Trailhead
A trailhead is the point where a trail begins or is accessed, where the trail is often intended for hiking, biking, horseback riding, or off-road vehicles. Modern trailheads often contain restrooms, maps, signposts, and distribution centers for informational brochures about the trail and its features and parking areas for vehicles and trailers. The United States Access Board defines a trailhead "as an outdoor space that is designated by an entity responsible for administering or maintaining a trail to serve as an access point to the trail." The intersection of two trails is a trail junction and does not constitute a trailhead. Historically, the cities located at the terminus of major pathways for foot traffic, such as the Natchez Trace and the Chisholm Trail, were also known as trailheads. For mountain climbing and hiking, the elevation of the trailhead above sea level Mean sea level (MSL, often shortened to sea level) is an mean, average surface level of one or more ...

Trail
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 ...

Trail Difficulty Rating System
A trail difficulty rating system, also known as walking track grading system, walk gradings or trail grades, is a classification system for trails or walking paths based on their relative technical and Physical strength, physical difficulty. A trail difficulty rating system informs visitors about the attributes of walking tracks and helps visitors, particularly those who are not usual bushwalkers, make decisions to walk on trails that suit their skill level, manage their risk, improve their experience and assist in the planning of trails and trail systems. The grading system features a recognizable criteria for visitors, so they can tell the difficulty of a certain walk, thereby allowing the walkers to determine whether they have the physical ability to attempt the walk. The width, length and surface of the trail are important factors to determine the Grade (slope), grading, in addition to natural obstacles such as rocks, ridges, holes, logs and drop-offs. The grading system is bas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |

United States Access Board
The United States Access Board (also known as the Architectural and Transportation Barriers Compliance Board) is an independent agency of the United States government devoted to accessibility for people with disabilities. The Board was created in 1973 to ensure access to federally funded facilities. It develops and maintains design criteria for the built environment, transit vehicles, telecommunications equipment, and electronic and information technology. It also provides technical assistance and training on these requirements and on accessible design and continues to enforce accessibility standards that cover federally funded facilities. The Board is structured to function as a coordinating body among federal agencies and to directly represent the public, particularly people with disabilities. Half of its members are representatives from most of the federal departments. The other half are members of the public appointed by the U.S. President, a majority of whom must have a di ...

Natchez Trace
The Natchez Trace, also known as the Old Natchez Trace, is a historic forest trail within the United States which extends roughly from Nashville, Tennessee, to Natchez, Mississippi, linking the Cumberland River, Cumberland, Tennessee River, Tennessee, and Mississippi River, Mississippi rivers. Native Americans in the United States, Native Americans created and used the trail for centuries. Early European and American explorers, traders, and immigrants used it in the late 18th and early 19th centuries. European Americans founded inns, also known as "stands", along the Trace to serve food and lodging to travelers. Most of these stands closed as travel shifted to steamboats on the Mississippi and other rivers. The heyday of the Trace began in the 1770s and ended in the 1820s, by the 1830s the route was already in disrepair and its time as a major interregional commercial route had come to an end. Today, the path is commemorated by the Natchez Trace Parkway, which follows the a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Chisholm Trail
The Chisholm Trail ( ) was a stock trail and wagon route used in the post-Civil War era to drive cattle overland from ranches in southern Texas, across the Red River into Indian Territory, and northward to rail stops in Kansas. The trail consisted of a pathway established by Black Beaver in 1861 and a wagon road established by Jesse Chisholm around 1864. "The Chisholm Wagon Road went from Chisholm's trading post on the south Canadian River (north of Fort Arbuckle) to the Cimarron River crossing, to the Arkansas River at the future site of Wichita where Chisholm had another trading post and on north to Abilene," according to the Kraisingers. By 1869, the entire trail from Texas to Kansas became known as the Chisholm Trail. Overview Texas ranchers using the Chisholm Trail had their cowboys start cattle drives from either the Rio Grande area or San Antonio. They joined the Chisholm Trail at the Red River, at the border between Texas and the Oklahoma Territory. They contin ...

Sea Level
Mean sea level (MSL, often shortened to sea level) is an mean, average surface level of one or more among Earth's coastal Body of water, bodies of water from which heights such as elevation may be measured. The global MSL is a type of vertical datuma standardised geodetic datumthat is used, for example, as a chart datum in cartography and Navigation, marine navigation, or, in aviation, as the standard sea level at which atmospheric pressure is measured to Calibration, calibrate altitude and, consequently, aircraft flight levels. A common and relatively straightforward mean sea-level standard is instead a long-term average of tide gauge readings at a particular reference location. The term ''above sea level'' generally refers to the height above mean sea level (AMSL). The term APSL means above present sea level, comparing sea levels in the past with the level today. Earth's radius at sea level is 6,378.137 km (3,963.191 mi) at the equator. It is 6,356.752 km (3,94 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Height Above Average Terrain
Height above average terrain (HAAT), or (less popularly) effective height above average terrain (EHAAT), is the vertical position of an antenna site above the surrounding landscape. HAAT is used extensively in FM radio and television, as it is more important than effective radiated power (ERP) in determining the range of broadcasts ( VHF and UHF in particular, as they are line of sight transmissions). For international coordination, it is officially measured in meters, even by the Federal Communications Commission in the United States, as Canada and Mexico have extensive border zones where stations can be received on either side of the international boundaries. Stations that want to increase above a certain HAAT must reduce their power accordingly, based on the maximum distance their station class is allowed to cover (see List of North American broadcast station classes for more information on this). The FCC procedure to calculate HAAT is: from the proposed or actual antenn ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Geography Terminology
Geography (from Ancient Greek ; combining 'Earth' and 'write', literally 'Earth writing') is the study of the lands, features, inhabitants, and phenomena of Earth. Geography is an all-encompassing discipline that seeks an understanding of Earth and its human and natural complexities—not merely where objects are, but also how they have changed and come to be. While geography is specific to Earth, many concepts can be applied more broadly to other celestial bodies in the field of planetary science. Geography has been called "a bridge between natural science and social science disciplines." Origins of many of the concepts in geography can be traced to Greek Eratosthenes of Cyrene, who may have coined the term "geographia" (). The first recorded use of the word γεωγραφία was as the title of a book by Greek scholar Claudius Ptolemy (100 – 170 AD). This work created the so-called "Ptolemaic tradition" of geography, which included "Ptolemaic cartographic theory ...
