Ua ʻike mākou a pau i ka pop-up: "example.com makemake e ʻike i kou wahi." Inā ʻoe e kaomi i ka ʻae, ʻike pinepine ka pūnaewele i kou kūlana pololei i loko o kekona. Akā inā ʻoe e hoʻohana nei i kahi pona me ka ʻole o kahi puʻupuʻu GPS, pehea e ʻike ai i hea ʻoe i pololei loa?
ʻO HTML5 Geolocation API
Hoʻohana nā polokalamu kele pūnaewele hou i kahi maʻamau i kapa ʻia ʻo HTML5 Geolocation API. ʻAʻole ʻike kēia API i kou wahi ponoʻī; aka, he elele no ia. Nīnau ia i ka ʻōnaehana hana o ka mea hana (Windows, macOS, iOS, Android) e noʻonoʻo i hea ia, a laila hoʻihoʻi i kēlā mau hoʻonohonoho i ka pūnaewele.
Pehea e ʻike ai ka ʻōnaehana hana iā ʻoe
Hoʻohana kāu hāmeʻa i ka hui ʻana o nā ala e hoʻoholo ai i kona wahi, i kapa ʻia ʻo Location Services. E hoʻāʻo ʻo ia i nā ala pololei loa, a e hoʻi i nā ala pololei ʻole inā pono:
- GPS: Inā aia ʻoe ma ke kelepona hele ma waho, e hoʻohana ka mea hana i kāna chip GPS i kūkulu ʻia e kamaʻilio me nā satelite. ʻO kēia ke ala pololei loa.
- Wi-Fi Positioning System (WPS): Inā ʻoe ma ka pona, ʻo ia ke ala maʻamau. Nānā kāu kamepiula i nā pūnaewele Wi-Fi kokoke loa (ʻo ia hoʻi nā mea āu i pili ʻole ai). Hoʻouna ʻo ia i nā inoa (SSID) a me nā hōʻailona ikaika o kēia mau pūnaewele i kahi waihona (hoʻokele pinepine ʻia e Google a i ʻole Apple). Ma muli o ka palapala ʻana o kēia mau hui i nā wahi o nā miliona o nā mea ala Wi-Fi ma ka honua holoʻokoʻa, hiki iā lākou ke hoʻokaʻawale i kou kūlana me ka pololei haʻalulu—pinepine i loko o kekahi mau mika.
- Cell Tower Triangulation: Ma nā polokalamu kelepona, hiki i ka OS ke hoʻoholo i kou wahi ma muli o kou mamao mai nā hale kiaʻi kelepona kokoke.
- Helu IP: Inā hāʻule nā mea ʻē aʻe, e hoʻi ka ʻōnaehana i ka hoʻohana ʻana i kāu leka uila IP e koho i kou kūlanakauhale a i ʻole ka ʻāina.

No ka pololei loa o ka geolocation o ka polokalamu kele pūnaewele (mahalo i ka nānā ʻana i ka Wi-Fi), ua hoʻolālā ʻia nā polokalamu kele pūnaewele ʻaʻole e kaʻana like i kēia ʻike me ka ʻole o kāu ʻae ʻae. Inā hōʻole ʻoe i ka ʻae pūnaewele, e ālai ka Geolocation API i ka noi, a e hāʻule ka pūnaewele i ka manaʻo ʻana i kou wahi ma o kāu IP address.
