The spatial distribution of the topographic change polygons across the states is shown in the figure below. Some noteworthy patterns seen on the map are a dense concentration of polygons in eastern Kentucky and southern West Virginia, a distinct cluster of polygons in northern Minnesota, several larger groups of polygons in Wyoming and southern Arizona, a concentration of polygons in the highly urbanized areas of coastal southern California, and an overall higher density of polygons in the eastern United States. Change polygons are located in all states except Rhode Island and the District of Columbia.

Significant Topographic Changes in the United States

The USGS has developed a national inventory of significant topographic changes based on seamless multitemporal elevation data and land cover data. The National Elevation Dataset (NED) and the Shuttle Radar Topography Mission (SRTM) data form a unique pair of seamless elevation datasets that can be used to detect and analyze 20th century topographic surface changes in the United States.
