Hi @HimmatSingh
The documentation here describes how to use the acceleration and compass signals.
https://docs.microsoft.com/en-gb/powerapps/maker/canvas-apps/functions/signals
It is not possible to retrieve acceleration and compass values for a particular location (based on longitude and latitude values), because these are not attributes that are fixed for a location. For example, the compass value will depend on the direction in which the user is facing, so this could be anything.
A possible way to retrieve the altitude would be to create a custom connector and to the call the Bing maps elevation connector. The use of a custom connector would require a premium license.
