How Can I Use My Own Layer to Select Features While Redistricting?

Maptitude for Redistricting uses hierarchies to describe the relationship between nested layers for reporting.

You can use any area (polygon) layer as a selection layer in your plan. Simply choose the layer from the Selection drop-down in the Redistricting Toolbox. **Note: If the area layer was added after the plan was opened, close the Redistricting Toolbox using the x in the toolbox, and reopen it by choosing Redistricting>Redistricting Toolbox”
