Abstract
Point features used to enforce connectivity rules between HydroFlowLine subtypes in the Geometric Network.

Purpose
HydroJunction was created from the Node layer of production coverage 7, PRODR7.  The production coverage utilizes fields that help maintain topological integrity between Arcs and Nodes.  These fields indicate frequency of flow to and from nodes as well as the coverage# identification of the Arc feature flowing to that point.  HydroJunction replicates these same principles of connectivity rules by monitoring what HydroFlowline subtype flows in and out of the HydroJuntion.  Through connectivity rules relationships such as HydroFlowLine subtype FlowInWater may not connect to FlowOverLand unless it is through a HydroJunction subtype Shoreline can be established. HydroJunction may also be used to represent intersections in the network that may carry more significance such as the intersection of two streams or the inlet and outlet of a lake through the use of its subypes.  
HydroJunction is created having M and Z values.  In order to participate in the Geometric Network with is composed of HydroFlowLine containing M and Z values, the HydroJunction feature class must also have M and Z values.coverage format.
