National Lidar Dataset (United States)

The National Lidar Dataset (United States) is a special type of map that helps people find their way around the country. It uses special laser technology to map the terrain and land features of the US. It helps people know what kind of roads, streets, and buildings are in an area. It also helps tell how far apart the cities and towns are, and how much elevation there is between them. This helps people plan trips, and find their way to places that are far away, using the most direct paths.
