| License | The survey data to which the bounding polygons refer are not to be used for detailed engineering or planning purposes, navigation or hazard identification. The survey data has been collected using a variety of methods and over a long historical period. The accuracy of the data is therefore variable and DoT does not provide any warranty as to the accuracy of the Information nor as to its reliability. |
