The feature is a point shapefile that has eleven subtypes to classify data; bend, cap, coupling, cross, fitting, reducer, sleeve, saddle, tee and wye. A bend is a single pipe joint that can be up to 90 degree angle. A cap is a sealed entrance point to get into the sewer line. A coupling is a flexible connector that has two metal fittings that grasps the pipe with the joint that can be tightened to specification. A cross is a joint with two entrances into the pipe on both sides. A fitting is a standard joint that is straight with no bends. A reducer is a converter that connects a larger pipe size to a smaller pipe size. A sleeve is a protective ring used to keep a pipe hole open and creating a cover barrier between a pipe and its surroundings. A saddle is used for lateral connections, eliminating the need for a T-fitting. A Tee is a perpendicular connection, most widely used in this dataset. A wye connects on a 45 degree angle. |
