The vertical length involving any two consecutive contours is named a contour interval. Suppose a map contains contour strains of 100 m, 98 m, 96m, and the like.
Shut Spacing: When contour traces are closely packed, it signifies a steep slope. The swift alter in elevation about a brief horizontal length creates a pronounced incline.
Contour traces always sort closed loops, both solely within the map boundaries or extending outside of them. This characteristic will help in properly depicting landforms including hills, depressions, and basins.
The bottom Element of the diagram displays some contour strains having a straight line jogging via The situation of the most value. The curve at the very best signifies the values together that straight line.
Bangladesh, Regardless of its smaller size, is densely populated, generating land a highly worthwhile asset. With the capital city Dhaka experiencing intense land scarcity, appropriate utilization of accessible land is important for infrastructural improvement.
In this process, degrees are taken at some chosen points and their degrees are lowered. Hence in this method horizontal Manage is founded initially then the amounts of People details uncovered.
When maps with contour strains became frequent, The thought distribute to other purposes.

Other measurements inside a Contour Survey include things like the orientation with the whole lot in relation for the cardinal directions, or the elevation of the land in relation to sea amount.
