Quick Answer
When selecting a waterproof map, look for one that is laminated or coated with a waterproof material, has a clear and legible design, and is large enough to provide detailed information without being cumbersome.
Choosing a Waterproofing Method
When it comes to waterproof maps, the method used to apply the waterproof coating is crucial. Lamination is a popular choice, as it involves sandwiching the map between two layers of plastic. This method is effective but can be prone to delamination over time. Another option is to apply a waterproof coating, such as a polyurethane or silicone-based treatment, directly to the map. This method is more durable but can be more expensive.
Map Size and Scale
A waterproof map should be large enough to provide detailed information without being cumbersome. A good rule of thumb is to choose a map with a scale of 1:50,000 to 1:100,000, which offers a balance between detail and portability. For example, a map of the Appalachian Trail might have a scale of 1:50,000, while a map of a smaller wilderness area might have a scale of 1:20,000.
Map Features and Durability
In addition to being waterproof, a good map should also have a clear and legible design, with easy-to-read text and symbols. The map should also be durable enough to withstand rough handling and harsh weather conditions. Look for maps made with high-quality paper or synthetic materials, and consider features such as tear-resistant construction and a durable binding system.
