Given f (x) = 3x + 7, find f (5). Topographic maps show the three-dimensional shape of the landscape by representing equal elevation with lines on a two-dimensional map; they are in essence a type of contour map (also used in meteorology and oceanography). Although these can be mathematically derived, most geologists create them by measuring the elevation (and position) in the field (or on an aerial photo), plotting elevation on a map and connecting lines of equal elevation (much like connect-the-dots except that all the same numbers are connected, rather than in sequence). This module is designed to give you experience examining and reading topographic maps, understanding scale, calculating slope and drawing topographic profiles.
