Inā ʻoe e hoʻohana i kā mākou mea hana ʻimi no ka ʻimi ʻana i nā nā hoʻonohonoho palapala ʻāina o kēlā me kēia wahi GPS, e hōʻike ʻia iā ʻoe me nā helu ʻelua e like paha me ka gibberish i ka nānā mua ʻana. He mea nui ka hoʻomaopopo ʻana i ka heluhelu ʻana i kēia GPS koordinatno ka hoʻohana pono ʻana iā lākou i nā ʻōnaehana hoʻokele a i ʻole kaʻana like ʻana me nā poʻe ʻē aʻe.
ʻElua mau ʻano maʻamau
ʻElua mau ala nui e kākau ʻia ai nā hoʻonohonoho palapala:
1. Degere, minuke, a me kekona (DMS)
ʻO kēia ke ʻano kuʻuna, nautical o ke kākau ʻana i nā hoʻonohonoho. Penei kona ʻano: 41°24'12.2"N 2°10'26.5"E.
- ʻO ka poloka mua ka Latitu (ʻĀkau/ Hema).
- ʻO ka ʻāpana ʻelua ʻo ka Longitude (hikina/komohana).
- Heluhelu ia: 41 Degere, 24 Minute, 12.2 Kekona Akau.
2. Degree Decimal (DD)
ʻO kēia ke ʻano hou i hoʻohana ʻia e nā kamepiula, kelepona, a me nā mea hana e like me Google Maps. Hoʻololi ia i nā minuke a me nā kekona i hoʻokahi helu decimal. Penei kona ʻano: 41.40338, 2.17403.
I nā Degere Desimal, ʻaʻohe hua "N", "S", "E", a i ʻole "W". Akā, hōʻike ʻia ke kuhikuhi e nā helu maikaʻi a maikaʻi ʻole paha:
- Latitu: ʻO ka maikaʻi ka ʻākau o ka equator. ʻO ka hema ka ʻino.
- Lonitu: ʻO ka maikaʻi ka Hikina o ka Meridiana Nui. ʻO ke Komohana ka ʻino.
No ke aha i ʻoi aku ka maikaʻi o nā Degree Decimal
Inā pono ʻoe e kope i ka nā hoʻonohonoho palapala ʻāina o kekahi wahi GPSe hoʻouna aku i kahi hoaaloha a i ʻole e hoʻopili i kahi polokalamu, ʻoi aku ka maikaʻi o nā Degere Decimal. ʻElua wale nō helu i hoʻokaʻawale ʻia e kahi koma. ʻAʻole pono ʻoe e ʻimi i ka hōʻailona degere (°) ma kāu kīpē a i ʻole e hopohopo e pili ana i nā hewa hoʻokaʻawale e huikau ana i ka polokalamu GPS.
