New York State Thruway Drone Survey
Town of Le Roy, Genesee County, NY

Gayron de Bruin Land Surveying and Engineering, PC was tasked to collect Topographic Data and Planimetric features for a 500′ stretch of the New York State Thruway in the town of Le Roy, NY.

At GdB, the safety of our employees is paramount, so in order to complete this task and provide the accuracy required by the client, we opted to use Small Unmanned Aircraft Systems (sUAS) to produce low altitude photogrammetry. GdB Staff worked closely with the New York State Thruway’s Regional Permits and Traffic Divisions to ensure that all safety measures and necessary permitting requirements were satisfied. 

In order to produce high quality survey grade topographic maps, GdB first needed to set Aerial Targets and establish the Horizontal and Vertical location using traditional GPS techniques. This was all done while staying off of the well-traveled highway. Once Aerial Imagery was produced, it was processed together with the Aerial Target GPS locations to produce a digital 3D point cloud for feature extraction. A high-resolution geo-referenced orthomosaic photo was also produced.

Phase I & Phase II
Town of Avon, Livingston County, NY

Gayron de Bruin (GdB) was hired to provide a full topographic and utility survey to assist with the engineering and design of new site improvements. A detailed topographic and utility survey along with drone photography was performed for two separate areas (Phase I and Phase II) within the Avon Central School District Property.

Phase I survey limits encompassed approximately 2,200 linear feet of the Clinton Street bus loop and access road. Phase II survey limits included approximately 2.5 acres surrounding the existing bus garage, parking lot and access roads. Elevations and grade breaks were captured at 50-ft intervals to produce contour mapping at 1-ft intervals. Topographic features including existing structures, roads, driveways, curbs, sidewalks, fences and visible evidence of underground and overhead utilities were located while on site.

Any standalone trees located within the survey limits over 4” in diameter were located and described by size and species. Any vegetated, brushy and wooded areas located within the limits were outlined. Additionally utilities located in the field were compiled and mapped with utility records requested through Avon CSD and the Dig Safely New York Service.

A sUAS (drone) was utilized at the completion of the project to capture site photos for the client. These images were used to create a geo-referenced orthomosaic that was provided, along with the digital images, for their use during the design process.
