What is map and geolocation integration?
Map integration embeds an interactive map in your app — letting users see locations, browse nearby results, or drop a pin to enter an address. Geolocation goes alongside it: using the device's GPS or browser location to know where the user is, then doing something useful with that information.
Common providers are Google Maps (the most widely used, with the richest Australian data), Mapbox (more design-flexible and cost-effective at volume), and Apple Maps (available in native iOS apps). All offer APIs for rendering maps, converting addresses to coordinates (geocoding), and converting coordinates back to readable addresses (reverse geocoding).
In an Australian context, map integration often involves suburb and postcode lookups, which require reliable geocoding of Australian addresses — Google's dataset is the strongest here for local addresses. Suburb boundaries (SA2 regions) and postcode polygons are sometimes needed for features like "search within this suburb."
When does your app need it?
- You want to show users their nearest locations — stores, service providers, job sites
- Users need to enter an address and you want a typed search with autocomplete rather than free-text fields
- Your app displays assets, deliveries, or people on a live map
- You're building a field service or logistics tool where location context matters
- You need to let users search by suburb or postcode to filter results
- You're building a property, real estate, or local services product
How much does it cost?
Adding map and geolocation integration typically adds 5–11 hours of development — roughly $1,000–$2,000 AUD.
The simpler end covers embedding a map, displaying markers for a set of locations, and basic geocoding. The higher end involves real-time user location tracking, autocomplete address search, clustering large numbers of markers, custom map styles, and filtering/searching within geographic areas.
Ongoing API costs: Google Maps charges per map load and per geocoding request. For low-traffic apps the cost is negligible; for high-traffic apps, Mapbox is worth evaluating as a cost-effective alternative. Both offer a monthly free tier.
How it's typically built
For web apps, Google Maps is integrated via the @googlemaps/js-api-loader package or the React wrapper; Mapbox uses mapbox-gl or react-map-gl. For React Native, react-native-maps wraps both providers.
Geocoding (address → coordinates) and reverse geocoding (coordinates → address) call the provider's API server-side to keep the API key secure. Address autocomplete uses the Places API to suggest completions as the user types — a significant UX improvement over plain text address fields.
The browser Geolocation API (navigator.geolocation) requests the user's current position. Users must grant permission; the prompt timing and copy affects acceptance rate. For mobile apps, consider foreground vs background location permissions separately.
Questions to ask your developer
- Which map provider are you recommending and why? Google Maps, Mapbox, and Apple Maps each have different strengths, pricing, and Australian data quality.
- What are the estimated ongoing API costs at our expected traffic? Get a rough monthly figure for the usage tier your app will be in.
- Is address autocomplete included? It's a much better UX than asking users to type a full address — confirm whether this is in scope.
- How is the API key secured? Map API keys should be restricted by domain/bundle ID, not left unrestricted.
- How many map markers do we need to support? Displaying thousands of pins requires clustering — confirm this is handled if your dataset is large.
