There are a number of reasons why land surveyors are turning to aerial drone technology for their mapping needs. First and foremost using drones can significantly reduce the time spent collecting accurate data over large distances. By acquiring faster data from the sky, drones allow you to gather millions of data points in one brief flight.
An aerial mapping drone turns a job that takes weeks to complete into a one that is finished in just a few days. Another benefit is the decreased exposure of staff to dangerous environments. An aerial survey means less time surveying teams spend on the ground, minimizing their risks when measuring sites such as mines, unstable slopes and transport routes.
Drones can quickly turn flight data into 2D orthomosaics (maps) and 3D models. The accuracy achieved by drones bridges the large gap between what is possible with satellites or manned aircraft and what is possible with terrestrial methods. Drones can quickly and easily collect and process valuable data for GIS databases in many fields, including; forestry, asset management, environmental protection, agriculture, humanitarian, remote sensing, oil and gas, etc.
