How to find the length of the topography map in kilometers?
Answers
Explanation:
A topographic map is a two-dimensional map that represents a three-dimensional area using contour lines to indicate elevation of the earth’s surface. The first means of measuring distance on a topographical map, or any map, is the straight line distance, which indicates a straight distance “as the crow flies.” This measurement is taken before calculating the slope of the land or other features that would impact the total travel distance. Learn how to measure this basic straight line distance successfully.
Lay a piece of paper down on the map and mark it. Place a straight edge of a piece of paper onto your map. Line up the edge with both the first (“point A”) and second (“point B”) points you want to measure the distance between, then make a tick mark on the paper where each point is.[1]
Make sure your piece of paper is long enough to make your 2 tick marks. Note that this method works better for shorter line distances.
Hold the edge of the paper still on the map and mark as accurately as possible where the paper lines up to your 2 points.

Answer:
To measure the straight distance::
To gauge the most limited separation between two focuses on the topographic guide along a straight line should be possible effectively with the assistance of a couple of divider. Keep the two pointed parts of the bargains over line or two focuses which must be estimated and afterward cautiously keep on scale. Note down the separation on the guide in centimeters; at that point either with the assistance of the graphical scale which is given beneath the toposheet or by utilizing the announcement scale separation can be estimated in kilometers and meters.
e.g., two spots are 5.6 km., separated on the guide.
The scale is given 2 cm. = 1 km.
1 cm. = 1/2 km.
5.6 cm. = 1/2 × 5.6
