Unmanned Aerial Vehicles – UAV’s are becoming more prevalent in the field of geospatial data collection. They operate by carrying out various tasks such as mapping, surveying, and reconnaissance.
UAVs are the latest generation of unmanned aircraft that are capable of capturing more detailed images and data without leaving their base. Their ability to collect data has garnered wide acceptance in various applications.
UAVs can get closer to the targets without being hindered by the weather conditions. They can also fly lower and faster than manned aircraft. The lidar utilizes laser light to map the environment. It can also identify vegetation and other minor obstacles. A point cloud is a massive database containing millions of elevation data points. These points help map out the terrain and identify objects within it.
Another benefit of UAVs is their speed. They can be deployed in days or weeks, which is faster than traditional methods of surveying. This saves time and costs and eliminates the need for in-person visits to the site.
UAV Applications: A class of data can be collected by appending complex sensors and cams on UAVs, including:
- Topographic lidar for mapping areas.
- Heat cameras for examining buildings, solar tracks, electrical services, and pipelines to distinguish deterioration, incompetence, punctures, or hot spots.
- Multispectral and hyperspectral description for detecting targets and identifying elements, such as various classes of trees in nature administration apps.
- Orthomosaic imagery, which is a photomontage of several pictures in which geometric deformity has been improved to accommodate a seamless miscellany dataset.
- Topo-bathymetric sensors for getting near the coast or riverine landforms.
UAVs are being used victoriously in various projects beyond a variety of systems, This data can then be combined with other data sources to produce 3D drawings and surfaces, as well as build models for designing structures and infrastructures. For instance, the City of Imperial Beach, California, used UAVs to collect aerial data for a drainage study. The project, which involved surveying almost a hundred acres of urban roads, was made possible through the use of drones.
In another case, a drone was used to survey rural roadways in Idaho. The project involved surveying 800 acres of roadwork in Rexburg. UAVs are becoming more sophisticated tools for mapping the world. They can capture images of fixed objects and landscapes and provide high-quality data sets.
