Administrative areas are categorized by\nfunction, for example country, state, locality, and postal code. Feature types\nare arranged by administrative level, the structure of which varies by country.\nThese include:\n\n- `GMSFeatureTypeCountry` --- The national political entity, typically the highest order type.\n- `GMSFeatureTypeAdministrativeAreaLevel1` - A first-order civil entity below the country level. Within the United States, these administrative levels are states.\n- `GMSFeatureTypeAdministrativeAreaLevel2` --- A second-order civil entity below the country level. Within the United States, these administrative levels are counties.\n- `GMSFeatureTypeLocality` --- An incorporated city or town political entity.\n- `GMSFeatureTypePostalCode` --- A postal code, as used to address postal mail within the country.\n- `GMSFeatureTypeSchoolDistrict` --- A school district; includes unified, elementary, and secondary.\n\nAdministrative areas are represented on the map as feature layers; each type has\nits own layer. Feature layers are enabled per map style. You can choose which\nfeature layers to enable when setting up your map style in the\nGoogle Cloud console.\n\nStyle boundary polygons\n\nYou can apply styles to boundary polygons for fill (color, opacity), and stroke\n(color, opacity, stroke weight). Use styling to:\n\n- Style a boundary polygon or show all the boundaries for a feature type.\n- Create a choropleth map.\n\n[Google boundaries coverage](/maps/documentation/ios-sdk/dds-boundaries/coverage) shows per-country availability of feature\ntypes."]]
