I really want this question to be short, so .. I would like to know if Google Maps has detailed information, in this case I need a polygon (array of coordinates) for a specific Municipality inside the city (i.e. Envigado in the city of Medellin, Co)
Is there a way to get this type of data?
EDIT: I'm not sure if Google Maps displays the type of geograph of the polygon I need, as indicated in the answer, maybe not, but a simple query shows something interesting:
