Intersect

Description of the tool

This tool allows you to select features that overlap features in a different layer.

How to use the tool

Prerequisite:

A feature has been selected from the map.

Steps:

1. Set the Active Layer and select one or many features (using any of the Selection Tools or by using the Search Panel). The features selected are those that will be used in the intersection. 
   
   
   
   
2. Set the Active Layer to the layer from which you would like to select features.
   
   
   
   
   
3. Click on the Intersect tool. 
   
   
   
4. This will display the Intersect the Selected Features menu. Select the layer that has the selected features you wish to use in the intersection operation. 
   
   
   
   Only layers that have features selected will be listed in the Layer list. 
   
   
5. There are four options for Intersection generation:
   • New - This will create a new selection, and will replace any previous selections you had for the Active Layer. 
   • Add - This will add the selected features to the existing selection set for the Active Layer.
   • Remove - The features that result from the Intersect operation will be removed from the selection set for the Active Layer. 
   • Refine - All but the selected features will be removed from the selection set for the Active Layer.
     
     
6. When you press the New or Add button, a red polygon will be drawn around the selected feature on the map outlining the extent of the features used in the Intersection. Features from the Active Layer that overlap the selected features in the Layer specified will be selected.
