Kuhi i nā latitude a me longitude
He ʻāpana o ka ʻōnaehana hoʻonohonoho hoʻonohonoho ʻāina e hiki ke hoʻomaopopo i kekahi wahi ma ka Honua. Hoʻohana kēia ʻōnaehana papahele i ka honua spherical e uhi ana i ka Honua. Hoʻokaʻawale ʻia kēia kahua i ka pahu kahi a me kēlā me kēia kuhikuhi i kēia kuʻuna e pili ana i kahi latitude a me ka lōʻihi, e like me kēlā me kēia kiko ma ka mokulele a kūloko ʻia i kekahi x a me nā koikoi. Hoʻokahele ka mahele i kēia mahele o ka Honua i ʻelua mau laina o ka laina e holo like ana i ka ebati a mai ka North Pole a i nā South Pole.
Kūlike nā laina i ka hoʻohālikelike, a me nā laina e holo ana i ka hikina i ke komohana, he mau laina latina mau ʻoe. He, kūpono lākou, kāhea ʻia. ʻO ka laina e holo kūpono ma luna o ka ekuatoru ua wehewehe i ka waiwai latitude 0. Hele i ka ʻākau i ke North Pole ka nui o ka latitude hoʻonui mai 0 ka 90 a ma ka North Pole. ʻO New York, kahi e pili ana i ka hapalua ma waena o ka ekuʻa a me ka North Pole he latitude o 40.71455. Mai ke kahe e neʻe ana i ka hema i nā waiwai Latitude e lilo i hewa ʻole a hiki i ka -90 ma South Pole. Loaʻa ka Rio de Janeiro ma ka latitude o -22.91216.
ʻO nā laina i holo i ka Pole ʻĀina a i ka Pole Hema, he waiwai mau ka lōʻihi. ʻO kēlā mau laina ua kapa ʻia he meridians. ʻO ka meridian e wehewehe i ka lōʻihi o ka waiwai 0 ke hele ma mua o Greenwich ma ʻEnelani. Ke hele nei i komohana mai Greenwich, ʻōlelo i ʻAmelika, a lilo nā kuhi lōʻihi i ka maikaʻi. E hele aku nā palena lōʻihi ma ke komohana o Greenwich mai 0 a -180 a me nā helu lōʻihi e hele ana ma ka hikina mai 0 ka 180 a me Mexico. He lōʻihi o -99.13939 a ʻo Singapore a he lōʻihi ka 103.85211.
He laʻana nā Latitude a me longitude i hoʻohana ʻia e GPSs. Ma kēlā me kēia manawa, hiki i kou wahi o kēia manawa ke wehewehe maopopo e ka latitude a me nā hoʻonohonoho lōʻihi.
