What have you tried? It's pretty easy with a Map, CloudDB and LocationSensor component. Use the LocationSensor to track the coordinates, upload the coordinates to CloudDB, and display the coordinates on a Map.
Several examples are in the community discussions. There are many ways to share a location with someone to let them track your location.
- Using Cloud DB How to broadcast a GPS location and share the information on a map with others in real time..CloudDB
- share location of multiple users Social Distancing ... a CloudDB / Location Marker Tutorial
- sharing your location using Texting (sms) How to text your Location to a Phone and Display the Location on a Google Map
and lots more. Is this what you wanted to know?
