You would just need to generate the following URL: https://www.google.com/maps/@lat,long,zoom where:
* lat is your latitude (e.g. 52.2129919)
* long is your longitude (e.g. 5.2793703)
* zoom is the zoom factor, suffixed with a z (e.g. 12z)
Complete URL: https://www.google.com/maps/@52.2129919,5.2793703,12z
Alternatively, if you want to direct the user from the PDF document to your own app, you can use the deep link module from the AppStore.
