Final answer:
Absolute mapping is the method that uses a fixed point, such as a coordinate system, to define the exact location of features on the Earth's surface.
Step-by-step explanation:
The mapping method that uses one object as an anchor for all measurement is known as Absolute mapping. This technique involves using fixed points, usually from a coordinate system like latitude and longitude, to define the exact location of features on Earth's surface. It is distinct from Relative mapping, which defines the position of an object in relation to other objects.
