Answer 1

Once you get the current position you could calculate the distance between those two points and test if it is less than 10 meters.

Answer 2

Latitude, Longitude, Bearing, Cardinal Direction, Distance, and C#

Answer 3

Then use the great-circle distance formula. THough in reality, when looking at such short distances with respect to the planet's radius, a simple 2D euclidean distance between two points is going to be close enough.
