UAVs have become more reliable and easier to work with: from programming flight paths to installing additional equipment on board, UAV applications are no longer confined to a limited group of specialists.įor a survey flight, your UAV will need to have installed: a high-resolution camera and a high-end GNSS receiver module. Improvements in Unmanned Aerial Vehicle (UAV) technology combined with more compact high-end Global Navigation Satellite Systems (GNSS) receivers means that you no longer have to compromise on precision to measure in those hard-to-reach areas. A new ground control point configurations is introduced in this study as a generic approach in unmanned aerial vehicle photogrammetric block. Still feeling confident? You should and here’s why. To make the marking process as simple as possible, we recommend one of three types of GCP targets: square, diagonal, and Aeropoints. Throw in the fact that the area you have to survey is in a quarry which has been closed off due to a recent landslide. The clustering of data is one of the most important and challenging topics in data science. Lucia Absalom Bautista, Timotej Hrga, Janez Povh, Shudian Zhao.

Feeling confident? How about a few hundred points spread over 7.5 hectares (18.53 acres) and the job has to be done in one afternoon. Ground truth clustering is not the optimum clustering. You’ve been asked to survey some points on the ground with centimetre-level accuracy.
