What does as _ is mean in trace geometric network?
AS_IS —Weight ranges specify features that can be traced. This is the default. NOT —Weight ranges specify features that cannot be traced. The weight to use to create the along-edge weight filter, which is used to filter edge features during the trace.
What should I expect from a network trace widget?
The Network Trace widget is designed to call and interact with any geoprocessing service. The input should be a point feature or features, and the output can return polygon, polyline, or point features as results.
How to find features in a geometric network?
TRACE_UPSTREAM — Find all features that lie upstream (against flow direction) of a given point in your network. Requires flow direction to be set on the geometric network. Point features representing a set of barriers. Barriers define places in the network where traces cannot pass through.
How to select the geometric network in ArcGIS?
There is no option to select the geometric network from a layer drop-down list as input. The geometric network on which the trace will be performed. The name of the group layer that will store the results of the trace as a selected set. Point features representing a set of flags that serve as starting points for the tracing operation.
Where to place barriers in a geometric network?
If you are only interested in tracing a particular part of your network, you can use barriers to isolate that part of the network. Barriers can be placed anywhere along edges or junctions, but junctions will be considered first when both a junction and edge are found at the location.
How does an isolation trace work in ArcGIS?
ISOLATION — An isolation trace discovers features that isolate an area of a network. A table or feature class containing one or more records that represent the starting points of the trace. This feature class or table must include the FEATUREGLOBALID field to store information from the associated network feature.
How is the shortest path on a trace network determined?
Requires a weight to be defined for the trace and flow direction to be set on the geometric network. When a weight is not specified, the shortest path is determined by the least number of features between the two points. FIND_PATH — Find a path between two or more flags in the network.
