In the following methods of relief depiction, which one is not a quantitative method?

Question

Accepted Answer

Hachure is not a quantitative method of relief depiction because it relies on the subjective judgment of the cartographer to represent slope steepness. Hachures are short lines drawn in the direction of the steepest slope; their thickness and density increase with the steepness of the slope. However, there is no precise numerical relationship between the hachure characteristics and the actual slope angle. It's a qualitative, visual representation.

Here's why the other options are incorrect:

*   **Spot height:** Spot heights are points on a map with a known elevation. They provide a precise numerical value for the elevation at that specific location, making it a quantitative method.

*   **Bench Mark:** Benchmarks are permanently fixed points with precisely determined elevations, established by surveying. They provide accurate numerical data about elevation, thus are quantitative.

*   **Contours:** Contours are lines connecting points of equal elevation. The spacing between contours indicates the slope's steepness, and the contour values themselves represent specific elevations. This provides quantitative information about the terrain's elevation and slope.
