At Metatek, we collaborate with various clients and partners in subsurface geophysics exploration. Amongst other methods, we are heavily involved in both LiDAR and Radar surveying. These two can be confused and often people ask us – What are the differences between LiDAR and Radar surveys?
In this short insight, we discuss the basic differences between LiDAR and Radar surveys and where you might choose to use each one.
In the realm of remote sensing and spatial analysis, two prominent technologies stand out: Lidar (Light Detection and Ranging) and Radar (Radio Detection and Ranging). Let us explore their key differences and applications:
One of the main differences between LiDAR and Radar surveys is the technology they use.
Lidar is an optical remote sensing technology that uses pulsed laser light to measure distances. It excels in high-precision and detailed imaging.
Radar on the other hand, utilises radio waves. While it is less precise compared to Lidar, it performs better in adverse weather conditions and over longer distances.
So, depending on the precision you require and the weather that is expected in the area you are surveying, you may be leaning more towards a particular technology.
Another difference between LiDAR and Radar surveys is the level of accuracy they offer.
Lidar offers higher precision in object detection and mapping.
Radar is less precise compared to Lidar but compensates with its longer range.
Depending on the size of the area required for your survey and the accuracy level, you may have a survey type that is better suited.
Another consideration you should take into account when determining which technology is better for your application is the weather that you are likely to encounter during the surveying process.
Lidar can be affected by atmospheric conditions like fog and rain.
Radar is more robust against adverse weather conditions.
Because of the discussed differences between LiDAR and Radar surveys, they are suited to different applications.
Lidar is widely used in topographical mapping, autonomous vehicles, and for uncovering archaeological sites.
Radar: Applied in weather forecasting, aviation, and military surveillance
