Bollywood Actor Ajay Devgan , who met AP CM Chandrababu Naidu at CM Camp office in Vijayawada, has proposed the latest Lidar (Light Detection and Ranging) technology for monitoring different projects. While Naidu welcomed to use the technology for monitoring irrigation and constructions projects.
Lidar is a surveying technology that measures distance by illuminating a target with a laser light. Lidar exists as an acronym of Light Detection And Ranging, and was originally created as a portmanteau of “light” and “radar”.
It uses light in the form of a pulsed laser to measure ranges (variable distances) to the Earth. These light pulses—combined with other data recorded by the airborne system— generate precise, three-dimensional information about the shape of the Earth and its surface characteristics.
A LIDAR instrument principally consists of a laser, a scanner, and a specialized GPS receiver. Airplanes and helicopters are the most commonly used platforms for acquiring LIDAR data over broad areas.
