What is a Topographic Map?
represent lines of equal elevation above (or below) a reference datum. To visualize what a contour line represents, picture a mountain (or any other topographic feature) and imagine slicing through it with a perfectly flat, horizontal piece of glass. The intersection of the moun...

features. BUILDING A TOPOGRAPHIC MODEL INTRODUCTION Topographic maps show the shapes and features of the Earth's surface. A contour line connects places on the map which have the same elevation. To demonstrate the different elevations shown on a two dimensional...
Teacher's Guide: Kids on Mars
scale of a map can either increase or decrease the level of detail you see. Maps are really models of a place in space. A topographic map uses special lines called "contours" to show how the ground surface changes in elevation from one place to another. In most cases, when ...
Science Junction: Which way is North?
topographic map is a representation of a three-dimensional surface on a flat piece of paper. Contour lines, sometimes called "level lines," join points of equal elevation. The closer together the contour lines appear on a topographic map, the steeper the slope (...
Types of Maps
maps to plan trips and for driving directions. Topographic maps include contour lines to show the shape and elevation of an area. Lines that are close together indicate steep terrain, and lines that are far apart indicate flat terrain. Fact Monster/Information Pl...

include brown or green for land and blue for water. Topographic maps are general reference maps showing coastlines, cities, and rivers that use contour lines to show elevation differences. Such maps are helpful to hikers because they can show elevation changes along a trail. Government agencies like the U.S. Geological Survey (USGS) produce these maps that are often based on satellite data or aerial photography. Satellite maps are produced from data recorded by satellite sensors and transmitted to
