Drone photogrammetry offers a fast, cost-effective and often safer method for Lin & Associates to collect aerial imagery and scan points required for accurate mapping, verification, and site plans. Photogrammetry transforms 2D images into 3D models, allowing a 3-dimension view, helping to interpret the surveyed area more in depth. With our licensed drone pilot, L&A has the ability to establish scan points around the building or area in question so that there is a clear line of sight to the columns which were surveyed.
Employee safety is one of the many benefits of using drone photogrammetry for land surveying. Using drones helps avoid dangerous terrain, and hazardous areas, helping to reduce the risk of injury significantly. Since drones are able to capture images of a large area and elevation, it keeps employees from having to physically map the area themselves, including carrying heavy equipment from location to location.
Timing and budget are another benefit of using drones. Drones are able to capture more area, which increases efficiency and reduces cost.
Recent representative projects on which L&A has provided quality drone photogrammetry services include: Sound Transit LINK Light Rail (Federal Way Link, I-90 East Link, Tacoma Link), Seattle DOT Northgate Pedestrian Bridge, Seattle DOT NE 45th Street Viaduct, King County South Treatment Plant, King County North Lake Sammamish, and Seattle Public Utilities South Transfer Station. To date, L&A has provided numerous types of drone photogrammetry, including treatment plants, roadways, trails, railways, private properties, drainage facilities, and power substations. As the majority of projects are performed for public agencies and in Washington State, all team members are familiar with the relevant standards needed to successfully utilize drone photogrammetry technology.
