Hydrography Lines 2021

This layer contains hydrography such as streams, rivers, and other linear hydrography features. Hidden hydrography, inferred drainage connectors, or culverts connect visible hydrography to form a continuous network. These connectors or hidden features maintain a predictable direction connecting the 2 points that conceal or infer the feature.Streams: Captured as single line if less than two meters wide. Both water edges plotted if wider than two meters.Docks and Piers: Visible outline delineated.Jetty: Visible outline delineated.Seawall: Single line plotted at the face of the seawall.Hidden Hydrography: Hidden hydrography is not obvious, even to someone standing under a bridge for example; it cannot be seen photogrammetrically and can be captured only from other sources. Segments of rivers, streams, and canals that flow under features such as bridges and roads are captured as continuous portions of the river, stream, or canal.
