What are the design principles for landscape signage?

When designing landscape signage, attention should be paid to the viewing angle: that is, the angle between the observer's eyes and the line connecting the two endpoints in the long axis direction of the sign. There are four main viewing angles for scenic area signs: looking straight up, looking up, looking down, and bird's eye view. The effect of looking up makes people feel convenient, regular and orderly; the effect of looking up gives people a sense of stability, majesty, tallness and strong impact and iconicity; the effect of looking down gives people a casual and friendly feeling; the effect of looking down gives people a casual and friendly feeling; When it is 1.5 to 2 times the height of the sign, tourists can easily see the content of the sign clearly and grasp the full picture of the sign. It can be seen that when designing for a head-up view, attention should be paid to leaving enough space for sight distance. Observation angle: The angle between the observer's line of sight looking at the center point of the sign and the plane where the sign is located. Observation distance: that is, the length of the projection on the horizontal plane of the line connecting the observer's eyes to the center point of the mark. From the three elements of viewing angle, observation angle, and observation distance, three other elements closely related to the design and setting of the logo extend, namely, visual cone, height, and distance. The human visual cone is approximately 30 degrees vertically and 60 degrees horizontally.
