GenerateNodeLinkSchema

Description

Generate a node-link schema. The nodes are defined by the centers of the polygons representing basins and by points that represent locations of interest in the model. The points include basin outlets, river junctions, water intakes and other facilities.

Usage

Parameters

Direction	Type	Parameter Name	Data Type	Dialog Reference
Input	Required	Input Schema Junction Feature Class	GPFeatureLayer	Input Schema Junction feature class (e.g. HydroJunction). May be created using the tool Create Hydro Network from Catchment or Create Hydro Network from Subwatershed.
Input	Required	Input Schema Edge Feature Class	GPFeatureLayer	Input Schema Edge feature class (e.g. HydroEdge). May be created using the tool Create Hydro Network from Catchment or Create Hydro Network from Subwatershed.
Output	Required	Output Schema Link Feature Class	GPFeatureLayer	Output Schema Link feature class. The following fields will be created: HydroID FeatureID: HydroID of the original DrainageLine/Stream feature used as source for the link. FromNodeID: HydroID of the upstream SchemaNode. ToNodeID: HydroID of the downstream SchemaNode. DownElemID: Always HydroID of the downstream Node. LinkType: 1 - Subbasin Link 2 - Routing Reach
Output	Required	Output Schema Node Feature Class	GPFeatureLayer	Output Schema Node feature class. The following fields will be created: HydroID FeatureID: HydroID of the original feature used as source for the node (basin or junction). DownElemID: If the node is of type basin, HydroID of the downstream node. If the node is of type junction, HydroID of the dowstream link. SrcType: 0 - Outlet Node 1 - Subbasin Node 2 - Junction Node HyElemType: 0 - Outlet (SrcType=0) 1 - Subbasin (SrcType=1) 2 - Junction (SrcType=2)
Input	Optional	Input Schema Polygon Feature Class	GPFeatureLayer	>Input Schema Polygon feature class. Optional.
Input	Optional	Input Schema Polygon Centroid Feature Class	GPFeatureLayer	Input Schema Polygon Centroid feature class. Optional. If provided, will be used as source to create the subbasin nodes.
Output	Derived	Ouput Schema Polygon Centroid Feature Class	GPFeatureLayer
