GPS Coordinates

Izixhumanisi ze-GPS ziyizinombolo ezichaza noma iyiphi indawo eMhlabeni zisebenzisa i-latitude nobude. Ziyisisekelo sawo wonke amamephu, uhlelo lokusebenza lokuzulazula, isevisi yesimo sezulu, nesistimu yokulethwa oyisebenzisayo. Uma usuqonda ukuthi zisebenza kanjani, ungakhomba, wabelane, futhi uthole noma iyiphi indawo emhlabeni ngokuzethemba — azikho izimpawu zendawo noma amagama emigwaqo adingekayo.

I-Latitude kanye ne-Longitude

Cabanga ngoMhlaba osongwe ngegridi engabonakali. Imigqa ye-Latitude igijima enyakatho-eningizimu: 0° ihlala inkabazwe futhi ikhuphukela ku-±90° ezigxotsheni. I-Longitude imigqa isuka empumalanga–ntshonalanga: 0° ihlala ku-prime meridian (edlula e-Greenwich, e-London) futhi ifinyelele kufika ku-±180° ngakolunye uhlangothi lwembulunga. Ndawonye, ​​lezi zinombolo ezimbili zichaza iphuzu elilodwa ncamashi - yonke indawo eMhlabeni inepheya yayo ehlukile yokuhlanganisa, futhi azikho izindawo ezimbili ezabelana ngeyodwa.

Izimpawu ezinhle nezingezinhle (noma izinhlamvu N/S kanye no-E/W) zikutshela ukuthi ukuyiphi i-hemisphere. I-latitude engu-40.7 isenyakatho nenkabazwe; i-longitude engu -74.0 isentshonalanga ye-prime meridian.

Coordinate Formats

Indawo efanayo ingabhalwa ngezindlela ezingaphezu kweyodwa. Okubili ozohlangana nakho kakhulu yilezi:

• Amadigri eDesimali (DD): 40.7128, -74.0060
• Amadigri, Amaminithi, Amasekhondi (DMS): 40° 42' 46" N, 74° 0' 21" W

Amadigri amadesimali ayifomethi yokuya kuyo yamawebhusayithi, izinhlelo zokusebenza, nezizindalwazi ngoba kulula ukukugcina nokuqhathanisa. I-DMS ifomethi yakudala esetshenziswa kumashadi asolwandle namayunithi amadala e-GPS. Zombili zichaza indawo efanayo - ziyizindlela ezihlukile zokubhala izinombolo ezifanayo.

Kungani Ukunemba Kubalulekile

Indawo ngayinye yedesimali eyengeziwe yenza ukuxhumanisa kucace kakhudlwana. Njengomhlahlandlela ojwayelekile:

1. Amadesimali amathathu akwenza ucishe usayizi wendawo.
2. Amadesimali amane ayawenza abe yibhilidi cishe elilodwa.
3. Amadesimali amahlanu noma ayisithupha akubeka phakathi kwamamitha ambalwa - okwanele ukumaka umnyango noma ibhentshi lasepaki.

Kungakho ukwabelana ngezindawo zamadesimali ezanele kubalulekile uma ufuna ukuthi othile athole indawo okuyiyonayona kunendawo ejwayelekile.

Uzithola Kanjani Izixhumanisi ze-GPS

Ukuthola izixhumanisi kulula. Sebenzisa isitholi sezixhumanisi ze-GPS ukuze uchofoze noma iyiphi indawo kumephu futhi ufunde i-latitude nobude bayo, noma uvule ithuluzi lendawo ye-GPS ukuze uthole izixhumanisi zalapho ukhona njengamanje. Kokubili kukuvumela ukuthi ukopishe umphumela ngokuthepha okukodwa ukuze uwunamathisele kumlayezo, kuhlelo lokusebenza lwamamephu, noma efomini. Noma ngabe uhlela ukuqwala izintaba, umaka iphoyinti lomhlangano, noma wanelisa nje ilukuluku lakho, izixhumanisi zikunikeza indlela eqondile, yendawo yonke yokuchaza noma iyiphi indawo eMhlabeni.

Ukusetshenziswa Kwansuku zonke Kwezixhumanisi

Izixhumanisi akuzona nje ezabahloli kanye namatilosi - zixazulula izinkinga zansuku zonke futhi. Ngenxa yokuthi zichaza indawo ngaphandle kokuthembela emagameni emigwaqo, zikhanya noma kuphi lapho ikheli lifinyelelwa khona: inhloko yendlela ejulile ehlathini, ikhona elithile lolwandle olukhulu, noma indawo yomhlangano edilini elikhulayo. Abathwebuli zithombe bamaka lapho kuthathwe khona isithombe, abaqwali bamaka ingqungquthela abazobuyela kuyo, futhi abashayeli balondoloza indawo yokupaka abangeke bayithole endaweni egcwele abantu.

Baphinde banqamule imingcele ngokukhululeka. I-coordinate pair isho into efanayo kuwo wonke amazwe nakuzo zonke izilimi, ukuze ukwazi ukwabelana ngendawo nomuntu othile phesheya futhi wazi ukuthi bazofika endaweni efanayo ncamashi. Lokho kuhlanganisa yonke indawo yikho okwenza izixhumanisi ze-GPS zibe yindlela enokwethenjelwa yokuchaza noma iyiphi indawo eMhlabeni.

Bona futhi Local Atual ukuthola indawo yakho yamanje kanye namathuluzi okusesha ikheli le-IP.
