Land Surveying Aerial Imaging Support
A successful development project begins with an accurate land survey, which is why it’s critical for organizations to capitalize on the latest in surveying technology. Unmanned aerial systems (UASs), or drones, are one example of a new technology that is delivering better results for land surveyors worldwide. Read on to learn the specific ways that adopting UAS to support surveying products can help.
Aerial Drones Cut Costs and Improve Efficiency- Traditional land-surveying methods require a significant amount of time and effort to achieve results. If a project covers a large area or includes rough terrain that surveyors would find difficult to traverse on land, then the situation is exacerbated. A slow, time-consuming land-surveying process is much more than mere inconvenience. When an organization has to wait for surveying to finish before it can proceed with the actual project work, then timelines for the project to become a profitable investment get pushed back. In addition, more hours worked by a surveyor equals more money coming out of the developer’s pockets.
With these thoughts in mind, it’s no wonder so many developers are looking for a better way. With UAV surveying, companies can save money and time by completing survey work faster. UAVs can cover large areas of terrain in a relatively short period of time, and because they operate in the air, they can cover all terrain in the same amount of time, no matter how dense or difficult for humans to traverse. As a result, companies get the surveying data they need, turned around quickly, so the project can proceed with fewer interruptions
Use Drones for 2D, 3D & Elevation Mapping
Using advanced techniques, our expert drone pilots can efficiently deliver highly accurate photogrammetry for different fields such as topographic mapping, architecture, engineering, manufacturing, quality control, police investigation and geology, as well as by archaeologists to quickly produce plans of large or complex sites. Thanks to the onboard GPS of the drone, typically our drones have an absolute error of only half a meter, though ground control points could be integrated to give centimeter precision to the absolute locations.
How do we do it
We use high megapixel cameras on stabilized camera mounts to deliver true georeferenced maps that are cost efficient and timely. Consider the cost or accuracy that would be associated with hiring helicopters or other aircraft that are supplied with the necessary photogrammetry equipment. The process is a matter of flying a drone from a waypoint to capture multiple overlapping photographs of the ground or model which will be pieced together to construct the 2D or 3D mapping or desired 3D model. This process would be virtually impossible to duplicate, let alone at the accuracy rate using a piloted aircraft.
