Unmanned Aerial Systems (UAS)
An Unmanned Aerial System consists of the Unmanned Aerial Vehicle (UAV) (for instance, a fixed wing or a rotary wing), the Ground-Based Controller, and the Communications system for the entire system to work. With these UAVs getting more affordable each passing day, it is no wonder that they are adopted for uses such as aerial mapping, digital surface modelling (DSM), digital terrain modelling (DTM), terrain analysis and many more.
At Aries Geomatics, our Unmanned Aerial System Services employ the use of either the Fixed Wing Drone or the Rotary Wing Drone, in accordance to the project requirements. For instance, the Fixed Wing Drone can cover a larger distance per flight, enabling the easy coverage of Vast Terrains or Green Corridors. It will be more suitable for agricultural, environmental and land surveying purposes. The Rotary Wing Drone, on the other hand, has a lesser coverage due to its speed, but it compensates with higher object resolution and the need for a relatively smaller take-off and landing area, which makes it suitable for more localised projects, especially in urban areas, like obtaining the Point Cloud Data of a cluster of buildings).
Generally, the data collection technology employed is either Photogrammetry or LiDAR (similar to the Terrestrial Laser Scanner). The 2 technologies are fundamentally very different, and have their own strengths in their respective areas. The project scope and requirements will very much determine which technology is most suitable for the desired output. However, one important aspect they have similar, is that they can both generate accurate Point Cloud data.
We at Aries Geomatics are committed to understanding and tailoring the best Unmanned Aerial System solution for your project needs. Do not hesitate to contact us for more information and we'll be happy to help!
