(right-click on a layer with different symbols, go to the Selection manager menu item and select by any symbol value)

 

 

Managing selections

 

The tool is available from the toolbar, no matter if there is a map open or any data currently added in ArcMap:

 

 

Pressing the tool icon opens the Selection Manager dialog window:

 

 

The tool dialog window consists of two main parts:

• Map layers

- Shows all layers in the current map. This part can be collapsed and you can work directly with the TOC window.

• Saved selections

- Shows all selections you created and saved with map document.

 

In the Map layers list you can see all layers added in the current map:

- Layers with selections are marked with bold and number of selected features is given for each layer.

- Invisible layers are marked with strikethrough.

 

Besides, Selection Manager can also be accessed from the layer's context menu:

 

 

From the layer's context menu you can:

- Open Selection Manager dialog

- Create new selection

- Create selection by attribute

- Select features by symbol

- Add selection to any saved selection

- Remove selection from any saved selection

 

Creating new selections

 

Selections may consist of selected features in one or a few layers. In order to create a new selection simply drag one or a few layers from the Map layers list or directly from the Table of contents and drop it to the Stored selections window. By default selections are named Selection 1, Selection 2 etc. but they can be renamed as needed reflecting actual selection content or purpose.

 

Operations with selections

 

Working with saved selections you can union, subtract or intersect selections - as a result, a new selection will be created. For that drag one selection and drop it onto another selection. At that you will be suggested to select an action:

 

 

• Union

- the two selections will be combined into new one

• Intersect

- the new selection will contain only those selections existing in both selections

• Subtract

- the new selection will contain only selections remaining from subtracting one selection from another

 

Example:

 

All operations are made with the selected feature IDs:

Selection 1 contains features: 1, 2, 3, 4, 5, 6

Selection 2 contains features: 4, 5, 6, 7, 8, 9

 

Unioned selection will contain all features: 1, 2, 3, 4, 5, 6, 7, 8, 9

Intersected selection will contain features existing in both selections: 4, 5, 6

Subtracted selection will contain only features unique in Selection 1: 1, 2, 3

 

Intersecting or subtracting selections in different layers will return an empty selection.
