New basemap styling is coming soon to Google Maps Platform. This update to map styling includes a new default color palette, modernized pins, and improvements to map experiences and usability. All map styles will be automatically updated in March 2025. For more information on availability and how to opt in earlier, see New map style for Google Maps Platform.
Data-driven styling for boundaries lets you access Google's polygons for
administrative boundaries, apply styling to boundary polygons, display them on
your maps.
Data-driven styling for boundaries lets you target regions by place ID, and apply
custom styling to boundary polygons on the map. Each feature type represents a
type of region; you select which feature types to enable when configuring a map
style. Consult Google boundaries coverage to see per-country
boundary coverage.
Feature types
Data-driven styling provides access to Google boundaries for feature types that
represent administrative areas. Administrative areas are categorized by
function, for example country, state, locality, and postal code. Feature types
are arranged by administrative level, the structure of which varies by country.
These include:
GMSFeatureTypeCountry — The national political entity, typically the highest order type.
GMSFeatureTypeAdministrativeAreaLevel1 - A first-order civil entity below the country level. Within the United States, these administrative levels are states.
GMSFeatureTypeAdministrativeAreaLevel2 — A second-order civil entity below the country level. Within the United States, these administrative levels are counties.
GMSFeatureTypeLocality — An incorporated city or town political entity.
GMSFeatureTypePostalCode — A postal code, as used to address postal mail within the country.
GMSFeatureTypeSchoolDistrict — A school district; includes unified, elementary, and secondary.
Administrative areas are represented on the map as feature layers; each type has
its own layer. Feature layers are enabled per map style. You can choose which
feature layers to enable when setting up your map style in the
Google Cloud console.
Style boundary polygons
You can apply styles to boundary polygons for fill (color, opacity), and stroke
(color, opacity, stroke weight). Use styling to:
Style a boundary polygon or show all the boundaries for a feature type.
