Drone surveying is booming in the space of geospatial data collection. Using drones one can carry out topographic surveying with highly accurate and non-compensatable quality of traditional surveying methods. The primary advantages of drone surveys include less time consumption, cost-effectiveness, reduced usage of manpower that can efficiently work in atmospheric conditions like cloud cover.

What is a Drone survey?

Drone Survey is all about collecting geospatial data through unmanned aerial vehicles (UAV). Drones can fly at a lower altitude and making high-resolution data with definite accuracy and are used to capture aerial orthophotos using downward-facing sensors. Some examples of downward-facing sensors are RGB or multispectral cameras and LIDAR payloads. RGB or multispectral cameras are used to capture the ground photographs from different angles. Each photo captured is Geotagged which means the image is tagged with real-world coordinates).

From the collected data, using photogrammetric software one can create orthomosaic georeferenced aerial photographs, elevation models, terrain models, 3D models for the study area. These data are used to extract geospatial information for highly accurate distance, Volumetric analysis, future infrastructure planning, etc.,

Sensors used in Drone Survey

Different types of sensors are used to collect a variety of information and record the changes in the environment that are connected by drones. In drones, sensors help to neglect collision, Navigation, altitude finding, etc.
