Geolocation, Maps

abap2UI5 offers a custom control for reading geolocation data from the user's device — longitude, latitude, altitude, and speed. This is handy for logistics apps, field service tools, or any scenario where location matters.

The control fires a finished event once the browser resolves the device position. Two-way binding sends all values. See also Z2UI5_CL_DEMO_APP_120.

Browser Permissions

Geolocation needs the user to grant permission in the browser. Serve your HTTP endpoint over HTTPS, since most browsers block geolocation on non-secure origins.
