I nobude kumephu: ukucacisa ngqo "Ikheli"

Njalo indawo eMhlabeni has "Ikheli" yayo ngokuthé ngqo, lapho ungathola ngokushesha. Akunzima njengoba kubonakala efika kuqala. I nobude kumephu zikuvumela ukuba ichaze indawo into ethile. Ukuze wenze lokhu, kumele ube ku-isandla ikhadi noma yesimanje GPS-Itilosi. Kuyini ezithakazelisayo, okufanayo kwendawo Ukudidiyela uhlelo esetshenziswa kwamanye amaplanethi.

Kungani nobude kukalwa ngama-degree

Cishe kakade ukuthi Earth uyindilinga. Uma ubheka umhlaba wonke, kungabonwa ukuthi bonke ubuso iplanethi yethu embozwe imigqa ezivamile - meridians futhi ukufana. izixhumanisi yabo, ngokulandelana, kukhona nobude kumephu, okuyinto kulinganiswa ngokwamazinga. Abantu abaningi abazi ngempela uqonde ukuthi kungani kwendawo kulinganiswa kuyinto ngokwamazinga. Nakuba-ke ulula, nje kudingeka ubambe ekhoneni. Ukuze wenze lokhu, ukucabanga iphuzu maphakathi Earth, kuzoba phezulu ekhoneni yethu. Enye uhlangothi ngizodabula nenkabazwe, lapho sihlukanisa iplanethi ngesigamu. Iqembu lesibili ngizodabula iphuzu ukuthi sidinga, makube edolobheni laseMoscow. Ngenxa yalokho, siye waphenduka ekhoneni. Ukuze sithole i-latitude, kubalulekile ukukala ngayo protractor. Kuvulwe degree angaba ngu-55, kanye inhloko-dolobha Russian Federation amanga enyakatho yenkabazwe, kubalulekile ukurekhoda umphumela kanje: 55 N (Ku-55 degrees enyakatho-latitude). Yokuthola i-longitude, kubalulekile ukudweba engela, beyizidalwa eziphakeme kunazo zonke neliyoba esikhungweni planethi. Kodwa ohlangothini olulodwa engela kufanele esekelwe Greenwich Meridian, kanti eyesibili - ukudabula besidinga iphuzu, kulesi simo, eMoscow. We ukuthola 37 degrees. Njengoba Umuzi uyizinhlangothi empumalanga umugqa owehlayo okuyi-prime, bhala umphumela olunembile - 37 E (37 degrees longitude empumalanga).

Ukunqunywa izixhumanisi kumephu

Lesi sibonelo wanikwa ukuze wenze kube lula ukuze uqonde ukuthi izixhumanisi kubalwa. Empeleni, konke kulula kakhulu, ngoba amabalazwe amaningi Globes usunayo i Igridi kwendawo. Degrees latitude aboniswa longitudes zazo wahlela parallel yenkabazwe. Meridians, kunalokho, kweqa yenkabazwe, zingasetshenziselwa ungakwazi ukuthola i-longitude. Okokuqala sidinga ukwazi lapho Nenkabazwe kuyadingeka kithi iphuzu: enyakatho noma eningizimu; ukuya ngasempumalanga noma ngasentshonalanga. I nobude kumephu kunqunywa igridi degree. Uma ubheka umhlaba wonke, kungabonwa ukuthi bonke meridians zinobude obulinganako, kuyilapho parallel - ezahlukene. Ukufana omude kunayo yonke ngokwaso yenkabazwe, ubude okuyinto cishe - km 40 000. I eduze Kuma-pole, ukufana abe mfushane. On the enyakatho nezingongolo eningizimu-latitude iphenduka ibe iphuzu nge izixhumanisi 90 ° N futhi 90 S Okumangazayo - kuphela kulezi zindawo ezimbili Emhlabeni akudingeki longitude.

Ukunquma ikuphi emkhathini izindlela zanamuhla

I-World Wide Web ungathola eziningi amabalazwe okuwusizo, ethandwa kakhulu okuyizinto Google maps futhi Yandex. I nobude kumephu kuchazwa nge okukodwa nje igundane. Futhi ubonisa izixhumanisi ngqo amamitha angu-10. Ngesandla Imiphumela enjalo kuphela azuzwe emabalazweni emikhulu. Enye ukucacisa latitude-longitude - GPS-Itilosi. Le divayisi ikuvumela ukuba uthole izixhumanisi ngqo, noma ngabe ukuphi. Umgomo we operation yayo kusekelwe yokwamukela amasignali kusuka iziphuphutheki. Futhi uyakwazi ukubonisa hhayi kuphela nobude, kodwa futhi engamamitha. amatilosi eziningi zanamuhla bayakwazi ukukhombisa indawo amamitha angu-2.
