    • Abstract:
      Global Navigational Satellite Systems (GNSS), which includes GPS technologies

      maintained by the United States, are used extensively throughout government

      and industry. These technologies continue to revolutionize positional data

      collection activities. Despite the increased accuracy, reduced cost, and improved

      data acquisition effi ciencies, the Louisiana Department of Transportation and

      Development (DOTD) has no established standards or methods to guide its

      general staff and contractors in the appropriate use of GNSS technology to

      ensure application-specifi c data accuracy requirements and that a Department

      minimum are met. Because the DOTD Surveying Section already collects highly

      accurate and precise data, these standards are not intended for them. Instead,

      these standards are intended for staff that collect GPS data from mapping-grade

      applications. There is a need to develop standards and techniques for staff

      who collect GPS Data, separate from the survey section, to ensure a minimum

      standard and level of accuracy, not only for a confi dence level in the data, but also

      to ensure compatible software and equipment support and training.
