ʻO kahi kumu kūponoʻole
ʻElua mau makahiki i hala aku nei, ma ka ʻaha kūkā makahiki o "Ka hoʻouluʻana a me ke kiʻi” Mai ʻAmelika Hui Pū ʻIa, hoʻomanaʻo wau i ka ʻike ʻana i kekahi o kēlā mau uahi e haʻalele iā ʻoe me ka ʻōlelo ʻole, ʻaʻole wale no ka mea ʻaʻole kūpono kā mākou haʻawina ʻōlelo Pelekane i ka gringo caliche. E pili ana ia i kahi hōʻikeʻike o Kevin Sahr, Jon Kimerling a me Denis White i kā lākou hōʻikeʻike "Nā Pūnaewele Mālama Kūloheloheʻo Geodesic Discrete Global", ʻo ia hoʻi ma kā mākou ʻōlelo Latin:
Ke kuʻinaʻaʻole i kauʻia ma luna o nā kiʻi.
ʻO ka hana nui a ka poʻe kūkulu hale geodesy ʻo ia ka hoʻololi ʻana i kahi ʻili hemispherical i kahi huahana hope loa o ke ʻano rectangular, aneane pau nā geodesic projections i manaʻo ʻia ma ke kumu kumu i hana ʻia ai lākou, a ʻo ia ka "paʻi palapala", ʻo ia hoʻi. No ke aha i lilo ai kēia mau ʻāpana like ʻole o nā ellipsoids i kahi ʻāpana ʻehā a nona ke kumu nui he ʻumikumamālima makahiki i hala aku nei e hiki ke paʻi i ʻelua palapala ʻāina ma ka pālākiō like a hiki ke hui pū me lākou ma ko lākou mau ʻaoʻao.
Hoʻokumu ʻia ka noi a kēia mau keonimana i ka paio, i kēia wā o ka ʻenehana, ʻaʻole ʻo ke paʻi wale ke kumu wale nō e hoʻokaʻawale ai mākou i ka geometry quher-spherical o ka honua, akā no nā hana geolocation; E like me ka hoʻopili ʻana o nā pono hana GIS / CAD a me nā polokalamu kelepona i ka hoʻohana ʻenehana, ʻaʻole liʻiliʻi ka pono no nā helu geolocation paʻakikī. Hana ʻia kēia anamanaʻo i ka pili e noʻonoʻo ai i ka anakahi liʻiliʻi o ka ʻike geodetic i loko o ka huinakolu me nā kihi i kāwili ʻia, ʻo ia ka hoʻoponopono e loaʻa i kēia triangle ma muli o ka curvature o ka honua, no laila ʻaʻole ia he mea ʻē aʻe o ka ʻāpana o ka ʻili, me nā lihi hoʻoponopono i ka curvature o ka honua a nona ke kikowaena e kūlike i kahi kikowaena noʻonoʻo o ka honua, a i ʻole ka laina polar o ka spheroid.
Ka uahi maikaʻi e kū'ē i ke kumukūʻai e lilo iā mākou no ka hoʻomaopopo i ka mana o Mercator ma ka papahana Geodesy class.
