Final answer:
The two methods of matching a map to the terrain with great accuracy are using GPS technology and drawing accurate contour lines.
Step-by-step explanation:
There are two methods of matching a map to the terrain with great accuracy. The first method is using GPS (Global Positioning System) technology. GPS allows the mapmaker to record their position and elevation at various points, which can then be used to create a detailed topographic map. The second method is by using contour lines. Contour lines are lines on a map that connect points of equal elevation, and by drawing them accurately, the map can accurately represent the terrain.
