This is a list of free and open-source software for geological data handling and interpretation. The list is split into broad categories, depending on the intended use of the software and its scope of functionality. Notice that 'free and open-source' requires that the source code is available and users are given a free software license.
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.
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.
The Buckeye system relies on two major components: the electro-optical (EO) imaging system and the LIDAR system. The EO system utilizes a CCD camera and an embedded imaging computer to obtain the desired images while accounting for the movement of the aerial system to which it is attached.
Velodyne Lidar is a Silicon Valley–based lidar technology company, headquartered in San Jose, California. It was spun off from Velodyne Acoustics in 2016. [ 3 ] As of July 2020, the company has had about 300 customers. [ 4 ]
ISRO spin-off technologies are commercial products and services which have been developed with the help of the Indian Space Research Organisation (ISRO), through research and development, licensing of ISRO patents, use of ISRO facilities, technical assistance from ISRO personnel, or data from ISRO research.
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.

Lidar (/ ˈ l aɪ d ɑːr /, also LIDAR, an acronym of "light detection and ranging" [1] or "laser imaging, detection, and ranging" [2]) is a method for determining ranges by targeting an object or a surface with a laser and measuring the time for the reflected light to return to the receiver.
