What Are Contour Lines How To Read A Topographical Map 101 Contour lines show stream direction with the v shaped lines through which you see the streams and rivers run through on a topo map. because water flows downhill, the v shape always points in the opposite direction that the water is flowing. this is called the “rule of v’s”. contour lines vs. relief. 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 lines: every fifth contour line is a thicker, "index" line. at some point along that line, its exact elevation is listed. contour interval: the change in elevation from one contour line to the next is.
Topographic Map Contour Lines Howstuffworks Your guide to outdoor adventures and wildlife wisdom. practical tips for gear, wildlife encounters, and essential know how. explore nature with expert advice and fascinating insights. learn how to read a topo map with this comprehensive guide. understand contour lines, scale, legend symbols, terrain features, elevation, and navigation techniques. For each topo map, the elevation gain or loss from one contour line to next is always the same. the contour intervals will vary depending on the map. for most maps it is 40 feet, but you will also find them at 50, 80, or 100 feet. for example, on a map with a contour interval of 40, every contour line is 40 vertical feet from the contour lines. A topographic map is a detailed representation of the earth’s surface, showing elevation changes, contours, and features such as rivers, roads, and vegetation. it provides valuable information for navigation, land planning, engineering, outdoor recreation, and environmental analysis [1]. to read a simple topographic map, you need to know what. This is because when contours are close together, it means that the slope is steeper. for a quick definition, a contour line joins points of equal and constant values. for example, contours on an elevation have constant heights that are the same on each line in a topographic map.

Printed maps will tell you the interval on the map key. in this case, it's 80 feet, so every fainter line is 80 feet higher or lower than the one next to it. most topographic maps have an index line for every 5th line. if you have a printed map, look for the contour interval listed on the bottom. 4: reading the spaces. even the empty space on a topographical map is crucial information. primarily, the space between contour lines is important. while the normal contour lines show what that section of an elevated land feature is like in terms of terrain, they don’t show what the slope is like between elevations.
