1. The basic contents of interpretation of the solar altitude map, such as the interpretation of the solar altitude map, are: the geographical coordinates of the sun’s direct point; the distribution of the sun’s height, the distribution of the height of the sun at noon; the local time, the calculation of Beijing time; the midday sun Calculation of the size of the height; changes in the length of the day and night; dates (dates), seasons, and geographical phenomena related to the time of the figure. The solar height map can be viewed as a top view with the sun’s direct point as the center. The following methods must be mastered when interpreting, which will help to solve the problem correctly:
