3 Framing of topographic maps
GB/T 13989--92
All basic scale topographic maps in my country are based on 1:1000000 topographic maps, and the map sheets are divided according to the specified longitude and latitude differences. The framing of 1:1000000 topographic maps adopts the international 1:1000000 map framing standard. The range of each 1:1000000 topographic map is 6° longitude and 4° latitude. The range between 60° and 76° is 12° longitude and 4° latitude. The range between 76° and 88° is 24° longitude and 4° latitude. There are no maps above 60° latitude that need to be combined in my country. Each 1:1000000 topographic map is divided into 2 rows and 2 columns, with a total of 4 1:500000 topographic maps. The range of each 1:500000 topographic map is 3° longitude and 2° latitude.
Each 1:1000000 topographic map is divided into 4 rows and 1 column. There are 16 11250000 topographic maps in total. The range of each 1:250000 topographic map is 1°30° longitude difference and 1° latitude difference. Each end of 111000000 topographic map is divided into 12 rows and 12 columns, with a total of 144 1:100000 topographic maps. The range of each 1:100000 topographic map is 30° longitude difference and 20° latitude difference. Each 1:1000000 topographic map is divided into 21 rows and 24 columns, with a total of 576 1:50000 topographic maps. The range of each 1:50000 topographic map is 15° longitude difference and 10° latitude difference. Each 1:1000000 topographic map is divided into 48 rows and 48 columns, with a total of 2304 125000 topographic maps. The range of each 1:25000 topographic map is 7'30\ latitude difference 5°. Each 1:1000000 topographic map is divided into 96 rows and 96 columns, with a total of 9216 1:10000 topographic maps. The range of each 1:100000 topographic map is 3°45″ longitude difference 2'30\. Each 1:1000000 topographic map is divided into 192 rows and 192 columns, with a total of 36864 115000 topographic maps. The range of each 1:5000 topographic map is 1'52,5 \, latitude difference 115\. The latitude and longitude difference, number of rows and columns and number of sheets of topographic maps of different scales are in a simple multiple relationship (see Table 1).

111000000 topographic maps adopts the international 1:1000000 map numbering standard. Starting from the equator, each latitude difference of 1 is a row, and the north and south pure 88° are divided into 22 rows, and the corresponding row numbers are represented by uppercase Latin letters (character codes) A, B, C-.V. Starting from the 180° longitude, each longitude difference of 6° from west to east is a column, and the world is divided into 60 columns, and the corresponding column numbers are represented by Arabic numerals (digital codes) 1.23, *****60. Each trapezoidal grid surrounded by longitude and latitude (see Figure 1) is a 1:1000000 topographic map, and their numbers are composed of the row number and column number of the map. For example, the map number of Beijing's 1:1000000 topographic map is 50. H

Figure 2 Numbering of the 11000000 topographic map of China 4.21:50000015000 topographic map numbering The numbering of 1500000~15000 topographic maps is based on the numbering of 1:1000000 topographic maps, using the row and column numbering method (see Figure 3). That is, the longitude and latitude differences of the topographic maps of each scale contained in the 111000000 topographic map are divided into rows and columns, with rows from top to bottom and columns from left to right. To be represented by three Arabic numerals (digital codes) in order, if less than three digits are added in front, the row number is arranged in the first place and the column number is arranged in the last place. Different characters are used as the scale code of each scale topographic map (see Table 2). The map numbers of 1:500000~15000 topographic maps are composed of the map number of the 1*1000000 topographic map, the scale code and the row and column numbers of each map sheet, a total of 1 digit code.
