The precision of the latitude part does not increase so much, more strictly however, a meridian arc length per 1 second depends on the latitude at the point in question. The discrepancy of 1 second meridian arc length between equator and pole is about 0.3 metres (1 ft 0 in) because the earth is an oblate spheroid .
A GPS unit at confluence 53N 0, in Lincolnshire, England. The Degree Confluence Project is a World Wide Web-based all-volunteer project that aims to have people visit each of the integer degree intersections of latitude and longitude on Earth, posting photographs and a narrative of each visit online.
A geographic coordinate system (GCS) is a spherical or geodetic coordinate system for measuring and communicating positions directly on Earth as latitude and longitude. [1] It is the simplest, oldest and most widely used type of the various spatial reference systems that are in use, and forms the basis for most others.
In the preview, click on the template and you will get to the Map sources page. There, the degrees-only geographical coordinates are converted into degrees-minutes-seconds anyway and displayed automatically at the top of the page, so you can still decide if you want to convert the degrees-only-geographical coordinates into the degree-minutes ...
The numerical values for latitude and longitude can occur in a number of different units or formats: [2] sexagesimal degree: degrees, minutes, and seconds : 40° 26′ 46″ N 79° 58′ 56″ W; degrees and decimal minutes: 40° 26.767′ N 79° 58.933′ W; decimal degrees: +40.446 -79.982; There are 60 minutes in a degree and 60 seconds in a ...
The WGS 84 meridian of zero longitude is the IERS Reference Meridian, [8] 5.3 arc seconds or 102 metres (335 ft) east of the Greenwich meridian at the latitude of the Royal Observatory. [ 9 ] [ 10 ] (This is related to the fact that the local gravity field at Greenwich does not point exactly through the Earth's center of mass, but rather ...
The ordinate y of the Mercator projection becomes infinite at the poles and the map must be truncated at some latitude less than ninety degrees. This need not be done symmetrically. Mercator's original map is truncated at 80°N and 66°S with the result that European countries were moved toward the centre of the map.
Longitude: from West to East this map definition covers 59 degrees. At an image width of 200 pixels, that is 0.295 degrees per pixel. At an image width of 1000 pixels, that is 0.059 degrees per pixel. Latitude: from North to South this map definition covers 21 degrees. At an image height of 200 pixels, that is 0.105 degrees per pixel.
