Currently, the best source for nationwide LiDAR availability from public sources is the United States Interagency Elevation Inventory (USIEI). [1] The USIEI is a collaborative effort of NOAA and the U.S. Geological Survey, with contributions from the Federal Emergency Management Agency, the Natural Resources Conservation Service, the US Army Corps of Engineers, and the National Park Service.
A national lidar dataset refers to a high-resolution lidar dataset comprising most—and ideally all—of a nation's terrain. Datasets of this type typically meet specified quality standards and are publicly available for free (or at nominal cost) in one or more uniform formats from government or academic sources.
The LAS (LASer) format is a file format designed for the interchange and archiving of lidar point cloud data. It is an open, binary format specified by the American Society for Photogrammetry and Remote Sensing (ASPRS). The format is widely used [1] and regarded as an industry standard for lidar data.

Cirrus features raw data from Luminar's high-performance lidar sensors, which accurately detect objects ahead of the car out to 250 meters away. "By making these resources publicly available, we ...
Lidar data helped researchers find thousands of Maya structures in Mexico. ... "That's the point of open data is to say, 'Look, it's open to everybody, so make use of it,'" he said.

libLAS is a library for reading and writing geospatial data encoded in the ASPRS laser (LAS) file format, versions 1.0, 1.1 and 1.2. LAS-formatted data is heavily used in lidar processing operations. The LAS format is a sequential binary format used to store data from sensors and as intermediate processing storage by some applications.
