Digitized center from pipe end to pipe end.
Description: Line used to connect drainage features where culverts were not present to maintain a consistent hydrological network. Digitized from endpoint of drain to endpoint of drain.
Description: Line used to connect linear hydrological features where no culvert is present to maintain a consistent hydrological network. Digitized from endpoint of feature to endpoint of feature. Hydro connector took precedence over drain connector where hydro joins drains.
Description: Concrete on the end of a transverse drain or box culvert. Digitized the centerline of headwalls, such as those on ditches or under driveways.
