What Do Contour Intervals On A Topographic Map Show

Whenever youre in a remote or unfamiliar area a topographic map and compass are a must. Topographic maps use contour lines to show the shape of earths surface.

What Does Topographic Map Show

In order to keep things simple topographic maps show lines for certain elevations only.

What do contour intervals on a topographic map show. What do contour intervals on a topographic map show. The space between contour lines on a topographical map is a contour interval. If the relief is high bigger change you will need a bigger contour interval.

Contour lines show the elevation of the ground. Basically draw or interpolate between the lines. Before the elevation of any point on the map can be determined the user must know the contour interval for the map he is using.

For example were going to use a contour interval of 10 meters. Also there are always some contours on the map that are printed in a bolder. The contour interval is an even space that represents an increase in elevation.

Now that we have points to connect lets draw smooth contour lines for each interval. For example if your map uses a 10 foot contour interval you will see contour lines for every 10 feet 3 meters of elevation lines at 0 10 20 30 40 and so on. Between transition points of ten 30 40 50 etc add markers where to draw lines.

For instance if the map uses a 20 foot interval there are contour lines at zero 20 40 60 80 and 100 feet.

What do contour lines of a topographic map show. How can you show respect for other hunters. Start studying topographic maps.

On most maps every fifth contour line shown as a heavier or darker line is an index line or index contour. Knowing how to calculate the contour interval becomes a useful skill. Topographic maps are often created from aerial photographs and reveal the contours of the land including hills ridges and valleys as well as lakes rivers creeks trails and roads.

The contour interval measurement given in the marginal information is the vertical distance between adjacent contour lines. We call this spacing the contour interval. What is the relationship between the relief of an area and the contour interval on a map of he area.

Topographic maps show the shape of the land. The spacing of contour lines indicate how steep a slope isshaded. So this means that there will be a contour every 10 meters.

A maps legend usually identifies the contour interval on the map but sometimes only part of a map is available. Learn vocabulary terms and more with flashcards games and other study tools. These lines are evenly spaced apart.

Start studying hunters ed. To determine the elevation of a point on the map a.
