Ultra-generalized postal area polygons (Postal_Polygons_Gen)
This ultra-generalized layer provides further simplification of the original generalized (Postal_Polygons_Gen) layer. Postal_Polygons_Ultragen reduces the number of island-like areas that have the same ZIP code by generalizing them into large polygons that can extend over water polygons. The layer's lower level of detail offers an alternative for use cases where a lighter size and a reduced number of vertices is the priority over exact representation of the edges of the ZIP code coverage area.
Note
Postal_Polygons_Ultragen
doesn't replacePostal_Polygons_Gen`; both layers are available in the product.
