​Topographic maps provide a particular kind of information that is widely used by hikers or other outdoors enthusiasts. They are representations of a geographical area that includes natural and human-made elements. What is specific about these maps is that they indicate the elevation and depression of a surface using contour lines, also sometimes represented through colour schemes. Engineering design technology may include involvement with road design, which intersects with topographic maps. Some of the issues that must be taken into consideration at various stages of road design include minimizing environmental impacts, the plots of the vertical profile of the roadway, drainage requirements, and guidelines or codes for geometric design. In short, a detailed and thorough topographic map provides engineers and architects with the information they need to accomplish a successful design.
