1. Assume that the Earth is a positive sphere. The longitude and latitude coordinates of point A and point B on the ground are (Aj, Aw) and (Bj, Bw) respectively, and the mean value of the earth's radius R is 6371 km. 2. Create a three-dimensional Cartesian coordinate system:The earth's ball center is the origin O, the ground axis is the Z axis, the Arctic direction is the positive direction of the Z axis,

Abstract: The previous chapter teaches you how to build your own administrative region map. This time, we will provide you with a visual selection of regions and the ability to automatically generate longitude and latitudeCode. ToolSource codeIt is completely open and detailed annotations are made. It can be used either as a tool or as a learning case for Baidu map API. Tool description: 1. The switch can be controlled to determine whether to c
