Data Description

This data represents over 3,600 survey control marks established and maintained by the Arkansas Department of Transportation (ArDOT). ArDOT’s work on this survey control dates back to the 1990’s. This survey control is used primarily by engineers and surveyors of ArDOT to support planning, maintenance, and construction of ArDOT’s transportation infrastructure. Each control station in this dataset has either a precise Latitude/Longitude used for horizontal control or a precise Orthometric Height used for vertical control, or both.

The accompanying datasheets can be viewed by clicking on the datasheet field url which directly links to the pdf export of the datasheet as maintained in the ARDOT GPS Control database referenced below.
