A cairn is a man-made pile of stones raised for a purpose, usually as a marker or as a burial mound. The word cairn comes from the Scottish Gaelic: càrn[ˈkʰaːrˠn̪ˠ].
Length is a measure of distance. In the International System of Quantities, length is a quantity with dimension distance. In most systems of measurement a base unit for length is chosen, from which all other units are derived. In the International System of Units (SI) system the base unit for length is the metre.
In everyday use and in kinematics, the speed of an object is the magnitude of the change of its position over time or the magnitude of the change of its position per unit of time; it is thus a scalar quantity. The average speed of an object in an interval of time is the distance travelled by the object divided by the duration of the interval; the instantaneous speed is the limit of the average speed as the duration of the time interval approaches zero. Speed is the magnitude of velocity, which indicates additionally the direction of motion.
North is one of the four compass points or cardinal directions. It is the opposite of south and is perpendicular to east and west. North is a noun, adjective, or adverb indicating direction or geography.
A cemetery, burial ground, gravesite or graveyard is a place where the remains of dead people are buried or otherwise interred. The word cemetery implies that the land is specifically designated as a burial ground and originally applied to the Roman catacombs. The term graveyard is often used interchangeably with cemetery, but a graveyard primarily refers to a burial ground within a churchyard.
A waypoint is an intermediate point or place on a route or line of travel, a stopping point or point at which course is changed, the first use of the term tracing to 1880. In modern terms, it most often refers to coordinates which specify one's position on the globe at the end of each "leg" (stage) of an air flight or sea passage, the generation and checking of which are generally done computationally.
Height is measure of vertical distance, either vertical extent or vertical position . For example, "The height of that building is 50 m" or "The height of an airplane in-flight is about 10,000 m". For example, "Christopher Columbus is 5 foot 2 inches in vertical height."
A milestone is a numbered marker placed on a route such as a road, railway line, canal or boundary. They can indicate the distance to towns, cities, and other places or landmarks; or they can give their position on the route relative to some datum location. On roads they are typically located at the side or in a median or central reservation. They are alternatively known as mile markers, mileposts or mile posts. A "kilometric point" is a term used in metricated areas, where distances are commonly measured in kilometres instead of miles. "Distance marker" is a generic unit-agnostic term.
A spirit level, bubble level, or simply a level, is an instrument designed to indicate whether a surface is horizontal (level) or vertical (plumb). Two basic designs exist: tubular and bull's eye . Different types of spirit levels may be used by carpenters, stonemasons, bricklayers, other building trades workers, surveyors, millwrights and other metalworkers, and in some photographic or videographic work.
A distance line, penetration line, cave line or guide line is an item of diving equipment used by scuba divers as a means of returning to a safe starting point in conditions of low visibility, water currents or where pilotage is difficult. They are often used in cave diving and wreck diving where the diver must return to open water after a penetration when it may be difficult to discern the return route. Guide lines are also useful in the event of silt out.
A memorial is an object or place which serves as a focus for the memory or the commemoration of something, usually an influential, deceased person or a historical, tragic event. Popular forms of memorials include landmark objects such as homes or other sites, or works of art such as sculptures, statues, fountains or parks. Larger memorials may be known as monuments.
Snaefell – is the highest mountain and the only summit higher than 2,000 feet (610 m) on the Isle of Man, at 2,037 feet (620.9 m) above sea level. The summit is crowned by a railway station, cafe and several communications masts.
Trail blazing or way marking is the practice of marking paths in outdoor recreational areas with signs or markings that follow each other at certain, though not necessarily exactly defined, distances and mark the direction of the trail.
Road signs in the United Kingdom and in its associated Crown dependencies and overseas territories conform broadly to European design norms, though a number of signs are unique: direction signs omit European route numbers and road signs generally use the Imperial System of units, unlike the rest of Europe. Signs in Wales and parts of Scotland are bilingual.
Diver navigation, termed "underwater navigation" by scuba divers, is a set of techniques—including observing natural features, the use of a compass, and surface observations—that divers use to navigate underwater. Free-divers do not spend enough time underwater for navigation to be important, and surface supplied divers are limited in the distance they can travel by the length of their umbilicals and are usually directed from the surface control point. On those occasions when they need to navigate they can use the same methods used by scuba divers.
A bench is a long seat on which multiple people may sit at the same time. Benches are typically made of wood, but may also be made of metal, stone, or synthetic materials. Many benches have back rests, while others do not and can be accessed from either side. Arm rests are another common feature. In many American public areas, benches may be donated by persons or associations, as indicated by an affixed plaque, a common form of memorial to a deceased person. Benches may be placed outdoors or indoors, but are more often found outdoors.
A nucleated village, or clustered settlement, is one of the main types of settlement pattern. It is one of the terms used by geographers and landscape historians to classify settlements. It is most accurate with regard to planned settlements: its concept is one in which the houses, even most farmhouses within the entire associated area of land, such as a parish, cluster around a central church, which is close to the village green. Other focal points can be substituted depending on cultures and location, such as a commercial square, circus, crescent, a railway station, park or a sports stadium.
Walking is one of the most popular outdoor recreational activities in the United Kingdom, and within England and Wales there is a comprehensive network of rights of way that permits access to the countryside. Furthermore, access to much uncultivated and unenclosed land has opened up since the enactment of the Countryside and Rights of Way Act 2000. In Scotland the ancient tradition of universal access to land was formally codified under the Land Reform (Scotland) Act 2003. In Northern Ireland, however, there are few rights of way, or other access to land.
