Topography Invitation Suite
Topography is the study of the shape and features of a surface. The term originated in ancient Greece as the detailed description of a place, including local history and culture. In modern times, topography is the recording of three-dimensional surfaces and landforms, using contour lines, hypsometric tints, and relief shading to designate elevation. Early topographic surveys were prepared by the military to assist in planning for battle, so elevation information was of vital importance. As they evolved, topographic maps became an invaluable resource to modern nations, useful for planning infrastructure and resource extraction. The topographic map of Swans Island, Maine used in this suite was created from United States Geological Survey data from 1901.
