Points of equal elevation

- Put simply, contour lines mark points of equal elevation on a map. If you trace the length of a line with your finger, each point you touch is the same height above sea level. If you were to walk the path of a contour line in real life, you would remain at the same elevation the whole hike, never traveling up or down.

The distinctive characteristic of a topographic map is the use of elevation contour lines to show the shape of the Earth's surface. Elevation contours are imaginary lines connecting points having the same elevation on the surface of the land above or below a reference surface, which is usually mean sea level.
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.

Contour Lines
Ever noticed those squiggly lines all over your hiking map? Other than the obvious trails and rivers, these squiggly lines are contour lines. Put simply, contour lines mark points of equal elevation on a map. If you trace the length of a line with your finger, each point you touch is the same height above sea level. If you were to walk the path of a contour line in real life, you would remain at the same elevation the whole hike, never traveling up or down. Contour lines are critical to under...
Topographic Maps
Topography is the study of geographical features on a landscape. A map with contour lines on it is called a topographic map. Topographic maps use a combination of colors, shading and contour lines to represent changes in elevation and terrain shape. Essentially, topographic maps represent the three-dimensional landscape of Earth within the two-dimensional space of a map. Credit: ThingLink The first known maps to include geographical features were found in Ancient Rome. It would be thousands o...
After reading contour lines on a map for a while, you’ll notice that a few distinct shapes pop again and again. Learning to identify common contour line formations will help you read topo maps quickly, and recognize the various terrain features they represent on a map. Let's dig into 'em.
A quick glance at a topographic map will give you a general idea of the landscape. Is it flat or mountainous? If each line represents an equal point of elevation, then any change in elevation would lead to inconsistent line spacing, right? For example, several contour lines spaced close together would indicate steep terrain, while lines spaced far ...
Of course, paper maps aren’t the only topographic tool out there. Smartphone apps and computers can provide any topographic map you may need quickly and accurately, even beyond the reach of wifi and cell signals. Google Maps.You can turn their topographic view (complete with contour lines) by selecting the “Terrain” layer from the options menu. Gai...
How to determine if an off-trail section is too steep from the topo map? Degrees of steepness The closer together the contour lines on your map are, the steeper the slope. Looking at how many feet per mile you are gaining or losing is a good way to estimate how steep a trail will be. Gradual climbs have less than 500ft/mi, moderate have 500-800ft/m...
Topographic maps have contour lines that connect points of identical elevation above sea level. Contour lines run next to each other. Adjacent contour lines are separated by a constant difference in elevation, usually noted on the map.
Aug 10, 2021 · Contour lines are one of the easiest features to identify in a topographic map. They are the solid coloured lines that show elevation changes on a map. A contour line is associated with the difference in height of two points on a map.
A topographic map is a type of map that adds a vertical dimension to an otherwise two-dimensional map defined by the north, south, east, and west compass directions. This third dimension on a topographic map is represented by contour lines , which represent a constant elevations above either sea level (either average sea level (a.s.l.) or mean sea level (m.s.l.)).

Aug 18, 2022 · Topographic Contours. Many maps of land areas have series of curved lines, called contours, that represent the topography of the area. Such a map is called a topographic map. A contour is a horizontal curve that’s the locus of all points on the map with the same elevation (Figure 3-35).
