Overview
This repository contains U.S. topographic data gathered by many groups using a variety of lidar sensors. Using the custom download for up to 1.5 billion points, users may search and select output by year, area, data provider, elevation product, projection, datum, and format. Output types include point clouds, digital elevation models, and contours. Requests are submitted to an automated system for custom processing, and a URL link is emailed to the user upon completion. For larger requests, such as full counties, the point cloud is available in LAZ format and geographic coordinates via a bulk download link. Data sets with “DEM” in the name will have a bulk download link to the data in their original projection and tiling.
