Indlela Yokufunda Ishadi Lolwandle Lwabasolwandle
Amashadi olwandle angenye yamathuluzi abaluleke kakhulu okuhamba ngomkhumbi kumatilosi. Ukuwasebenzisa kahle kungasiza ukugcina umkhumbi wakho ungangeni engozini futhi kuqinisekise uhambo oluphephile nolusebenzayo. Kulesi sihloko, sizoxoxa ngendlela yokufunda ishadi lolwandle ngokuningiliziwe, kusukela eziyisisekelo kuya kumasu athuthukile. Ake siqale ngokuqonda ukuthi ayini amashadi olwandle nokuthi kungani ebalulekile.
Iyini Ishadi Lolwandle?
Ishadi lolwandle liwumfanekiso ocacile wezindawo zolwandle nolwandle ohlanganisa ulwazi olubalulekile oluhlukahlukene njengokujula kwamanzi, imingcele yolwandle, izindawo eziphansi kwe-buoy, izibani zokukhanyisa, imizila yokuthumela imikhumbi ephakanyisiwe, kanye nezingozi ezahlukahlukene ezingase zihlangane nazo olwandle njengemifula yamakhorali, ukuphahlazeka kwemikhumbi, njalo njalo. Amashadi olwandle ngokuvamile asetshenziswa ngendlela ebonakalayo (ephepheni) noma yedijithali ngohlelo lwe-ECDIS (Electronic Chart Display and Information System).
Umlando Omfushane Wezishadi Zolwandle
Amashadi olwandle aqala ukusetshenziswa amaFenike ezikhathini zasendulo, kodwa izinhlobo zamamephu zesimanje zaqala ukuthuthuka ngekhulu le-13 nele-14 ngabasolwandle baseYurophu. Kusukela ngaleso sikhathi, amashadi olwandle aye aqhubeka nokukhula kanye nentuthuko kwezobuchwepheshe kanye nolwazi lokuhamba.
Izingxenye Zeshadi Lolwandle
Ukuze uqonde ishadi lolwandle, kufanele ujwayelane nezinto ezahlukahlukene eziqukethwe kumephu:
1. Isihloko Nenombolo Yemephu
– Ishadi ngalinye lolwandle livame ukuba nesihloko esinikeza ulwazi oluyisisekelo mayelana nendawo ehlanganisiwe kanye nenombolo yeshadi ukuze kube lula ukulibona.
2. Isikali Semephu
– Isikali semephu sibonisa ubudlelwano phakathi kwebanga elikumephu nebanga langempela olwandle. Isibonelo, isikali esingu-1:50.000 sisho ukuthi iyunithi eli-1 kumephu lilingana namayunithi angu-50.000 emhlabeni wangempela.
3. I-Compass Rose
– Ikhampasi i-rose noma ikhampasi yomoya ikhombisa inyakatho yangempela, okusiza ekuqondeni. Amanye amamephu abonisa nokwehluka kwamagnetic endawo.
4. I-Latitude kanye ne-Longitude
– I-Latitude kanye ne-longitude kusiza ekunqumeni indawo ngokunembile.
5. Ukujula (Imisindo)
– Amashadi olwandle abonisa ukujula kwamanzi okulinganiswe ngamamitha, ngezinyawo, noma ngama-fathom. Lolu lwazi lubalulekile ekugwemeni amatshe noma ulwandle olungajulile.
6. Izimpawu kanye nezifinyezo
– Amashadi olwandle agcwele izimpawu nezifinyezo ezahlukene ezimele ama-buoy, izibani, izinhlobo zezindawo ezingaphansi kolwandle, kanye nezingozi zokuzulazula.
Izinyathelo Zokufunda Imephu Yolwandle
1. Khomba Indawo
Isinyathelo sokuqala ukuhlonza indawo ebalazweni ofuna ukuyifunda. Bheka isihloko sendawo kanye nemingcele ukuqinisekisa ukuthi ubuka imephu efanele.
2. Yazi Isikali Semephu
Qonda isikali semephu ukuze uqonde izilinganiso zamabanga asetshenzisiwe. Lesi sikali sivame ukuboniswa phansi noma ekhoneni lemephu. Qiniseka ukuthi uyayifunda futhi uyayiqonda inganekwane, evame ukuchaza izimpawu nezifinyezo ezisetshenzisiwe.
3. Sebenzisa i-Compass Rose
Sebenzisa i-compass rose ukuze ubone enyakatho. Lokhu kuzokusiza ukuthi ubone ukuthi umkhumbi uqonde kuphi nokuthi uyaphi.
4. Thola Indawo Yendawo
Sebenzisa i-latitude kanye ne-longitude ukuze unqume indawo yakho yezwe. Ungasebenzisa i-GPS ukuthola ama-coordinates anembile bese uwafanisa neshadi lolwandle.
5. Hlola Ukujula
Hlola ukufundwa kokujula endaweni ohlela ukuyihamba. Ukujula ngaphansi kobuso bamanzi kuvame ukuboniswa izinombolo ezinobukhulu obuhlukene kanye nezimpawu ezibonisa amayunithi okulinganisa.
6. Ukuhlonza Umzila
Khomba indlela ozoyithatha. Bheka izindawo ezibalulekile zokuhamba njengezindawo zokubhukuda, izibani zokukhanyisa, nezinye izindawo ezingasetshenziswa njengezindawo zokubhekisela kuzo.
7. Qaphela Ingozi
Hlola njalo izimpawu ezibonisa izingozi zokuhamba njengemifula, izingozi, noma imisinga enamandla. Lolu lwazi lubalulekile ekugwemeni izingozi.
Amasu Athuthukile Ekufundeni Amashadi Olwandle
1. Ukusebenzisa i-Radar ne-Sonar
Ngaphezu kwamashadi olwandle, i-radar ne-sonar kungamathuluzi obuchwepheshe obuphezulu asiza amatilosi ekuzulazuleni. I-radar ingasiza ekuboneni eminye imikhumbi nezinto ezinkulu ebusweni, kuyilapho i-sonar iwusizo kakhulu ekulinganiseni ukujula nasekutholeni izinto ezingaphansi komhlaba.
2. Ukuhlela Umzila Ngamathuluzi E-elekthronikhi
Ngohlelo lwe-ECDIS, amatilosi angahlela imizila ngokushesha nangokunembile. Kodwa-ke, amatilosi asadinga ukuqonda izisekelo zokufunda amashadi olwandle asetshenziswa ngesandla uma kwenzeka uhlelo lwe-elekthronikhi lungasebenzi kahle.
3. Landela Ulwazi Lwesimo Sezulu
Izimo zezulu zithinta kakhulu ukuhamba kwemikhumbi. Ukulandela izibuyekezo zesimo sezulu nokuhlola ukuthi lezi zimo zingathinta kanjani umzila wasolwandle ohanjwayo kubalulekile ukuze kuphephe.
Amathiphu Namaqhinga Okufunda Amashadi Olwandle
1. Ukuzijwayeza Ukufunda Imephu
– Njenganoma yiliphi ikhono, ukuzijwayeza kuyadingeka ukuze ube nekhono lokufunda amashadi olwandle. Zama ukuzibandakanya ekulingiseni okuhlukahlukene kokuhamba ngomkhumbi.
2. Iziqondiso Zokufunda Nezincwadi
– Izincwadi eziningi neziqondiso zinikeza ulwazi oluningiliziwe ngokufunda amashadi olwandle. Funda futhi usebenzise lezi zinsiza ukuze ujulise ulwazi lwakho.
3. Buza futhi Ubonisane
– Unganqikazi ukubuza amatilosi anolwazi oluthe xaxa noma uxhumane nomqeqeshi wezokuhamba ukuze uthole ulwazi olwengeziwe.
4. Buyekeza Njalo Imephu
– Qiniseka ukuthi usebenzisa amashadi akamuva olwandle, njengoba kunezikhathi lapho izinguquko olwandle zingabhalwa khona kumashadi amadala.
Isiphetho
Ukufunda ishadi kuyikhono elibalulekile wonke amatilosi okumele alifunde. Kusukela ekuqondeni izimpawu nezifinyezo, ekunqumeni isikali, kuya ekulinganiseni ukujula, zonke izici zidlala indima ebalulekile ekuqinisekiseni uhambo oluphephile nolusebenzayo. Ngokuzijwayeza njalo nokuhlala usesikhathini ngentuthuko yakamuva kwezobuchwepheshe bokuzulazula, amatilosi angagcina la makhono ebukhali futhi efanele, okuwavumela ukuthi abhekane nezinselele olwandle ngokuzethemba okukhulu nangokulungela.
Ukuzulazula akukhona nje ukufika lapho uya khona, kumayelana nokuhamba okuphephile. Ngethemba ukuthi lo mhlahlandlela uzokusiza ukuthi uqonde kangcono ukuthi ungayifunda kanjani ishadi lolwandle futhi wenze uhambo lwakho luphumelele futhi luphephe kakhudlwana!
