OpenMapTiles is a powerful mobile application developed by Klokan Technologies GmbH that puts maps under your control. With this app, you can get the source code and detailed OpenStreetMap vector tiles saved in MBTiles format, allowing you to use them offline and access your GPS location.

One of the standout features of OpenMapTiles is the ability to download street maps for the entire planet, a specific country, or any city of your choice. This offline map functionality is incredibly useful for travelers or those without a reliable internet connection. Additionally, you have the option to embed and distribute the map data along with your own app.

The open-source Mapbox SDK allows you to customize and add your own business logic and extra mapping functionality to the app. This flexibility is perfect for developers who want to create their own independent maps for any location on the planet. OpenMapTiles also offers support, consulting, and contracted development for mobile applications, making it a comprehensive solution for geodata processing and map tile creation.

For those looking for more advanced editing functionality, drawing features, attaching photos, and collecting field data, the GeoEditor mobile app is also available, including its source code.

Overall, OpenMapTiles is a versatile tool that empowers developers to create customized maps and provides users with offline map functionality and GPS location tracking.
