The Aeris Interactive Maps SDK allows developers to create custom maps from any base map service like Google Maps, Open Street Maps, or Mapbox. Use the SDK to add point data, weather overlays, or animation to your custom map. Note that an Aeris API subscription is required to get started with Interactive Maps.
After continued developer requests, Google has added marker clustering to Google Maps SDK for iOS Utility Library. The feature allows users to populate maps with a large number of markers while keeping the map clean and readable. As zoom levels adjust, markers aggregate and slit out accordingly.
