Cartographer - the first GeoJSON editor on the Mac App Store Posted 11/04/2014 at 14:26 UTC in Mac by gnye@amdesign.net | Permalink | Tweet UK based False Victories announces Cartographer 1.0, their new maps app for OS X. Cartographer allows developers to quickly add annotations to maps without the need to enter coordinates by hand. The app has been designed to work with Apple's MapKit framework on both OS X and iOS. The Cartographer file format supports all the features of Cartographer and developers can use the freely available CocoaPod - CartographerKit - to integrate it into their own applications.
