enhancement - Heatmap overlays

[johndpope]

Are there any plans to extend gl-native to support heatmap overlays?

#2167
#3420

There are different sdks to support mapkit / google maps - but it doesn't look like the native mapbox sdk can currently support this.

Yes, Android SDK 4.2.0 (in beta) and iOS SDK 3.4.0 (in alpha) do support faux heatmaps using circles, but using a clustered GeoJSON source and circle layers rather than the MGLCircle class proposed in #2167.

The Android demo application has a a heatmap activity that demonstrates how to do this. We don’t have an example ready for iOS yet, but the relevant classes are MGLGeoJSONSource and MGLCircleStyleLayer, and you may be able to follow the Android and GL JS examples to some extent.

In case the faux heat map solution I mentioned above (which I’ve since learned is called a “hot spot map”) doesn’t meet your needs, I’ve filed mapbox/DEPRECATED-mapbox-gl#27 for adding support for real heat maps.
