Knowing how to read a topographic map is the foundation of any backcountry adventure. Through the use of contour lines, topo maps bring a 3-dimensional element to a 2-dimensional paper map. Topo maps allow you to visualize the rise and fall of the land and “see” the depths of canyons...
Note the contour lines on the map. These lines connect points of equal elevation. Some lines will have the recorded elevation written in the line. The map's legend will indicate the elevation distances between the contour lines. For example, if the elevation distance is 100 feet, then the c...
Contour lines also indicate the shape of the terrain.Roughly concentric circles are probably showing you a peak, and areas between peaks are passes. Studying a topo map of a familiar area is a great way to learn how to match terrain features with the contour lines on a map. Index contour ...
Topographic Map Basics We begin our focus on the basic part of a topographic map, all those lines. These are known as contour lines. Contour lines connect points of equal elevation. All that means is that where there's a line, everything on that line is the same height or altitude. ...

Different maps use different intervals, depending on the topography. If, for example, the general terrain is quite elevated, the map might run at 80- to even 100-foot (24- to 30-meter) intervals. This makes it easier to read the map — too many contour lines would be difficult to ...
How To Make a Contour MapThe resource shows the dynamic representation of the construction of a contour map that describes a surfaceLouis A. Talman
Understanding map symbols At first glance, it can be overwhelming trying to work out what the various lines and symbols mean, as there is an awful lot of information to take in and you might wonder if you’ll ever learn how to read a map. However, take a breath, consult the legend (...
Today we’re going to discuss how to read terrain off of a map. Reading terrain is more about artistic visualization than it is science. There are three major factors that aid in the visualization of terrain from a 2d map: Contour Lines ...
