New, more efficient methods of measuring road surfaces, including using moving vehicles, are being developed and deployed. Testing the veracity of such data presents its own problems. Busy, heavily traveled highways do not lend themselves to easy occupation for careful measurements by conventional means. The advent of GULFNet by the Louisiana State...

... Horizontal and vertical measurements have been collected using survey-grade GNSS techniques at locations designated by the PMS Section. The locations are essentially the same locations surveyed and reported in Project 09-2GT (Cavell & Dokka, 2009 The outcome from this objective will allow the PMS Section to use these control surveys and speed observations to assess the MVRM data for quality and accuracy. ...
... A test area includes a segment of road typically a mile in length. The nine areas were selected by the DOTD, and represent the same locations identified in LTRC Report 09-2GT (Cavell & Dokka, 2009). Table 2 lists the survey locations and districts. ...

The Center for GeoInformatics (C4G) at Louisiana State University (LSU) has conducted a three-part study addressing accurate, precise, and consistent positional control for the Louisiana Department of Transportation and Development (DOTD). 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) was summarized in order to support consistent and accurate access to the National Spatial Reference System. Third, the C4G provided quality control information to the Pavement Management System section against which Moving Vehicle Rapid Mapping (MVRM) data may be compared and assessed.
