The TopoDrone-4Scight is an easy-to-use multi-rotor accurate mapping drone. It easily collects photogrammetric mapping data of unprecedented accuracy (20mm horizontal and better than 25mm vertical) for rapid integration into a wide range of industries including Surveying, Urban Mapping, Civil Engineering, Mining, Agriculture, Bridge and Dam Wall Mapping, Post Disaster Mapping and other industries.

What makes the TD-4Scight so unique is that there is no need for Ground Control Points –The UAV goes with PPK Direct Georeferencing Solution which logs all the high precision GPS satellites on board, synchronized to the nano-second of the camera shutter. This makes the TD-4Scight ideal if you need to map larger areas, when survey control needs to be cut to one or two points and/or the terrain is difficult to map (e.g. forests, coastal areas etc.).
