Question

Answer

Contour Interval

Contour interval is an important concept in cartography and topography. It refers to the vertical distance between two consecutive contour lines on a map or a plan.

Explanation

- Contour lines are imaginary lines on a map that connect points of equal elevation. They are used to represent the shape and relief of the land surface.
- Contour interval is the vertical distance between two consecutive contour lines. It is usually expressed in feet or meters, depending on the units used in the map or plan.
- A larger contour interval means that the elevation difference between two contour lines is greater, while a smaller contour interval means that the elevation difference is smaller.
- Contour interval is an important factor in determining the accuracy and detail of a topographic map. A map with a small contour interval will show more detail and accuracy, while a map with a larger contour interval will show less detail and accuracy.
- Contour interval is also used to calculate the gradient or slope of the land surface. The steeper the slope, the closer the contour lines will be to each other.
- In addition to vertical distance, horizontal distance between two points on the same contour line is also important in topography. This distance is called horizontal equivalent or horizontal distance.
- The contour interval is an important factor in determining the accuracy and detail of a topographic map. A map with a small contour interval will show more detail and accuracy, while a map with a larger contour interval will show less detail and accuracy.

Conclusion

In conclusion, contour interval is the vertical distance between two consecutive contour lines on a map or a plan. It is an important factor in determining the accuracy and detail of a topographic map and is used to calculate the gradient or slope of the land surface.
