Sheboygan County - Hydro Polygon Open Data

Description:

The waterbody layer is a polygon layer that represents lakes, ponds, and other bodies of water. This layer was updated County-wide in 2023/2024 using the 2022 aerial imagery, 2019 DEM, and State of WI wetlands. The update process involved manual digitizing or adjustment of linework and subsequent polygons. Most linework was adjusted and smoothed (to create true curves), and the polygon created or adjusted using the trace tool so it followed the linework exactly. While no set standards were used in this update, several general protocols were followed: 1. If an existing polygon was present in the State of WI wetlands layer and was not an obvious pond, it was marked as wetland. 2. Wet areas or small bodies of water in wooded areas or fields and not in the State of WI wetlands layer were marked as other (neither pond nor wetland). 3. If a large area of wetlands had existing polygons, the polygons were changed to wetlands but may not have been adjusted to the imagery. 4. Named water bodies (according to GNIS) or water bodies with navigable waterways were marked lakes, otherwise they were marked ponds or other. 5. Very small wet areas or bodies of water may not have been mapped.While efforts were made to make this a comprehensive surface water update, some features may not be precise, missing, or inaccurate. Future updates may address these items. This dataset was automatically cataloged from the creator's Open Data Portal. In some cases, publication year and bounding coordinates shown here may be incorrect. Additional download formats may be available on the author's website.
