What is a Base Layer?
In redistricting, the base layer is the most
detailed geographic layer of the plan; all other layers in the
hierarchy are larger aggregations of the polygons in the base layer.
For example, a city council district plan may use Census blocks as
the base layer or a state congressional district plan may use voting
districts as the base layer.
