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 distortion of the projection. UTM eastings range from about 166 000 meters to 834 000 meters at the equator.
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]
The area is divided into 100 km squares, each of which is denoted by a two-letter code. Within each 100 km square, a numerical grid reference is used. Since the Eastings and Northings are one kilometre apart, a combination of a Northing and an Easting will give a four-digit grid reference describing a one-kilometre square on the ground.
The more distant hemisphere is projected above the north pole and below the south pole. The equator bisects Africa, crosses South America and then continues onto the complete outer boundary of the projection; the top and bottom edges and the right and left edges must be identified (i.e. they represent the same lines on the globe).
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]
For example, a Mercator map printed in a book might have an equatorial width of 13.4 cm corresponding to a globe radius of 2.13 cm and an RF of approximately 1 / 300M (M is used as an abbreviation for 1,000,000 in writing an RF) whereas Mercator's original 1569 map has a width of 198 cm corresponding to a globe radius of 31.5 cm and an ...
The Americas, also known as America, [1] are lands of the Western Hemisphere, composed of numerous entities and regions variably defined by geography, politics, and culture. The Americas are recognized in the English-speaking world to include two separate continents: North America and South America.
