Outdoor common terrain

The outdoor terrain is very complex and difficult to quantify. According to limited personal experience, we have divided it into eleven types, hoping to give new people who have just entered the outdoors with some help. We also look forward to the correctness of veterans.

1. Dome Hill: The contour lines are loose, close to the ring, and represent independent hillocks that rise around or rise close to high ground.

Second, the conical hill: contour line into a circular line, the higher the nearer, denser, more common in the mountains, shaped like a cone.

Third, the amount of mountain: near the steep slope of the top of the hill, the slope suddenly flattened out, shaped like a person, after which reached the top contour of the hill that this part is particularly wide and bent down.

4. Inclined lands: slopes that are low and shallow, or plains that extend into shallow, shallow parts of the highlands. They are often water-flowing, with ribs separating on both sides, and are very similar to valleys. Outdoor common terrain

V. Steep wall: The ridgeline is broad and steep at the end and is called a steep wall. It is near the river valley or the coast. The contour line is particularly dense here.

6. Mountain shoulders: The upper or lower part of the ridgeline appears to be anxious, but the middle part is flattened. It is called the shoulder of the mountain. The contour line indicates that the central part is particularly wide.

7. Mountain ridge: It is a narrow and long high-lying highland. The top may be flat, broad or knife-edge, etc. The slopes on both sides may be uniform, or one side may be straight, one side may be gentle, and the other may be seen in the wide flat. In the area, in addition, the terrain is taller and longer than the surrounding area, and it can also be regarded as a ridge. The contour line indicates that the ridge is an elliptical line.

8. Hawthorn: Located on a narrow, low-lying location between two mountains, rivers diverge from each other, and there are no clear distinctions from the saddles. They are usually narrow and steep on both sides of the saddle. It is often rare to make crossroads on this mountain to represent the mountains and bend up from the low ground. Outdoor common terrain

Nine, saddle: It is also the shallow ridge between two mountains on the ridge, but slightly higher than the foothills.

10. Interlaced mountains: In the young valleys, when the rivers are curved, the ridges on both sides of the river will protrude toward each other and form a jagged, prominent ridgeline, gentle slope, concave ridgeline, steep slope The contour lines indicate the ridges protruding from the river bank, and they are bent down at a little distance from the river bank. Conversely, they represent concave mountain ridges, and they are bent out of the river bank. Outdoor common terrain

XI. Cliffs: For a high and almost vertical rock face, it is mostly formed by two major functions of erosion and faults; both inland and coastal, and the contour line represents the wall of the wall. There can be many contours that are coincident. But there are also special symbols.
