I-Latitude kanye ne-Longitude

I-Latitude kanye ne-longitude zakha igridi ehlanganisa yonke iplanethi, okusivumela ukuthi sichaze noma iyiphi indawo ngezinombolo ezimbili nje. Iwuhlelo oseluqondise amatilosi, abashayeli bezindiza, abahloli bamazwe, nabahambi bansuku zonke amakhulu eminyaka, futhi namuhla lunika amandla yonke imephu ye-smartphone nohlelo lokusebenza lokuzulazula olusebenzisayo. Uma usuqonda ukuthi amanani amabili asebenza kanjani ndawonye, ​​ukufunda izixhumanisi noma yikuphi emhlabeni kuba yimvelo yesibili.

Ubuhle balesi simiso ukutholakala kwayo yonke indawo. Ipheya elididiyelwe lisho into efanayo kuwo wonke amazwe nakuzo zonke izilimi, yingakho lihlala liwumgogodla wokuklanywa kwemephu yesimanje kanye nokwabelana ngendawo. Azikho izinguqulo ongazikhathaza ngakho futhi azikho izivumelwano zasendaweni okufanele uzifunde - izinombolo ezimbili kuphela ezikhomba endaweni eyodwa ncamashi eMhlabeni.

Iyini i-Latitude?

I-Latitude imigqa ihamba ngokuvundlile (empumalanga-ntshonalanga) futhi ikala ibanga enyakatho noma eningizimu yenkabazwe. Inkabazwe ingu-0°, iNorth Pole ingu +90°, kanti iSouth Pole ingu-−90°. Le migqa ibizwa nangokuthi i-parallels ngoba igijima ngokuhambisana futhi ayihlangani. Idigri ngayinye ye-latitude imele cishe amakhilomitha angu-111 emhlabeni, ngakho i-latitude ikunikeza umuzwa osheshayo wokuthi indawo ihlala kude kangakanani enyakatho noma eningizimu.

Iyini I-Longitude?

Imigqa Yobude igijima iqonde (inyakatho–eningizimu) futhi ikala ibanga empumalanga noma entshonalanga ye-prime meridian e-Greenwich, e-London. Amanani asukela ku-0° ukuya ku-+180° empumalanga futhi −180° entshonalanga. Le migqa yaziwa ngokuthi ama-meridians, futhi ngokungafani nokufana ayahlangana ezigxotsheni. Ngenxa yokuthi umhlaba uyazungeza, i-longitude nayo isondelene nezindawo zesikhathi - njalo ngo-15° welongitude ihambisana cishe nehora elilodwa lomehluko wesikhathi.

Ukufunda I-Coordinate Pair

Izixhumanisi zihlala zibhalwa nge-latitude kuqala, bese i-longitude — isibonelo 51.5074, -0.1278 yi-London. I-latitude eqondile isenyakatho, i-negetive iseningizimu; i-positive longitude isempumalanga, inegethivu iyintshonalanga. Ukuthola i-oda ngendlela efanele: ukushintsha izinombolo ezimbili kungakubeka ku-hemisphere engalungile ngokuphelele.

• Amadigri edesimali: 40.7128, -74.0060 (ihlangene futhi ilungele uhlelo lokusebenza).
• Amadigri-amaminithi-amasekhondi: 40°42'46"N 74°00'22"W (ivamile kumashadi).
• Uphawu ngokumelene nohlamvu: i-longitude eyinegethivu kanye no-"W" asho into efanayo.

Amadigri, Amaminithi, namasekhondi

Inothi ye-DMS endala ihlukanisa idigri ngayinye ibe yimizuzu engama-60, futhi umzuzu ngamunye ube imizuzwana engama-60, njengewashi. Lokhu kungase kuzwakale kumnandi ekuqaleni, kodwa kumephu ngobunono kumadigri wedesimali. Nansi indlela yokucabanga mayelana nokuhlukaniswa:

1. Idigri iyiyunithi enkulu kunazo zonke futhi ifaka ibhande elibanzi lomhlaba.
2. Iminithi ingxenye eyodwa kweziyisithupha zedigri, cishe amakhilomitha angu-1.85 we-latitude.
3. Isekhondi ingxenye eyodwa kweziyisithupha zomzuzu, cishe ngamamitha angu-31 — ukunemba ngokwanele kwesakhiwo.

Izinhlelo zokusebenza eziningi zikhetha amadigri edesimali namuhla, kodwa amashadi e-nautical, indiza, nokuhlola kusancike ku-DMS, ngakho kuyakhokha ukukubona kokubili.

Okwenza Kubaluleke Ekuphileni Kwansuku Zonke

Uthembele kububanzi nakubude kaningi kakhulu kunalokho ongase ukucabange. Izinhlelo zokusebenza zokugibela zikhomba indawo ozoyithatha, izinsiza zokulethwa zithola umnyango wakho, izibikezelo zesimo sezulu zifika endaweni yakho ngqo, futhi izithombe ezithathwe ocingweni lwakho zimakwa buthule ngamazixhumanisi. Ukuqonda izinombolo ezingemuva kwalezi zici kukusiza ukuthi uxazulule inkinga lapho imephu ikuthumela endaweni engafanele futhi ikuvumela ukuthi wabelane ngezindawo ngokuzethemba.

Yibone Ngezenzo

Vula isitholi sezixhumanisi ze-GPS bese uchofoza imephu ukuze ubuke i-latitude nobude ibuyekeza bukhoma njengoba uhambisa iphinikhodi. Kuyindlela eshesha kakhulu yokwakha intuition yokuthi igridi isebenza kanjani. Uma usulungile, thola izixhumanisi zakho manje futhi ubone kahle ukuthi umi kuphi kugridi yomhlaba.

imibuzo ejwayelekile ukubuzwa

Yikuphi okuza kuqala, i-latitude noma i-longitude?

I-latitude ihlale ibhalwa kuqala, i-longitude yesibili. Leli oda liwumhlangano womhlaba wonke, futhi ukulilandela kuqinisekisa ukuthi izixhumanisi zakho zikhomba endaweni ehlosiwe kunesibuko salo endaweni ehlukile.

Zisho ukuthini izimpawu ezinhle nezingezinhle?

Ilathithudi ephozithivu isenyakatho nenkabazwe futhi enegethivu iseningizimu. Ilongitudi ephozithivu isempumalanga ye-prime meridian futhi enegethivu isentshonalanga. Izimpawu zithatha indawo yezinhlamvu ezingu-N, S, E, kanye no-W.

Iqhelelene kangakanani idigri eyodwa ye-latitude?

Cishe amakhilomitha angu-111, futhi lokhu kuhlala kuvumelana yonke indawo. Amadigri e-Longitude, ngokuphambene, ashwabana abheke ezigxotsheni ngenxa yokuthi ama-meridians ayahlangana, ngakho ukukhala kwawo emhlabeni wangempela kuncike ekutheni ukude kangakanani enyakatho noma eningizimu.

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