Filtering by boundary

You can filter the data items that are displayed in the Operations view according to boundary by using the Where pane. On the map, you can draw boundary areas within data sources that are defined as boundary areas. Alternatively, you can define boundaries by using the data source's data items.

About this task

You can create many boundaries by using boundary area type data sources that supply data as polygons, or multipolygons. For example, your administrator can create data sources that acquire data items in polygon format from either a DB2® or SQL database, a CSV file, or a shape file. For more information about using SQL to define boundary areas, see the related link.

In a data source's configuration, your administrator can configure a filter pane to be automatically generated that displays individual boundary items from the data source. The generated filter pane has the same name as the boundary data source. You can select one or more individual boundary items on the generated filter pane and display the items either on the map or in the list.

Your administrator can set a limit on the number of boundary areas that are displayed in the Boundary area list. If the number of boundary areas exceeds this limit, select View all boundary areas from the list to display entries for all the boundary areas.

In the Where pane, choose from the following options:

• To set the boundary to the current zoom level and pan location that is set on the map, click Area within visible map.
• To set the boundary to an area that you draw on the map, click Drawn area, and then select a shape to draw the area with. After you draw a shape, you can select it, and either edit it, or clear it.
• To set the boundary to a boundary area that is included on the Where pane, do the following steps:
  1. Click Area within selected boundaries. On the map, each boundary area that you selected in your previous session is outlined.
  2. Select a data source from the Boundary area type list.
  3. Select one or more boundary areas from the Boundary area list.
     Note:

     • The Boundary area list displays only the boundary areas that you selected in your previous session. If this is your first session, the Boundary area list displays entries for all boundary areas. Your administrator can set a limit on the number of boundary areas that are displayed in the list.
     • To display entries for all boundary areas in the Boundary area list, select View all boundary areas from the list, and then redisplay the list.
  The boundary areas that you select are displayed on the map or in the list. On the map, each boundary area is outlined.
