)
