Highest and Lowest point on a topographical map can be distin guished by checking out the spot heightsThey r the heights of specific places in the map from above the sea level printed in black inkThese heights will be marked in a regular map at different pointsYou should study the map carefully to find those. A contour line is level with respect to the earths surface just like the top of a building foundation. Determine the contour interval of the map from the marginal information.

Learn how to determine the highest possible elevation of a given point on a topographic map. Count the number of contour. Where they stop would decrease down the other side then you will find a boundary of watersheds of one stream from another.

Every fifth contour line is a thicker index lineAt some point along that line its exact elevation is listed. When reading a topographic map you need to visualize in your minds eye a 3. The elevation and depth are then the difference in height from sea level.

Rather I was taught to read maps by UTM or Universe Trans-Mercator or gridlines which appear on topographic maps. As a hiker this form of numbers being latitude longitude has never held any interest for me as this isnt the format of numbers favoured for wilderness map reading. 2 Contour lines can never cross one another.

Each contour line on a topographic map represents a ground elevation or vertical distance above a reference point such as sea level. As you look at the map notice that the contour lines enclose smaller and smaller areas. To calculate elevation you need to have a reference point of a known elevation.

You will then see the estimated elevation displayed below the map. Horizontal distance is found on the scale. The only exception to this rule is if.

You can find a topographical map of your property by searching online.

Locate the point on the map. A brief introduction to determining the exact or estimated elevation of a location on a topographic map. Index contour lines are labeled with their elevation value and are dark brown.

To use the elevation finder tool. It may already be plotted on the map or given as eight-digit coordinates. Also called elevation maps these color-coded maps show elevation and contours of your property.

A Topographic Map includes contour lines drawn to represent changes in elevation. 4300 4200 100 and 100 5 20 so each contour on this map is 20 feet. A contour line connects points of similar elevation.

Edge of the map but if you got the adjacent map you would find that eventually the contour will close on itself. An important feature of topographic maps is the use of contour lines to note elevation. The change in elevation from one contour line to the next is always the same within the same mapMany maps have either a 40- or 80-foot contour interval.

See the map below showing this example. Click again to place further markers and find the elevation. When you follow a path on a topographic map that crosses these contour lines you will be either climbing or descending.

On topographic maps they are indicated by brown lines and come in three types.
