Kita sering liat peta, dan arah mata angin selalu menunjukkan arah utara ke atas, tapi sekarang tidak selalu.
Apakah memang arah utara selalu menujukkan ke atas?

saya bingung dgn pertanyaannya. maaf, sepertinya ada kerancuan logika bahasa dalam kalimat bapak.
kalau saya sering melihat peta, arah utara pada mata angin memang selalu digambarkan ke atas. namun sekarang tidak. apakah arah utara selalu digambarkan ke atas? hampir selalu.
logikanya begini, dahulu pasangan peta adalah kompas. makanya gambar arah mata angin di peta adalah gambar jarum kompas. saat baca peta, satu tangan pegang peta satu lg pegang kompas. pertama, lihat kompas ikuti jarumnya ketemu arah utara.. buka peta sesuaikan.. enak to baca keterangan2 di petanya? kalo utara digambar ke bwh anda pasti repot baca petanya. '
nah! kalo sekarang pasangan peta adalah gps.. apakah berbeda? dan kalo kita pakai peta digital+penunjuk rute apakah masih diperlukan arah mata angin?

emang bener juga jawaban bang cupicuk, kita melihat utara menunjukkan ke atas kebanyakan di peta karena emang sampe sekarang temennya peta itu kompas juga, alasan lain juga ya karena kita mandang peta dari atas...kalo kenyataan kita berdiri terus utara nya kan gak keatas tapi ke depan, karena kalo ke atas kan bingung gimana jalannya :P

ternyata menarik juga kalau baca sejarahnya....

apalagi tentang reversed map/ Upside-Down map / South-Up map. menarik karena pada peta versi ini posisi indonesia ada di central! hehehhe... harusnya orang indonesia mengadopsi peta ini!

*loncat ke australi/NZ untuk berburu peta versi ini!!!

Map
From Wikipedia, the free encyclopedia

Orientation of maps
The Hereford Mappa Mundi, about 1300, Hereford Cathedral, England. A classic "T-O" map with Jerusalem at centre, east toward the top, Europe the bottom left and Africa on the right.

The orientation of a map is the relationship between the directions on the map and the corresponding compass directions in reality. The word "orient" is derived from Latin oriens, meaning East. In the Middle Ages many maps, including the T and O maps, were drawn with East at the top (meaning that the direction "up" on the map corresponds to East on the compass). Today, the most common – but far from universal – cartographic convention is that North is at the top of a map. Several kinds of maps are often traditionally not oriented with North at the top:

Maps from non-Western traditions are oriented a variety of ways. Old maps of Edo show the Japanese imperial palace as the "top", but also at the centre, of the map. Labels on the map are oriented in such a way that you cannot read them properly unless you put the imperial palace above your head.[citation needed]
Medieval European T and O maps such as the Hereford Mappa Mundi were centred on Jerusalem with East at the top. Indeed, prior to the reintroduction of Ptolemy's Geography to Europe around 1400, there was no single convention in the West. Portolan charts, for example, are oriented to the shores they describe.
Maps of cities bordering a sea are often conventionally oriented with the sea at the top.
Route and channel maps have traditionally been oriented to the road or waterway they describe.
Polar maps of the Arctic or Antarctic regions are conventionally centred on the pole; the direction North would be towards or away from the centre of the map, respectively. Typical maps of the Arctic have 0° meridian towards the bottom of the page; maps of the Antarctic have the 0° meridian towards the top of the page.
Reversed maps, also known as Upside-Down maps or South-Up maps, reverse the "North is up" convention and have South at the top.
Buckminster Fuller's Dymaxion maps are based on a projection of the Earth's sphere onto an icosahedron. The resulting triangular pieces may be arranged in any order or orientation.
Modern digital GIS maps such as ArcMap typically project north at the top of the map, but use math degrees (0 is east, degrees increase counter-clockwise), rather than compass degrees (0 is north, degrees increase clockwise) for orientation of transects. Compass decimal degrees can be
converted to math degrees by subtracting them from 450.




Reversed map
From Wikipedia, the free encyclopedia


A reversed map, also known as an Upside-Down map or South-Up map, is a map where south is up, north is down, east is left and west is right. Thus the Southern Hemisphere at the top of the map instead of the bottom. These maps are just as accurate as traditionally oriented maps, because the position of North at the top of maps is arbitrary. Such maps have been made in several cultures and time periods. The convention that North is at the top (and East at the right) on most modern maps was established by the astronomer Ptolemy[1] and was widely adopted by other cartographers.

In modern times, reversed maps are made as a learning device or to illustrate Northern Hemisphere bias. Different from simply turning a north-up map upside down, a reversed map has the text oriented to be read with south up. Uruguayan constructivist artist Joaquín Torres García created several works depicting a map of South America with the southern point at the top.

The famous "Blue Marble" photograph of the Earth taken from on board Apollo 17 was originally oriented with the south pole at the top, with the island of Madagascar visible just left of center, and the continent of Africa at its right. However, the image was turned upside-down to fit the traditional view.[2]

Reversed maps often have Indonesia placed in the center while Europe and the Americas are placed to the sides, although there are reversed maps centered on the Prime Meridian[3]. Ordinary north-up maps in East Asia also often have the Americas on the right, showing the Pacific ocean whole while cutting through the Atlantic ocean.

There are many other maps with non-standard orientation, such as medieval T and O maps, polar maps, and Dymaxion maps.
