Drones have proven to be a revolutionary technology in the field of surveying and mapping. What makes GPS enabled UAVs increasingly appealing to Surveyors is their ability to produce high resolution data at an accuracy close to 1 centimetre and at reasonable costs. Due to their lower flying heights UAVs contribute significantly in reducing risks and makes it possible to survey hazardous and inaccessible areas in a safe manner.
The two most popular methods of data acquisition through UAVs is Photogrammetry & LiDAR methods which use different kinds of sensors for capturing spatial information. While both methods generate data with high accuracies LiDAR is considered superior to Photogrammetry due to its ability to penetrate vegetation and similar is the case when surveying narrow objects.
