Javedakar releases LiDAR Survey of forest areas for 10 states
Subject : Science & tech
Context : Minister for Environment, Forest and Climate Change, Shri Prakash Javadekar in a virtual event today released the Detailed Project Reports (DPRs) of LiDAR based survey of forest areas in ten states namely Assam, Bihar, Chhatisgarh, Goa, Jharkhand, Madhya Pradesh, Maharashtra, Manipur, Nagaland, and Tripura.
Concept :
LiDAR
- LiDAR (Light Detection and Ranging) is a remote sensing method that uses light in the form of a pulsed laser to measure ranges & variable distances.
- 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.
Applications:
- LiDAR is used for agriculture, hydrology and water management systems and geology-related applications.
- It is also used in archaeology.
