LiDAR, which stands for Light Detection and Ranging, is a remote sensing technology used to measure distances using laser pulses. By emitting thousands of laser signals per second and measuring the time it takes for the signals to return, LiDAR systems can create highly accurate three-dimensional representations of the Earth’s surface.
LiDAR technology is widely used in geospatial mapping, infrastructure development, forestry analysis, and environmental monitoring. The ability of LiDAR to capture millions of spatial data points allows professionals to generate extremely detailed terrain models and digital surface maps.
One of the most powerful features of LiDAR technology is its ability to capture ground elevation even in areas covered by dense vegetation. This capability makes LiDAR particularly useful in forest mapping, flood modelling, and terrain analysis where traditional survey methods may face limitations.
Common applications of LiDAR technology include:
- High-resolution terrain mapping
- Infrastructure and urban modelling
- Flood risk analysis and environmental monitoring
- Transportation and road corridor mapping
With the rapid development of airborne LiDAR systems and drone-mounted sensors, the technology has become more accessible and efficient. Today, LiDAR plays a vital role in producing accurate geospatial datasets that support large-scale planning and engineering projects.
