I am trying to get shape files for all of the worlds admin levels, but also their localities. If you are familiar with the Google Places API, you will notice that they have Country, Admin level 1, Admin level 2... all the way to 5, and them some other place types that I presume they define.
Cities are considered localities by Google Places, but according to this list, cities could be an Admin level 3.
I have dowloaded the gadm.org shape files split into 6 layers and imported into PostgreSQL/PostGIS, and now I am viewing with QGIS.
The problem is, there are NO United States cities. Why is this? Is there a reliable place I can go to get GIS data for cities? I have checked out census.gov and I see incorporated places data, which seems to include cities, but the borders for Austin (as an example) look different than what Google considers "Austin".
