When it comes to navigating the great outdoors or exploring a new city, having a reliable map is essential. However, not all maps are created equal. Terrain maps, used for activities such as orienteering, hiking, hunting, and military operations, require a specific type of paper to withstand the demands of the environment.

Unlike sea charts, which are typically made of thick, durable material, terrain maps need to be made of a thinner paper. This is because they need to be easily handled in the field. An ideal choice for terrain maps is an 80-100 g/m2 strong MF paper, which offers good machine finishing and wet strength. This type of paper can withstand the rigors of outdoor use while still providing clear and accurate information.

One of the key considerations for terrain maps is their ability to withstand moisture. Whether it’s rain, sweat, or accidental spills, maps are bound to encounter water in outdoor settings. That’s why it’s crucial for the paper to have good wet strength. This ensures that the map remains intact and readable even when it gets wet.

In addition to its durability, the paper used for terrain maps should also have a smooth finish. This is important for two reasons. First, a smooth surface allows for better printing quality, ensuring that the map details are sharp and legible. Second, it allows for easy folding and unfolding of the map, making it convenient for users to navigate through different sections of the map.

Similarly, when it comes to city maps, the paper used must also be selected with the user’s needs in mind. While city maps are not subjected to the same rugged conditions as terrain maps, they still require a certain level of durability. Pedestrians using a city map often find themselves in conditions similar to orienteerers, needing a map that can withstand constant folding and unfolding, as well as being carried in bags or pockets.

Road maps, on the other hand, are mostly used inside vehicles and do not need to be as strong as maps used outdoors. However, they still need to be made of a durable material that can withstand repeated handling and occasional exposure to moisture. A slightly lighter paper weight can be used for road maps, as they do not need to be as rugged as terrain maps.

In conclusion, when it comes to selecting the right paper for terrain and city maps, durability and functionality are key. The paper needs to be strong enough to withstand the demands of outdoor use, while also providing a smooth surface for clear printing and easy folding.
