1、根据所给的中国版图数据
绘制显示基于北京54坐标系的经纬度数据
编写兰勃特投影转换程序，转换上述数据，并显示
编写墨卡托投影转换程序，转换上述数据，并显示
同时，要绘制相对应的经纬网格，网格间距5度
2、根据所给的世界版图数据
绘制显示基于WGS84坐标系的经纬度数据
编写墨卡托投影转换程序，转换上述数据，并显示
计算北京(116.4，39.8)到巴黎(2.2, 48.52)的大圆轨迹，并显示
同时，要绘制相对应的经纬网格，网格间距5度(1. According to the data of China territory

Plot shows latitude and longitude data based on Beijing 54 coordinate system

Compile lambert projection conversion program, convert the above data, and display

Prepare Mercator projection conversion program, convert the above data, and display

At the same time, to draw the corresponding longitude and latitude grid, grid spacing 5 degrees

2. According to the world map data given

Draw and display longitude and latitude data based on WGS84 coordinate system

Prepare Mercator projection conversion program, convert the above data, and display

The great circle trajectory from Beijing (116.4, 39.8) to Paris (2.2, 48.52) is calculated and shown

At the same time, to draw the corresponding longitude and latitude grid, grid spacing 5 degrees)
