LIDAR Technology:
- Light detection and ranging is a method for determining ranges (variable distance) by targeting an object with a laser and measuring the time for the reflected light to return to the receiver. The light pulses when combined with other data help in generating high-resolution, accurate 3D information of the object.
Applications in different fields:
- Agriculture:
Optimal utilization of fertilizer, insect monitoring, detecting variance in production are some of the applications
- Forestry:
Canopy heights, biomass measurements, and leaf area can all be studied using airborne lidar systems.
- Geography:
The lidar abilities to detect subtle topographic features such as river terraces and river channel banks, glacial landforms etc.
- Automobiles:
Autonomous vehicles may use lidar for obstacle detection and avoidance to navigate safely through environments.
- Law and Order regulation:
Lidar speed guns are used by the police to measure the speed of vehicles for speed limit enforcement purposes.
- Plant species classification and archaeological findings can be done with ease
LIDAR and Indian projects:
- Recently the Ministry of Environment and Forests released a survey of forest areas in ten states based on LIDAR technology.
- Recently the Andhra Pradesh government deployed LIDAR technology for effective implementation of its fibernet project.
- National High Speed Rail Corporation Limited is adopting LIDAR survey technique for conducting ground survey for the proposed Delhi-Varanasi High Speed Rail (HSR) corridor.
Conclusion:
- Given the multidimensional applications of LIDAR technology, it is obvious that the state of the art technology will play a key role in India’s future.
