Light detection and ranging (lidar) mapping is an accepted method of generating precise and directly georeferenced spatial information about the shape and surface characteristics of the Earth.
The key of lidar design is the understanding of physical interactions and processes involved, the lidar simulations, and the choices of lidar type, configuration, arrangement, hardware and software to meet the
Building a LIDAR system can be made with either a high-speed analog-to-digital converter (ADC) or a time-to-digital converter (TDC). This reference design shows how to design the time measurement back-end for LIDAR based on a TDC

In radar, a single real aperture patch covers a large area, usually large enough to cover the whole target area of interest. In ladar, the target area must be imaged by “mosaicing” real aperture patches together. Gathering data does not make an image, or information. What a lidar detects? Wind Sensing bounces laser energy off of aerosols or air.

Laser Detection and Ranging (LiDAR) systems possess the capability to generate high-resolution three-dimensional (3D) data of indoor environments.
Principles of Airborne LiDAR –Flight Planning - cannot penetrate clouds - are often flown at night - overlap of 30 to 50% in steeper terrain - multiple passes at different angles in urban areas (to avoid LiDAR “shadow”) - flying elevation typically 200 to 300 meters (higher in urban areas)
