City of Wayne GPS Survey

Wayne, Nebraska

The City of Wayne selected Eisenbraun & Associates to assist them in establishing a city-wide mapping system that would be used as the foundation of a future GIS for Wayne.

The E/A Approach
The project was set forth in phases, with the first phase being the development of a survey control network that encompassed the City and a buffer zone around its perimeter. The 19 permanent control points were located and constructed in a cooperative effort with City Staff. E/A survey crews then utilized static GPS survey methodologies to determine precise first-order State Plane Coordinates (NAD 83) on all control points. Our crews also established NAVD 88 elevations on all points by running differential level circuits throughout the project area using electronic digital levels. Once the control network was in place, additional research and recovery of sectional corners was conducted. This was followed by a kinematic GPS survey to determine the state plane coordinates of all the section and quarter-section corners that were found in the project area.

Phase 2 included the targeting of control, obtaining current aerial photography of the project area, and select digital mapping of certain features within the City. The control survey work completed by E/A in conjunction with select digital mapping and digital orthophotography of the city formed the base map of the City of Wayne. The map was then used in the implementation of a geographic information system. Topographic mapping of the South Logan Creek floodplain was included in this phase. E/A CADD technicians also incorporated all of the platted property within the City into the base map.

Phase 3 of the multi-year project involved the survey and mapping of all the City-owned utilities. Included were the sanitary sewer system, water system, electrical system, storm drainage system, and street network. Extensive data collection was completed throughout the community using real-time kinematic GPS techniques to locate all valves, hydrants, curb stops, manholes, transformers, and numerous other elements of the utility systems. Months were then spent to gather, catalog, analyze and input the data attributes relevant to each of those elements.

The Outcome
A functional GIS for the City of Wayne has found great acceptance and usefulness in all the City Departments, and continues to grow and evolve yet today.
