Filtering your features allows you to work with and focus on a subset of records. By limiting the visibility of features in a layer, you can reveal what's important to you. The following are supported data formats:
Create a filter
A filter uses one or more expressions to determine which features are shown on the map. Each expression includes a field name, an operator, and a value. As you set up the filter, features that do not match the filter criteria will be hidden on the map.
To create an expression for layer filter, complete the following steps:
- Right-click a supported layer in the table of contents and click Filter.
- In the Filter panel, click Add expression to add your first filter expression.
- Click the field selector, and choose a field to use for the expression.
- Click the operator selector and select an operator, such as is, is not, includes, excludes, or contains.
If you select a numeric or date field, a histogram of the data distribution will be displayed to help you choose the data intuitively. You can also set the data filter range by dragging the maximum and minimum values into the histogram.
- In the value text box, enter or choose a value to use in the expression. The text box varies depending on the field type and the operator. For example, if you select the includes or excludes operator, you choose from a list of data values in the specified field. And for the blank operator, no value needs to be entered.
注：
- If the data contains a configured original filter, the expression will display in the panel. The original expression supports deletion and restoration and cannot be edited.
- Expressions will not be saved once ArcGIS Earth is closed.
If the filter has more than one expression, you must choose a matching option to connect the expressions.
- Match all expressions—Only show the features that match all of the filter expressions.
- Match at least one expression—Features will show on the map if one of the expressions is matched.
