About this example

This example shows the detailed steps of sharing and using a map and a geoprocessing service. The model TraceGeometricNetwork used in the service is derived from the Trace Geometric Network tool. The geoprocessing task lets you select a point on a water network from which to run a trace. The result of the trace will be a feature layer containing all the values upstream from the start of the trace.

Data

The study area for this example is a water network. Data includes standard aspects of a water network such as mains, laterals, and valves. Also included are roads and parcels for the area of interest. The data can be found in C:\arcgis\ArcTutor\GP Service Examples\TraceGeometricNetwork\ToolData\Montgomery.gdb.

Model and tool data

The toolbox for the geoprocessing service is TraceGeometricNetwork.tbx, and the source map document for the service is TraceGeometricNetwork.mxd. TraceGeometricNetwork.mxd contains several source data layers: a layer for each feature class in the geometric network as well as layers for roads and parcels. Only the layers that participate in the geometric network are used by the TraceGeometricNetwork model.

Open the TraceGeometricNetwork map document from your Catalog window by double-clicking it.

Model overview

To better understand the model, expand the TraceGeometricNetwork.tbx toolbox, right-click the TraceGeometricNetwork model, and click Edit. The TraceGeometricNetwork model is illustrated below. There are two input variables, Flags and Barriers. Each of these variables is a feature set of points that allows you to interactively define features as input to the model.

The input points supplied by the Flags and Barriers variables are snapped to distribution main features using the Snap tool. Flag Locations is used as input for the start of the trace, and Barrier Locations is used to disable features from the trace.

The model performs an upstream trace from the snapped Flag Locations point(s) using the Trace Geometric Network tool and returns the traceResults layer identifying any valves upstream from the input flag point(s). The Select Data tool is used to extract the values, and the Make_Feature_Layer tool is used to create a layer containing just the traced valves.
