reference point
The time required for one complete cycle of a motion that returns to its starting point is called the period of the motion. It is typically denoted by the symbol T and is measured in seconds. The period is the reciprocal of the frequency of the motion.
In physics, a point of view with regard to motion is called a reference frame. It is used to describe the motion of an object relative to a chosen point or object, providing a frame of reference for measuring distances and velocities. Different reference frames may result in different observations of the same motion.
A change of position to a reference point is called displacement. Displacement is a vector quantity that describes the overall change in position of an object relative to its starting point. It includes both distance and direction traveled.
Motion is always relative, depending on the reference point. If a tree is the reference point, then the car zooming past will be moving. But, if you use the car as the reference point, then it seems as though the tree is zooming past.
Period. It is the time it takes for a periodic wave or motion to complete one full cycle, returning to its original position or state.
reference point
For Latitude, the Equator is the zero point. For Longitude, the Prime Meridian at Greenwich UK, is the starting point of zero.
It is called the epicenter which is the starting point.
the prime meridian is the starting point when measuring the longitude

It is used to describe the motion of an object relative to a chosen point or object, providing a frame of reference for measuring distances and velocities. Different reference frames may result in different observations of the same motion.
the equator
The starting point would be the equator. Lines of latitude run parallel to the equator.
It would depend on what you were measuring as to how it would be graphed (distance from starting point vs time, distance to a certain point vs time, horizontal location vs vertical location, etc).
The starting point in a race is called the starting line. The end point of a race is called the finish line.
