Applications of Drone Surveying

The main applications of drone surveying come in:

Land surveying
Precise measurements
Land management and development
Volumetric measurements
Slope monitoring
Urban planning
1. Land Surveying/Cartography
Drone surveying generates high-resolution orthomosaic maps and 3D types of areas to generate accurate cadastral maps. It provides information on a site with low-quality/outdated/no data available.

2.  asbestos surveyors  and Development
The aerial images obtained from drones simplify topographic surveys for land management and planning. It facilitates site scouting, allotment planning, design, and the final construction of roads, buildings, and utilities. Furthermore, the data is used for pre-construction engineering studies transferred to CAD or BIM software to work with 3D models.

3. Precise Measurements
The surveyors can perform highly-accurate distance and surface measurements using the high-resolution orthomosaic photos from drone surveying.

4. Volumetric Measurements
The images obtained from drone surveying can be utilized in 3D mapping software, from which volumetric measurements are obtained. The technique is used primarily for calculating stocks in mines and quarries for inventory or monitoring purposes.
5. Slope Monitoring
The DTMs and DSMs generated by drone imagery and GIS analysis enable the extraction of slope measurements. Moreover, in a few site conditions, the orthomosaic maps are generated at different times to detect changes in the planet earth?s movement and measurement of velocity. This technique, hence, helps in slope monitoring for landslide mitigation and prevention, for example, predicting landslides, preventing potential harm to roads, railways, bridges, etc.

6. Urban Planning
Drone surveys help urban planners collect up-to-date data of a complex urban area quickly using less staff to review the prevailing social and environmental conditions of the sites. This makes the planning stage of the development of an urban area easier.
