Hi Jerry,
I think this question is likely a continuation of your previous post, https://learn.microsoft.com/en-us/answers/questions/2247042/how-to-make-my-azure-map-determine-accurate-locati. Essentially it is not Azure Maps that provides you the co-ordinate but the device. It is up to the user of that device to offer you a less precise or more precise co-ordinate. Work with the Developer APIs for the device that you are using to ensure the user is asked to share the precision co-ordinate and you will likely get better results.
Sincerely,
