In campusM/Library Mobile, we can add maps to the app by providing the GPS coordinates of the top-left and bottom-right corners. When end-users open one of these maps, it is launched in the device's native mapping application: Google Maps on Android, and Apple Maps or Google Maps on iOS.

We have been using this feature since the beginning; however, it has recently come into conflict with our institutional policy. Our university follows a strong open-science and open-infrastructure policy. We are therefore encouraged (if not expected) to use open solutions and integrations whenever possible. In this context, we are specifically asked to rely on OpenStreetMap rather than Google Maps or Apple Maps across all institutional websites, tools, and applications.

There is also a privacy dimension to this issue. A number of our users access the app content through a web browser rather than the native app and may not expect that using the map feature will automatically redirect them to Google Maps. This is problematic for both transparency and compliance with internal privacy guidelines, as we cannot assume that users consent to sharing location-related information with third-party proprietary services by default.

Given these requirements, we would like to have the possibility to configure campusM/Library Mobile so that maps open in OpenStreetMap instead of Google Maps or Apple Maps.
