This polygon dataset contains county boundaries and features (usually shorelines). The county outlines were digitized from 1:100,000 scale mylar USGS quad sheets. Users can draw this layer instead of using the tile boundary (which is also a county line). Users can display shorelines or legal county lines or both by employing the BAY and DISPLAY items. This layer is presented in the WGS84 coordinate system for web display purposes. Downloadable data are provided in native coordinate system or projection.
