Can environmental factors affect the usability of paper maps?

Weather Conditions

Paper maps can become damaged or compromised in extreme weather conditions. Prolonged exposure to water, such as during a flood or when maps are left outdoors in the rain, can cause paper to swell and become distorted, making it difficult to read. In hot temperatures, paper can become brittle and prone to tearing.

Handling and Storage

Maps that are not properly stored or handled can also become unusable. Folding a map too many times can cause creases and tears, while being stepped on or run over can cause damage to the paper. Maps should be stored in a dry, flat area when not in use, and handled carefully to prevent damage.

Light Exposure

Prolonged exposure to sunlight or UV light can also affect the usability of paper maps. This can cause colors to fade, and the paper to become brittle, making it difficult to read. Maps should be kept out of direct sunlight and stored in a shaded area when not in use.
