Topographic map of Hawaii: Elevation



Topographic maps typically show the phsyical characteristics of land in an area and the built changes in the landscape. These types of maps are usualy characterized by large-scale detail and quantitative representation of relief. This is acomplished from the use of contour lines in modern mapping as well as shading techniques seen in the map above. This map shows a topographic view of Hawaii's "Big Island". The map shows a depiction of the natural terrain and the elvation changes. It does so by providing a color scale of elevations which corelate to the changes of the islands elevation. This map is also showing the properties of a hypsometric map, where three dimensional information is communicated. In this case the third dimension is represented by both reliefs and color shading to show elevation. Their is also a scale to estimate distance and a legend to denote marking on the map itself.
