Abstract:The Center for GeoInformatics at Louisiana State University conducted a three-part study addressing accurate,
precise, and consistent positional control for the Louisiana Department of Transportation and Development.
First, this study focused on Departmental standards of practice when utilizing Global Navigational Satellite
Systems technology for mapping-grade applications. Second, the recent enhancements to the nationwide
horizontal and vertical spatial reference framework (i.e., datums) is summarized in order to support consistent
and accurate access to the National Spatial Reference System. Third, the Center provides quality control
information to the Pavement Management System section against which Moving Vehicle Rapid Mapping data
may be compared and assessed.
