A short example of how to consume Lantmäteriets (Swedish National Land Survey) open geodata from a web map tile service (WMTS) in a mobile application.

To get map data from the wmts you need to get an API key and insert it into the code:

• First you need to create a user account (web page in swedish only) to acquire your API-key.

• You also need to have the toolchains installed for your platform of choice.

You have to update the file MapsActivity.java with your API token:

//TODO: Insert your API key here
private static final String OPPNADATA_URL =
    "https://api.lantmateriet.se/open/topowebb-ccby/v1/wmts/token/<MY OPEN DATA TOKEN>/1.0.0/topowebb/default/3857/%d/%d/%d.png";

Create a new Google Maps Activity Project in Android studio. Make sure you have your Google API key in google_maps_api.xml. Replace the AndroidStudioProjects/MyApplication/app/src/main/java/com/example/MapsActivity.java with the file from this repository. Run your app!

Open the iOS Playground in Xcode and follow along!
