3 Legend and Notes
Auspicious refers to the direction, scale and legend on the plan. Determination of direction: generally facing the plane, the top of the plane is north, the bottom is south, the left is west, and the right is east. On the plan with the navigation mark, the direction indicated by the arrow of the navigation mark is the north. Scale: the degree to which the distance on the map is smaller than the actual distance, which is called scale or scale reduction. Expressed by formula: scale = distance on map/distance on site. There are usually three ways to express the scale: numbers, that is, how many meters on the map 1 cm represent the field distance; Straight line, that is, draw a straight line on the map, indicating how many meters of field distance 1 cm on the map represents; Text-based, that is, write 1 cm directly on the map to indicate how many meters the site distance is. The decimal places are fractions, and the numerator is 1. The larger the denominator, the smaller the map scale. Legend: a symbol representing various things on a plan.
