Lidar, which stands for light detection and variety, is a remote sensing technology that uses laser pulses to measure distances to the Earth’s surface or other objects. It works by emitting laser pulses and then measuring the time it takes for the reflected light to return to the sensor. This data is used to create detailed three-dimensional maps or models of the surveyed area, capturing precise elevation information and surface features with high precision.
Lidar finds applications in various fields, including forestry, urban planning, archaeology, environmental monitoring, infrastructure development and disaster management.
Essentially, LiDAR technology enables precise mapping and monitoring of terrain, infrastructure and vegetation by providing detailed elevation data and 3D models. It is particularly valuable in scenarios where accurate topographic information is essential for planning, analysis and decision-making processes.
Industries and sectors that benefit from LiDAR include agriculture, land surveying, construction, transportation (road and railway planning), flood risk assessment, and natural resource management.
People use lidar for its ability to generate highly accurate and detailed maps of terrain and objects, which are crucial for various applications requiring precise spatial data. The technology enables rapid data collection over large areas, providing comprehensive information on land characteristics, vegetation structure and building morphology.
By offering detailed 3D models and elevation maps, LiDAR supports better decision-making in urban development, infrastructure design, environmental conservation and disaster response planning.
In India, LiDAR technology is used across various sectors to address specific needs and challenges. Applications include urban planning and development, where accurate elevation data is used in infrastructure design, flood risk assessment and smart city initiatives.
LiDAR is also used in forestry and agriculture to monitor vegetation health, evaluate land use patterns, and optimize crop management practices. Additionally, LiDAR plays a role in archaeological investigations, cultural heritage preservation and natural resource management, contributing to sustainable development and environmental conservation efforts across the country
