GPS on Bench Marks
GPS on Bench Marks is the National Geodetic Survey's crowdsourcing approach to obtaining survey-grade GPS data on a prioritized list of marks where new data will provide the most benefit. Surveyors, engineers and technicians that work for Federal and State government agencies, universities, professional societies, and private sector firms use their GPS equipment to take measurements on survey marks in the areas where they work and share them with NGS via our online tools. The public can also participate by finding the survey marks on the priority list and reporting back to NGS on their condition and suitability for GPS observations. This crowd-sourced data helps to improve the local accuracy of national scale models and tools that NGS builds to serve the Nation.
