What Are Geologic Maps and Why Are They Important? A geologic map uses lines, symbols, and colors to illustrate information about the nature and distribution of rock units within an area (Figure 16.1).Typically, a geologic map will depict mappable rock or sediment units. A mappable unit of rock or sediment is one that a geologist can consistently …

— Aerial photography, ground photography, plate survey, and other methods are used to map topographic maps and other mining maps on a scale of 1:1,000 to 1:500. The coordinates in surface and underground of mines must be unified, and the earth-fixed axis system is transferred to the underground by orientation and induction height.
— Contour mapping is a technique used in cartography and geography to represent the three-dimensional shape and elevation of the Earth's surface on a two-dimensional map. Contour maps display lines called "contour lines" that connect points of equal elevation above a reference datum, typically mean sea level. These lines help …
