This was known as running down a westing if westbound, or easting if eastbound. [2] In Farley Mowat's book Westviking, he gives examples from the Norse Sagas of Vikings using this practice to hop reliably from Norway to the Faroes, then Iceland, then Greenland, then North America, and then back to Ireland, with very primitive instruments.
Informally, specifying a geographic location usually means giving the location's latitude and longitude.The numerical values for latitude and longitude can occur in a number of different units or formats: [2]
To avoid dealing with negative numbers, a false Easting of −500 000 meters is added to the central meridian. Thus a point that has an easting of 400 000 meters is about 100 km west of the central meridian. For most such points, the true distance would be slightly more than 100 km as measured on the surface of the Earth because of the ...
This consists of up to 2 digits (6-degree longitude UTM zone) for West to East, followed by a letter (8-degree latitude band) from South to North; in this example, "18S". [10] [11] 100,000-meter (100 km) Square Identification; for regional areas. This consists of two letters, the first West to East, the second South to North; in this example, "UJ".
Direction determination refers to the ways in which a cardinal direction or compass point can be determined in navigation and wayfinding.The most direct method is using a compass (magnetic compass or gyrocompass), but indirect methods exist, based on the Sun path (unaided or by using a watch or sundial), the stars, and satellite navigation.
This almanac is one of the sources used by Amerigo Vespucci in his landmark longitude calculations he made on August 23, 1499 and September 15, 1499 as he explored South America. [38] [39] [40] The method was published by Johannes Werner in 1514, [41] and discussed in detail by Petrus Apianus in 1524. [42]
1234 5678 (numerical location; easting is 1234 and northing is 5678, in this case specifying a location with 10 m resolution) An MGRS grid reference is a point reference system. When the term 'grid square' is used, it can refer to a square with a side length of 10 km (6 mi), 1 km, 100 m (328 ft), 10 m or 1 m, depending on the precision of the ...
