Geolocation, Maps

abap2UI5 includes a custom control for retrieving geolocation data from the user's device, such as longitude, latitude, altitude, and speed. This is useful for logistics apps, field service tools, or any scenario where location matters.

The control fires a finished event once the browser has determined the device position. All values are exchanged via two-way binding. See also Z2UI5_CL_DEMO_APP_120.

Browser Permissions

Geolocation requires the user to grant permission in the browser. Make sure your HTTP service uses HTTPS, as most browsers block geolocation on insecure origins.
