LIDAR stands for Light Detection And Ranging. It can be functionally defined as the integration of three technologies into a single system capable of obtaining data to produce digital elevation models. The three technologies are combined to produce a digital elevation model of laser, inertial navigation system and global positioning system.

LIDAR mapping, therefore, refers to the use of remote sensing technology to create high-resolution maps. The digital elevation map created by LIDAR equipment is usually placed on the plane. This technology is applied in various fields such as geography, archaeology, and seismology.
These measures optical remote sensing technology and the characteristics of scattered light information of a distant target. The distance to the target or object is measured using the time delay between the transmitted pulse and the signal due to the reflected and detected.
LIDAR uses electromagnetic wavelengths shorter visible and close in range to the infrared. Therefore, it is possible to capture images of objects or features of the same size to the wavelength. LIDAR equipped gadgets like robots have the ability to build a map and by obstacles pass.
LIDAR survey also suitable to produce accurate elevation data for the construction of infrastructure projects and new engineering. It is very important for planning. Also, it can be used by engineers to model scenarios in selecting the best location for construction.
There are private companies and academic institutions that support the work of collecting, processing and archiving of LIDAR data sets. such organizations collect and distribute LiDAR data for the purposes of research and education. This data is very useful in the field of geosciences and ecology.
