How To Find Elevation On A Topographic Map
It can be either above the sea level or below the sea level.
How to find elevation on a topographic map. Topographic maps are tools used in geologic studies because they show the configuration of the earth s surface. Find the elevation and coordinates of any location on the topographic map. A topographic map simply put is a two dimensional representation of a portion of the three dimensional surface of the earth. On some topo sheets a peak may also include its specific elevation.
Elevation map with the height of any location. Cartographers solve the problem of representing the three dimensional land surface on a flat piece of paper by using contour lines thus horizontal. Find the elevation of your current location or any point on earth. An important feature of topographic maps is the use of contour lines to note elevation.
Think of contour lines as imaginary horizontal planes sliced through the terrain surface. The contours on your topographic map show you where on the landscape elevation changes occur and the contour interval tells you how big a change is represented between contour lines on the map. The elevation maps are generally known as. 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.
Get altitudes by latitude and longitude. A contour line connects points of similar elevation. To use the elevation finder tool. On topographic maps they are indicated by brown lines and come in three types.
A topographic map or an elevation map shows the various elevations in a region. Topography is the shape of the land surface and topographic maps exist to represent the land surface. Zoom and pan the map to find the desired location click on the map to place a marker you will then see the estimated elevation displayed below the map. Elevation of ross oh usa topographic map altitude map this tool allows you to look up elevation data by searching address or clicking on a live google map.
They show the shape of the terrain including its hills slopes and depressions by tracing a constant line of elevation on the map that corresponds with the landscape in the real world. A contour line connects the points in a map representing areas with the same elevation levels. For example a map with a contour index of 20 feet will show elevation changes in 20 foot increments. Index contour lines are labeled with their elevation value and are dark brown.
Contour lines are the primary and most important feature on a topo map. Elevation in a map is shown using contour lines bands of same colors or by numerical values giving the exact elevation details. In general you are not going to find an elevation on a topographic map but rather an estimated elevation by knowing that your location is between two contour lines in feet or meters above sea level that correspond to proximate elevations. The distinctive characteristic of a topographic map is the use of elevation contour lines to show the shape of the earth s surface.
