What Is a Slope Map?
The slope map is a map showing the slope of the ground. The halo line or color is used to directly indicate the magnitude or steepness of the slope on the graph.

- The slope map is a map showing the slope of the ground. The halo line or color is used to directly indicate the magnitude or steepness of the slope on the graph. The formula for calculating the slope angle () is:
- tg = h / l
- Where h is the height difference and l is the horizontal distance. The form of the slope value is usually expressed by the angle between an inclined surface and the horizontal plane, that is, the angle of inclination; it can also be expressed by the fractional formula or percentage of the ground. Compilation of the slope map is based on the topographic map with contour lines. Generally, a large scale chart has a slope rule below the outline. The horizontal distance between the contour lines corresponding to the slope values of the various levels can be used. Out of all grades. In actual mapping, slope contours are often graded on topographic maps using a contour line density ruler. The grading standards are mostly determined according to the critical limits of slopes that people actually need to transform and use, or the natural limit values of geographical features. The slope map has important practical value in agriculture, forestry, water conservancy construction, and military.
