Surveying & Mapping

Drone technology is widely use in Industries like Mining, Power, Highway, Railway, Critical Infrastructure, Urban & Regional Planning etc.
Surveying & Mapping with a drone offers enormous potential to GIS professionals.
Using drone technology, it is possible to carry out topographic surveys with high quality & highly accurate measurements collected in a fraction of the time. This substantially reduces the cost and time of a site survey.

What is Drone Survey?

A drone survey refers to the use of a drone, or unmanned aerial vehicle (UAV), to capture aerial data with downward-facing RGB camera. During a drone survey the ground is photographed several times from different angles, with number of overlapped images and each image is geo-tagged.
From this data, a photogrammetry software can create geo-referenced orthomosaics, elevation models or 3D models of the project area. These maps can also be used to extract information such as highly-accurate distances or volumetric measurements.
Unlike manned aircraft or satellite imagery, drones can fly at a much lower altitude, making the generation of high-resolution, high-accuracy data, much faster, less expensive and independent of atmospheric conditions such as cloud cover.

Uses of Drone in Surveying

Land Surveying

Survey drones generate high-resolution orthomosaics and detailed 3D models of areas where low-quality, outdated or even no data, are available. They thus enable high-accuracy cadastral maps to be produced quickly and easily, even in complex or difficult to access environments.
Surveyors can also extract features from the images, such as signs, curbs, electric arrangements, road markers, fire hydrants, communication towers, Buildings, Open lands and drains.
After post-processing with a photogrammetry software, these same images can produce very detailed elevation models, contour lines and break lines, as well as 3D reconstructions of land sites or buildings.
