Trail Maps
A trail map is a map used to aid in navigation and can symbolize an assorted amount of information of a particular area or contain only a single representation of the data it represents. Overview Trail maps are produced in a variety of map scale, scales, sizes, formats, and media, depending on the audience and purpose of the map. Some trail maps have been extensively edited for content giving detail about nearby features, places of interest, or interesting facts, while some maps may only give minimal information of the trail. Hiking sometimes requires planning. Some web sites offer hikers necessary preparation “must-haves” when packing for a trip as well as information about various trails around the country. Included in the list of these essentials is the trail map. Navigating through, to, and away from people's destinations require, in many instances, the use of maps, descriptions of or around those places, and/or a combination of these displayed on paper or through today ...

Map Scale
The scale of a map is the ratio of a distance on the map to the corresponding distance on the ground. This simple concept is complicated by the curvature of the Earth's surface, which forces scale to vary across a map. Because of this variation, the concept of scale becomes meaningful in two distinct ways. The first way is the ratio of the size of the generating globe to the size of the Earth. The generating globe is a conceptual model to which the Earth is shrunk and from which the map is projected. The ratio of the Earth's size to the generating globe's size is called the nominal scale (also called principal scale or representative fraction). Many maps state the nominal scale and may even display a bar scale (sometimes merely called a "scale") to represent it. The second distinct concept of scale applies to the variation in scale across a map. It is the ratio of the mapped point's scale to the nominal scale. In this case 'scale' means the scale factor (also called point scal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hiking Equipment
Hiking equipment is the equipment taken on outdoor walking trips. The duration, distance, planned activities, and environment impacts equipment selection. For example, a short day hike across flat farmland versus trekking in the Himalayas would call for different types of equipment. Planning According to Tom Brown, the order of survival is shelter (including clothing), water, fire, and food. Cody Lundin writes about the "Rule of 3s" and states three minutes without air, three hours without shelter, three days without water, or three weeks without food will result in not surviving. Considerations for selecting hiking equipment: * Length and remoteness of trip * Weight hiker can carry * Capacity of equipment * Medical needs * Weather (e.g., temperature range, sun/shade, rain, snow, ice) * Terrain (e.g., trail conditions, cliffs, sand, swamp, river crossings) * Shelter * Clothes * Water * Food * Protection from animals (e.g., insect repellent, mace, bear spray, bear-r ...

Trails
A trail, also known as a path or track, is an unpaved lane or a small paved road (though it can also be a route along a navigable waterways) generally not intended for usage by motorized vehicles, usually passing through a natural area. However, it is sometimes applied to highways in North America. In the United Kingdom and Ireland, a path or footpath is the preferred term for a pedestrian or hiking trail. In the US, the term was historically used for a route into or through wild territory used by explorers and migrants (e.g. the Oregon Trail). In the United States, "trace" is a synonym for trail, as in Natchez Trace. Some trails are restricted to use by only walkers, or cyclists, or equestrians, or for snowshoeing, or cross-country skiing, others, for example bridleways in the UK, are shared, and can be used by walkers, cyclists and equestrians. Although most ban motorized use, there are unpaved trails used by dirt bikes, quad bikes and other off-road vehicles, u ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
