Topographic Survey – Ohio State Fairgrounds Play Area – ODNR – Columbus, Ohio
STONE provided topographic survey services for an area located in the southeast corner of the Ohio State Fairgrounds, known as the “Natural Resources Park.” The survey noted readily observable and marked/located utilities, improvements, trees, etc. within the project area. The survey data was processed and a topographic surface created that showed existing features. Topographic mapping was in one-foot contours, and two vertical site benchmarks were set. The deliverable was a base map in AutoCAD format, with survey data on the Ohio State Plane North Coordinate System and the NAVD 88 as established by GPS.
