摘要：	Positional data collection eff orts performed by personnel and contractors of the Louisiana Department of Transportation and Development (DOTD) requires a reliable and consistent measurement framework for ensuring accuracy and precision. Global Navigational Satellite Systems (GNSS) technologies, which include the global positioning system (GPS) maintained by the United States, are used extensively throughout government and industry. The increased accuracy, reduced cost, and improved effi ciencies of these technologies are rapidly being adopted for new and existing workfl ows. For this reason, DOTD requires standards and procedures to guide staff and contractors in the appropriate use of GNSS technology that will ensure application-specifi c data accuracy requirements for mapping-grade devices.
