Nothing affects so much the use of a working topographic map as its careless folding. Correct folding of the paper working topographic map ensures convenient placement of the map in a tablet or field bag. Using the card without fully deploying it, quickly finding the required area on the map, saving the card from premature wear.
The correct folding of the paper working topographic map, the form and handling of the folded map.
The shape of the folded paper working topographic map may be different. It depends on the scale of the map, as well as on the conditions under which it will be used. For classes in the classroom, a folded work card usually should fit the size and shape of the classroom table. When working on the ground, it is advisable that the work card be folded in accordance with the shape and size of the tablet or field bag.
The shape of the folded paper working topographic map is also affected by the nature of the upcoming combat mission. So, for example, if you have to make a march, the shape of the folded card will differ from the form of folding the card in a defensive battle. Having laid out a glued card on the table, they first determine the area of upcoming military operations.
Determination of the area of forthcoming actions on the topographic map before folding.
Then, orienting the map in the direction of the enemy or along the route of the upcoming movement, proceeding from the width of the field bag or tablet, bend the parts of the map that are unnecessary for work from both sides. Then fold it with an accordion and put it in a field bag or tablet. Turning the links of a folded map towards the enemy or in the direction of movement, like a book, you can conveniently work with the map without fully deploying it.
A working paper card should not be folded along the line of gluing, since immediately the card will break in these places. The dense folding of the paper working topographic map provides the best conditions for working on it. In order to prevent wrinkling of sheets and bulges formed from the air remaining between the folded sheets of the card, it is recommended to carefully smooth the gluing of the working card folded into a certain shape.
When smoothing a paper work topographic map, you must carefully use a ruler or other solid object. Since due to the remnants of dried glue in the places of gluing sheets, you can get injured. A correctly folded card ensures its long-term preservation and suitability for work. It should be borne in mind that good results when working on the map are obtained if there is a solid, even base under the sheets of the map.
Therefore, tablets for the work card are recommended to be made of cardboard, plastic or other dense material. During prolonged work on one part of gluing together or on one sheet of the map, especially during extra-weather weather, it is recommended to cover the map sheets with tracing paper or wax, on which the environment data can be applied with colored pencils.
