These values are summated if multiple operations led to the creation of the dirty area. For example, a deleted feature is represented by bit 1 and is displayed with a status of 2 (2^1 = 2). The Status attribute field uses bitwise encoding to represent the operation that created the dirty area. The dirty areas sublayer is symbolized using the Status field to indicate how it was created: Upon the creation of an error, a dirty area is created that encompasses the feature's geometry. Dirty areas are used to represent errors that are generated by the system when a feature in the utility network is in violation of established rules and restrictions. With Utility Network version 4 and later, dirty areas are also used to identify and work with errors discovered for network features. For example, editor tracking fields can help to display dirty areas in which a certain editor performed work, or when the edit occurred. You can symbolize the dirty areas based on attributes in the dirty areas layer. The dirty areas are still created, but you will not see them on the map. For example, if you are making edits to your network and you find the dirty areas are visually distracting, you can turn off the layer. The visualization of dirty areas can be turned on and off like any other layer.

Fields that are defined as network attributesДirty areas are created when errors are discovered during the following processes:Дirty areas can be accessed as a sublayer of the utility network and can be symbolized using core symbology tools.

Modifications to the following create dirty areas:

One represents the envelope of the feature's previous geometry, and the other represents the feature's new geometry. If a feature's geometry is modified, two dirty areas are generated for the single feature. When the network topology is enabled again, all outstanding edits are validated.Дirty areas track the extent of the feature that is edited, the type of edit, the global ID of the feature, and Dirty areas also remain for any features with errors. When a network topology is disabled, a single dirty area covering the network is created. Edits that are not reflected in the network topology are not considered with network analytic operations, such as tracing or network diagrams.

Validate is used to update the network topology and clear dirty areas. The dirty area signifies that a change was made to the utility network but has not been updated in the network topology. This can include creation of features, modifying fields associated with network attributes, establishing or modifying associations, and so on. When the network topology is enabled, dirty areas are created to track edits. Dirty areas are cleared when the network topology is validated, as long as no error exists within the validation extent. They serve as an indicator that a change to the network has taken place that is not reflected in the network topology.

Continue fixing topology errors as needed.Dirty areas are created to flag the location of edits made to the geometry of network features and network attributes, or to display errors.

Areas that are not currently visible on the map are not validated.

Click Validate Topology In Current Extent.

The features that fall within the bounding box will be validated.

Click Validate Topology In Specified Area and drag a box around the area you want to validate.

You can validate a portion of a topology using the tools on the Topology toolbar.

This occurs because the vertices on each polygon must be at the same coordinate location on each feature when editing shared geometry in a geodatabase topology. For example, you might notice that ArcGIS inserts vertices on adjoining polygons.

In addition to checking for topology errors, validating a geodatabase topology involves a series of spatial processing tasks to identify shared features and maintain coincidence between adjacent features.
