Dempsey Surveying

read moreDempsey Surveying utilizes real time GPS receivers to establish accurate horizontal and vertical control for large scale mapping projects. This data related to geography can be tied to the National Spatial Reference System or the Ohio State Plane Coordinate System. We use cell phone technology to communicate with ODOT base stations and by doing so can obtain centimeter accuracy in seconds. Mapping based on this system enhances the efficiency in exchanging mapping information with others. There are many cost saving benefits as well.

The UAV flies autonomously for the entire duration of the flight, collecting imagery in a pattern that is efficient without jeopardizing quality.
