Description

This function returns the current latitude, longitude, and altitude on a device running FileMaker Go; returns the horizontal and vertical accuracy of the values returned; and number of minutes since the values were returned. The location is obtained via GPS, cellular network, or Wi-Fi.

Returns and caches the current location of a device in the format:

Copy

latitude
longitude
altitude (in meters)
horizontal accuracy (+/- accuracy in meters)
vertical accuracy (+/- accuracy in meters)
age of value in minutes (0.2 would represent 0.2 minutes or 12 seconds ago)

You can use the GetValue function to retrieve any of the six carriage return-delimited values above.

LocationValues fetches the location values until the requested accuracy is met or until timeout. If you cancel the process, FileMaker Go returns the most accurate location in the cache (if any). If no location is received, FileMaker Go returns an empty string.

In FileMaker Pro, LocationValues returns an empty string.

Notes

Each returned value, except that last, ends with a carriage return.
To avoid excessive battery consumption and repeat fetches, specify a larger number for accuracy and a smaller number for timeout.
