Nomenclature of topographical map |
Nomenclature (map sheet title) of topographic maps depends on their scales. The following scales of topographic maps exist: - 1: 1 000 000, - 1: 500 000, - 1: 200 000, - 1: 100 000, - 1: 50 000, - 1: 25 000, - 1: 10 000. - 1: 5 000.
Template of Nomenclature of 1:10 000 map looks like: 9 . Z - 99 - 999 - 9 - 9 - 9 1 . 2 - 34 - 567 - 8 - 9 - 10
Dot or dash may be used as delimiter. 1 symbol means northern or southern hemisphere and accepts value: 0 - northern; 1 - southern. Symbol 2 denotes «Latitude zone» or Row (Latin character from A to U). 3,4 symbols. «Longitude zone» or Column (Integer from 1 to 60). Numbering is starting from meridian of 180 degrees. Accept the values from 1 to 60, increasing in the direction of the east. Symbols 5,6,7 denotes the number of the map sheet of scale 1 : 100 000. If the map sheet of scale 1 : 1 000 000, accepts values from 1 to 144. If the map sheet of scale 1 : 200 000, accepts values from 1 to 36 (respectively 5,6-th symbol). If the map sheet of scale 1 : 500 000, accept values from 1 to 4 (respectively 5-th symbol). Symbol 8 - a location of a map sheet of scale 1: 50 000. At ruling a map sheet of scale 1:100 000, accepts values from 1 to 4. Symbol 9 - a location of a map sheet of scale 1: 25 000. At ruling a map sheet of scale 1:50 000, accepts values from 1 to 4. Symbol 10 - a location of a map sheet of scale 1: 10 000. At ruling a map sheet of scale 1:25 000, accepts values from 1 to 4.
Examples of nomenclatures of topographic maps are given in the table 1.
Table 1 - Sizes of maps sheets of DTM of Russia
Table 2 - Sizes of double, triple and quadruple sheets of maps of DTM of Russia
You can create twin, triple, and quadruple sheets only within the one six-degree zone. For maps of scale 1:1 000 000 the creation of double and quadruple sheets is not provided. To create a double/quadruple sheet at a scale of 1:1 000 000 you need to create two/four separate map sheets in the MAP format and open them within the same working window of the application. To create a double/quadruple sheet at a scale of 1:1 000 000 you must use the «Free nomenclature» option. In this case, the corner points of the frame are entered manually. You can add deflection points for the frame using the «Map Editor» task.
