Filter

The Filter tool is available for specific layers. A filter can be applied to individual layers (with the exception of cached map services published from ArcGIS Online) in order to limit the features displayed on the map to those that meet the filter definition/criteria. More specific details on how to develop queries that define filter criteria (e.g., querying numbers, combining expressions, using nulls), are provided in the Build a Query topic.

• Create Filter
• Modify or Remove Filter
• NOTE: The Filter option is not available for cached map services published from ArcGIS Online because such services do not support all of the capabilities of those published through ArcGIS Server.

Create a Filter

• Within the Layers tab of the Map, click the dropdown icon to the right of the service to be filtered and choose Filter from the available options.
• NOTE: The Filter option is not available with cached map services, only dynamic services.
  
• If the Resource contains multiple layers, a dropdown identifying the layers will be displayed. Select the layer to be filtered from the Layer dropdown list.
• NOTE: If the Resource contains only a single layer, the Layer dropdown will not be displayed.
• 

• Select the attribute to use in the query from the Attribute dropdown, and then click Select.
  
• Click an operator (=, <>,..)
• To see a list of values for the attribute, click Get Unique Values . Double-click one of the values or alternatively, type an expression directly into the query field.
  
• NOTE: If Get Unique Values returns no records for lack of data in the attribute, a message will be displayed to indicate that No unique values were found for this attribute.
  
  
• NOTE: If Get Unique Values is used on a layer with many records, the following message is likely to be displayed. Respond Yes to continue or No to cancel the search for unique values.
• 

• Click Apply to apply the filter and keep the Filter dialog open or click OK to apply the filter and close the Filter dialog.
• NOTE: If there is a typographical error, or the filter has been improperly defined (i.e., ‘Vascular plant’ instead of ‘Vascular Plant’), no records will be displayed.
• The number of records resulting from the Filter will be reported.
  
• Within the Map Resources dialog, (Filtered) will be displayed next to the service name to indicate that the service has been filtered.
