| Abstract: | According to international stipulated difference between longitude and latitude, the separate sheet of basic-scale topographic map is divided into nine types in China. On the basis of actual difference between longitude and latitude,the nine basic-scale topographic map numberings are calculated by formulas in the paper, and then the traditional graphical method continued from the past in survey teaching would be replaced by the formula method. |
