Ya Puedes Pagar tu Predial
The Municipal de Mazatlán in México have used Google Maps to show all the locations where citizens can pay their property tax.
Users of the map can select from a list of the locations that will accept property tax payments and then view the location on a Google Map and in Street View. The full address of each listing is also displayed beside the map.
Citizens of Mazatlán may not like paying their taxes but I think they will appreciate the usability and design of this Google Map.
