General Information

GPS or Global Positioning System refers to technology that utilizes satellites to determine the location of points on the earth's surface. In 2001, our department purchased a Trimble GPS unit that not only measures latitude and longitude, but also calculates the elevation with sub-centimeter accuracy. This is an extremely accurate and useful tool for many applications within our department. Large topographic surveys can now be completed in a single day. Completing such surveys with conventional surveying equipment may have taken a week.

Use of GPS Unit

Since purchasing the Trimble GPS unit in 2001, our department has used it to complete several large surveys and projects. Listed below are several examples of what has been accomplished with this technology:

  • Survey of Terrell's Island Vegetation.
  • Bathymetric Survey on Rush Lake.
  • Survey of Lone Willow Island Marsh breakwall.
  • Shoreline and Streambank Erosion Survey in Pool Lakes.
  • Culvert Surveys in Neenah, Clayton, and Black Wolf Townships.
