OMNNI provides numerous aerial imagery services, both in support of our projects and for our clients. Unmanned Aerial Vehicles (UAVs) – commonly known as “drones” – are becoming an important component for documenting engineering projects, especially during construction. They are also being used to view real estate, enhance marketing efforts and record everyday life. OMNNI provides the following services:
UAVs provide the opportunity to take photographs from angles that were previously unavailable or impractical for most photographers. Photos can now be acquired anywhere from ground level to 400 feet above the surface. This provides the opportunity to minimize interference from trees and other obstacles and can provide dramatic compositions.
Aerial imagery is commonly used to document changing conditions at construction sites, and to provide comprehensive photos for reports and marketing materials. In addition, UAVs can safely obtain photographs of areas that would typically be hazardous for humans to access for inspection, including bridges and rooftops.
OMNNI can capture video at resolutions up to 4K, which is suitable for even the largest displays. By incorporating changes in altitude, the possibilities for video composition are greatly expanded. Videos are commonly used to document pre-construction conditions, construction progress, and the finished project. Aerial cinematography is an effective presentation tool when inserted into traditional video presentations.
From a construction/engineering approach, UAV video can be used to conduct and document routine inspections more efficiently than in-person inspections. Long stretches of perimeter fencing, silt fence, access roads, and other features that require frequent inspections can be flown in an automated sequence, with the results documented on video. The video from the flight can also be streamed live online for additional office staff to view in real time.

Orthomosaic Imagery, Topography and Volume Calculations
Multiple aerial images of large tracts of land can be stitched together into one overall image, known as an orthomosaic. These orthomosaic images can then be used as a basemap that reflects current conditions, or as a way to document changes to a site over time. The imagery collection process using the UAV is very efficient – 40 acres can be scanned in less than 10 minutes. The resulting imagery can have resolutions of ¼-inch per pixel or finer, if needed.
The same imagery that is collected for generating orthomosaic images can be used to generate accurate 3-dimensional representations of the ground surface. When combined with a small number of surveyed ground control points, it is possible to generate topographic surveys accurate to 0.25 feet or better, which is sufficient for many preliminary planning projects. This process also allows for the easy calculation of the volumes of stockpiles and excavations, and the depths of cuts and fills to a construction site over time.
Safety is the primary consideration of OMNNI’s UAV program. The pilot in charge of the UAV program, Jason Weis, holds a Part 107 Remote Pilot Certificate issued by the Federal Aviation Administration (FAA). Only pilots with this certification are permitted to fly UAVs for commercial purposes. All flights are fully insured, and only take place after a thorough system of safety checks has been completed.
