SEN-025 (PID 119654) – Fostoria, Seneca County, Ohio

The Fostoria Railroad Grade Separation project was aimed at improving accessibility

within the eastern section of the City. The neighborhood is surrounded by railroad tracks

to the north, west, and south with multiple at-grade crossings which intersect with Norfolk

Southern (NS) and CSX rail lines. The goal of the project was to implement significant

roadway improvements to enhance emergency response accessibility, ensure the safety

of the traveling public, and increase mobility and quality of life for residents. DGL’s flight

mission was executed to collect high resolution aerial images of the existing roadway

prior to the design of major improvements.

The produced orthomosaic aerial was utilized as reconnaissance for survey work to be

performed in the neighborhood. To provide our survey team with a more detailed site map

for the ODOT SEN-025 project, a DGL Flight team collected high resolution aerial images

of the roadway, railroad crossing and neighboring right-of-way utilizing the Mavic-3E RTK

sUAS. Once processed, this orthomosaic georeferenced map was used to streamline

project planning and provided assurance that all required planimetrics were observed by

our team on site.

Safety Considerations and Operational Limitations

Avoidance of Flying Over Moving Vehicles: Per FAA Part 107.39 regulations, UAVs

are prohibited from flying directly over moving vehicles unless specific waivers or

conditions are met. To avoid flying directly over the public street, the mission course path

was conducted over the grassy area next to the road.
