A topographic map, simply put, is a two-dimensional representation of a portion of the three-dimensional surface of the earth. Topography is the shape of the land surface, and topographic maps exist to represent the land surface. Topographic maps are tools used in geologic studies because they show the configuration of the earth’s surface. A topographic map, simply put, is a two-dimensional representation of a portion of the three-dimensional surface of the earth. Topography is the shape of the land surface, and topographic maps exist to represent the land surface. Topographic maps are tools used in geologic studies because they show the configuration of the earth’s surface. Engineering geological maps and plans are used mainly for planning and civil engineering purposes.

The data they gathered along these flight paths enabled the team to determine key characteristics of the rocks, which provided tantalising new clues about how the edge of East Antarctica evolved. This is important because East Antarctica is the least known region of Earth. Unlike your basic road map which focuses on the locations of roads and cities, geologic maps provide information about the rocks that are on or near the earth's surface.
