Looking for advanced features to add to your maps? The Maps SDK for iOS Utility Library on GitHub is an open-source library of classes that are useful for a range of applications. The GitHub repository includes the utility classes and a demo app that illustrates the use of each class.
Quick start
Run pod try Google-Maps-iOS-Utils to run the demo app.
For more details, follow the setup guide.
The utilities
Manage marker clusters
The GMUClusterManager helps you manage multiple markers at
different zoom levels. This means you can put a large number of markers
on a map without making the map hard to read. When a user views the map
at a high zoom level, the individual markers show on the map. When the
user zooms out to a lower zoom level, the markers gather together into
clusters, to make viewing the map easier.
Create a quadtree to track points in a given area
A quadtree is a data structure that's useful for finding points near a single point, by searching inside an area surrounding the point of interest.
Render KML and GeoJSON
KML and GeoJSON are popular formats for rendering geographic data such as
points, lines, and polygons. The GMUKMLParser and
GMUGeoJSONParser let you parse and render geographic data in
KML and GeoJSON formats, respectively.
Add heatmaps to your map
Heatmaps make it easy for viewers to understand the distribution and relative intensity of data points on a map. Rather than placing a marker at each location, heatmaps use color and shape to represent the distribution of data.
