I need the dialog to get the current gps coordinates for the construction of a "line of orientation", from the starting point to the position of a person - building a WMA. The line should be in motion with the person - the starting point is fixed. The person - a rider - has only one hand free ... and cannot zoom in and out. Without having both the starting point and the position in time on the screen, the rider can follow the direction of the "line of orientation" to find one's way home. The WMA for 2 fixed positions works - I am missing the "line in motion". Any suggestions?
