Kuyamba kwa maubwenzi amtunda wamtunda ndi mtunda

Magawo a kutalika ndi kutalika ndi gawo limodzi la magawo omwe amatha kudziwa malo aliwonse padziko lapansi. Dongosololi limagwiritsa ntchito malo ozungulira omwe amapanga Dziko Lapansi. Malo awa agawika mu gululi ndipo mfundo iliyonse pamtunda iyi ikufanana ndi kutalika kwakatali ndi kutalika, monga lingaliro lililonse pa ndege ya cartesian limafanana ndi x ndi y mogwirizana. Gawo ili limagawika padziko lapansi ndi mizere iwiri yomwe imayenderana ndi equator komanso kuchokera ku North Pole kupita ku South Pole.

Mizere yofananira ndi equator, ndi mizere yomwe imayambira kummawa kupita kumadzulo, ili ndi gawo la mtunda wokhazikika. Amakhala, mokwanira, amatchedwa kufanana. Mzere womwe umayang'ana pamwamba pa equator umatanthauzira kufunika kwa kutalika 0. Kupita kumpoto chakumpoto kwa North Pole mtengo wamitunda umakwera kuchokera pa 0 mpaka 90 ku North Pole. New York, yomwe ili mtunda wapakati pakati pa equator ndi North Pole yakhala ndi kutalika kwa 40.71455. Kuchokera ku equator kupita kumwera, chikhalidwe chamtunda chimakhala chosayenera ndikufika -90 ku South Pole. Rio de Janeiro ali ndi latitude wa -22.91216.

Mizere yomwe imayambira North Pole kupita ku South Pole imakhala ndiutali wamtali. Mizere imeneyo imatchedwa meridians. Meridian yomwe imalongosola kutalika kwa mtengo 0 imadutsa Greenwich ku England. Kupita kumadzulo kuchokera ku Greenwich, titi cha ku America, matalikidwe azikhala opanda pake. Mitengo yayitali kumadzulo kwa Greenwich imachokera ku 0 mpaka -180 ndipo matalikidwe akum'mawa opita kum'mawa amachokera ku 0 mpaka 180. Mexico City ili ndi kutalika kwa -99.13939 ndipo Singapore ili ndi kutalika kwa 103.85211.

Magulu a Latitidwe ndi kutalika ndi mapangidwe omwe amagwiritsidwa ntchito ndi GPS. Nthawi ina iliyonse, malo omwe muli omwe akufotokozedwazi akhoza kufotokozedwa ndendende ndi magulu amtunda ndi kutalika.
