Find what is inside a polygon

A spatial join joins the attributes of two layers based on the location of the features in the layers. Like joining two tables by matching attribute values in a field, a spatial join appends the attributes of one layer to another.

Use these steps to create a spatially joined dataset based on what is within a polygon:

1. Select a feature polygon layer in the Contents pane.
2. On the Data tab, click Spatial Join .

   By default, Target Features should list the layer to which you want to join data. If it does not, click the drop-down menu and select the layer.

3. Click the Join Features drop-down menu and select the polygon layer.
4. Under Match Options, choose Completely within.
5. Change additional parameters as needed. See Spatial Join for more information.
6. Run the tool.

A new layer is added to the map.
