Surveying and Mapping

Applications Details of UAV in Surveying

 

Drones mean a quantum leap for surveying. They provide eyes that can reach and hover above specific sites. Their height and cameras can be adjusted remotely. And, equipped with sensors, they can measure, transmit and store data. Global positioning has created greater interest in Geographical Information Systems (GIS). GIS professionals provide a wide variety of land-related services like identifying property boundaries, subdividing land, and surveying construction sites for placement of buildings. They also produce topographic and hydrographic maps, volumetric calculations for stockpiles, and flood insurance maps, among other services.

Other benefits to surveying with drones include:

 

Disruption. The drone operator can work from a considerable distance and not worry about natural or artificial barriers to the sight lines.

 

 

• Imagery. Images are high resolution and serve a variety of users. They can be transmitted, shared and printed. Software can turn them into topographical maps, heatmaps and more.

 

• Risk. Drones present no safety risk for the operator and eliminates risks to ground and air personnel.

 

• Environment. Battery-operated, drones produce no toxic fumes.

Reduce field time and survey costs

 

Capturing topographic data with a drone is up to five times faster than with land-based methods and requires less manpower. With PPK geo-tagging, you also save time, as placing numerous GCPs is no longer necessary. You ultimately deliver your survey results faster and at a lower cost.

 

Provide accurate and exhaustive data

 

Total stations only measure individual points. One drone flight produces thousands of measurements, which can be represented in different formats (orthomosaic, point cloud, DTM, DSM, contour lines, etc). Each pixel of the produced map or point of the 3D model contains 3D geo-data.

 

Map otherwise inaccessible areas

 

An aerial mapping drone can take off and fly almost anywhere. You are no longer limited by unreachable areas, unsafe steep slopes or harsh terrain unsuitable for traditional measuring tools. You do not need to close down highways or train tracks. In fact, you can capture data during operation without an organizational overhead.
