Contour 16 character formula

Contour formula: the same line is the same height, and the same figure is equidistant. Dense and steep, convex and low are ridges, overlapping is cliffs, big and small, big and small, big and small.

Other jingles?

Contour jingle: contour line, out of altitude, marked at the peak; The steep slope is dense and gentle, and there is a saddle between the two mountains; Lower curved ridge, upper curved valley and cliff are at the intersection.

explain

"Contour line, elevation" means that the basic basis of contour line is elevation, and points with the same elevation are connected into a line to form contour line. All points on the same contour line have the same elevation.

"The mountain peak is marked" means that the place where the mountain peak is located is clearly marked in the picture, usually marked with a solid black triangle.

"Steep slope is dense and gentle slope is sparse", where the slope is large, the contour lines are dense and the line spacing is small, and vice versa.

"There is a saddle between two mountains", and between two adjacent peaks, there is the saddle.

"downward curved ridge, upward curved valley" and "downward curved valley" are a set of contour lines that bend to the low altitude direction, that is, the position of the ridge; "Upward bend" is a set of contour lines that bend in the direction of high altitude, and it is where the valley lies.

"Cliff at the intersection", contour lines cannot intersect. If the contour lines are very close and visually "intersect", then this place is where the cliff is.
