There are two ways to split the current graph: latitude and longitude split and rectangular split. The domestic drawing standards adopt latitude and longitude split. For details, refer to the national standard "national basic scale Topographic Map split and No. GB/T 13989-92". The main feature of the latitude and longitude split is that the row and longitude nu
