Based on Metal for iOS and OpenGL ES for Android and focused on mobile first, WhirlyGlobe-Maply is used in a wide variety of altas, weather, visualization, and map apps. The SDK is both a 3D interactive globe for iOS and a 2D flat (or slippy) map for iOS and Android. It’s all open source. The feature list is pretty long, but here are a few things you can display with the toolkit.
It’s big, but it’s also friendly. You develop with the native tools on each platform and we’ve got some nice tutorials. Developers of all skill levels have made WhirlyGlobe-Maply apps. You can too!
Both iOS and Android versions are mature, with apps deployed to millions of users.
