Sheboygan County - Hydro Polyline Open Data

Description:

The waterlines layer is a polyline layer that represents rivers, streams/creeks, and the outlines of waterbodies. It is also used to designate navigability status (navigable, non-navigable, agricultural). 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. While navigable features may have been spatially adjusted, navigability attributes were not changed. 2. After adjusting a feature, a smoothing process was used (Generalize, smooth, .25 foot maximum offset) to create true curves and give the feature a more cartographic look. This adds significantly more vertices to the features.  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 polyline layer does not include flow or other hydrologic items for analysis - this is simply a surface water layer with navigability attribution. 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.
