Abstract
 NCDOT Highway Milemarker Inventory and Integration with LRS Track: Transportation Author(s): David Johnson The NCDOT GIS Unit was approached by the NCDOT Pavement Management Unit (PMU) to assist in the creation of a statewide highway milemarker inventory. The highway milemarkers presented a prevalent and consistent set of features for use as highway reference points, which could be used to help PMU track pavement deficiencies. The NCDOT GIS Unit soon realized that the milemarkers could be incorporated in the coordinate linear referencing method, already supported in the NCDOT LRS. Following equipment testing and training with the GIS unit, PMU performed all field data collection with mapping grade differential GPS. As data was processed, PMU employed milepoint reference values of highway milemarkers in the LRS to help track pavement condition across some of North Carolina's most vital roadways. This article outlines the GPS method testing, training, data collection, data processing, and finally potential applications of these data within NCDOT.
