Definition of LIDAR:
Light Detection and Ranging (LIDAR) is active remote sensing which uses laser lights to strike features and record the reflected pulses to generate the 3D model of objects. Nowadays LIDAR data is widely used in different field. But the problem is, it is expensive and there are only few websites that provide access to download the data for free. Free LIDAR data are mostly from the United States area.
Mostly, LIDAR data is in the LAS format. To browse the LIDAR data you need specific extension for a software or a LIDAR software.

Open Topography is the public domain where users upload their data for public to have access of high quality topographic and bathymetry data. Open Topography system is based on the San Diego Supercomputer center at the University of California.
Process 1: Register as a user to download the point cloud data, non-register users can only download KMZ extension file, good for google earth only.
Process 2: Click on the red icon to download the LIDAR data.
