In geography, the latitude of a location on the Earth is the angular distance of that location south or north of the Equator. The latitude is an angle, and is usually measured in degrees . The equator has a latitude of 0°, the North pole has a latitude of 90° north , and the South pole has a...

 for more on this). In these locations, one needs first to determine whether the sun is moving from east to west through north or south by watching its movements—left to right means it is going through south while right to left means it is going through north; or one can watch the sun's shadows. If they move clockwise, the sun will be in the south at midday, and if they move anticlockwise, then the sun will be in the north at midday.

Therefore, a more accurate fix can be made if the time of year and approximate latitude are factored in. It should also be noted that, due to the Earth's axial tilt

, no matter what your location, there are only two days each year when the sun rises precisely due east. These days are the equinox

es. On all other days, depending on the time of year, the sun rises either north or south of true east (and sets north or south of true west). For all locations the sun is seen to rise north of east (and set north of west) from the March equinox to the September equinox, and rise south of east (and set south of west) from the September equinox to the March equinox.

It should also be noted that the amount that the sun appears to be either north or south depends on both the time of year and latitude of the observer. Knowing these will enable the observer to be more precise when determining the cardinal directions from the sun's position, particularly in the early morning or late afternoon.

 was developed for ship use in scenarios where the magnetic compass simply wasn't good enough. It has the further advantages of immunity to interference by stray magnetic fields, and not depending on Earth's magnetic field at all. Its major disadvantage is that it depends on technology that many individuals might find too expensive to justify outside the context of a large commercial or military operation. It also requires a continuous power supply for its motors, and that it be allowed to sit in one location for a period of time while it properly aligns itself.

s (GPS) provided yet another means for any individual to determine true north accurately. While GPS Receivers (GPSRs) function best with a clear view of the entire sky, they function day or night, and in all but the most severe weather. The government agencies responsible for the satellites continuously monitor and adjust them to maintain their accurate alignment with the Earth. There are consumer versions of the receivers that are attractively priced. Since there are no periodic access fees, or other licensing charges, they have become widely used. GPSR functionality is becoming more commonly added to other consumer devices such as mobile phone

 within a couple of minutes of being restarted. In contrast with the gyrocompass which is most accurate when stationary, the GPS receiver must be moving, typically at more than 0.1 mph (0.2 km/h), to correctly display compass directions. Within these limitations GPSRs are considered both accurate and reliable. The GPSR has thus become the fastest and most convenient way to obtain a verifiable alignment with the cardinal directions.

. The four cardinal directions correspond to the following degrees of a compass:
  • North (N): 0° = 360°
  • East (E): 90°
  • South (S): 180°
  • West (W): 270°

An ordinal, or intercardinal, or intermediate, direction is one of the four intermediate compass directions located halfway between the cardinal directions.
  • Northeast (NE), 45°, halfway between north and east, is the opposite of southwest.
  • Southeast (SE), 135°, halfway between south and east, is the opposite of northwest.
  • Southwest (SW), 225°, halfway between south and west, is the opposite of northeast.
  • Northwest (NW), 315°, halfway between north and west, is the opposite of southeast.


These 8 words have been further compounded, resulting in a total of 16 named (and numbered) points evenly spaced around the compass. Some languages do not use compound words to name the points, instead assigning unique words, colors, and/or associations with phenomena of the natural world.

, kun readings of kanji) are used for the cardinal directions (such as minami for 南, south), but borrowed Chinese words (on readings of kanji) are used for ordinal directions (such as nan-tō for 南東, southeast).

Order of directions

While the directions can be listed in any order, most formally in clockwise or counterclockwise order, starting from some point (such as NESW, or, following the sun from daybreak in the northern hemisphere, ESWN), different languages conventionally use different orders, often using pairs of opposite directions. In English, the conventional order of the directions is "north, south, east, and west" (NSEW = N/S + E/W). In Japanese, most common is EWSN (東西南北 = E/W + S/N), and east-west (東西) is idiomatic for “everywhere, in all parts”; note that Japan is located at the extreme east of Eurasia.
