Amamephu wewebhu avuselela umlando wokudwetshwa kwamabalazwe
Mhlawumbe asilokothi siphume ukubona imephu yomlando, ekhonjiwe ku-Google, ngakho-ke singakwazi ukuthi iminyaka ye-300 eyedlule yayisiphi izwe esimi namhlanje.
Ubuchwepheshe be-web mapping buvumele. Futhi wow! ngayiphi indlela
Isibonelo salokhu yibalazwe eliseLondon, lapho kungekhona kuphela abashicilele i-1746 cartography, kodwa futhi bazise indlela abaye bayilandela ukuze bayilungiselele emabalazweni wesigodla angaphezu kweminyaka engamashumi amabili.
Ngempela ngumsebenzi oyisibonelo, lapho amabalazwe wezinkathi phakathi kwe-1869 ne-1890 okungenzeka ukuthi yayisetshenziswe iphepha, ekhishwe ngokucophelela ukuze alondoloze izinga lemininingwane eyayiyinto yobuciko ngaleso sikhathi.
Ngenxa yalokho, kungenzeka ukuthi wenze izinto ezinjengalezi. Kuyathakazelisa ukuthi kuphi i-nucleus yasemadolobheni manje ilanga linye laliyizimboni ezichazwe ngokucacile emidwebo yokudweba.
Ukuze uhlanganise lo msebenzi, ngemuva kokuskena, kwakudingeka benze umsebenzi wokuhlanganisa lapho amaphutha amavamile avamile kushidi ngalinye, ekungeneni okungeke kwenzeke ukuthola. Akuyona into elula ukuyenza, kusukela isikhathi kubangela ukuthi amashidi aphephe, afakwe kulokho okwenzekayo lapho umsebenzi uhamba ngesithwebuli.
Bese benze iqoqo lamakhulu amaphuzu aziwayo ensimini, ahlukaniswe ngamamephu.
Ukusebenza inqwaba yamabalazwe endaweni enkulu, ephakanyiswe ngezindlela ezindala, idala izinkinga zokujikeleza, i-georeferencing, efana nokwehlisa ohlangothini olulodwa lenza omunye ahlehlise, ngisho naseshidi elifanayo.
Ngenxa yalokhu, baye benza ukukhonjwa kwemikhawulo yemigwaqo, ukuqedela i-topology yenethiwekhi okungahle kwenziwe ngayo isithombe esithombeni ngendlela ehlukile.
Ngakho-ke, usebenzisa indlela yokwenza isiphakamiso, lapho ulula, ibalazwe linikezwe eduze ngangokunokwenzeka njengokungathi limephu ekhonjiwe nge-ortho-referenced.
Inkinga ezithakazelisayo yizo zonke izindawo eziguqulwe, njengezindawo zokuqeqesha, lapho kungenakwenzeka ukunquma amaphuzu awaziwayo. Ngenxa yalokhu baye basebenzisa indlela enzima kakhulu yokuyiqonda ngokugcwele, okwenza izimbungulu ezivela emigwaqweni yomgwaqo, kucatshangelwa ama-gauges asetshenziswa ngaleso sikhathi. Futhi ngalokhu baye bazuza ushintsho olunembile nakakhulu.
Ekuphetheni, isibonelo esihle sokuthi yini engenziwa ngokusebenzisa amakhono wezobuchwepheshe nezobuchwepheshe atholakalayo. Futhi ukudabuka okukhulu kulabo abathumele egumbini elingaphansi lokugeza lawo mabalazwe akhuliswa ngezindlela zobuciko, kodwa ubunani babo bomlando asikwazi ukuwazisa ... okwamanje.
Ngidinga ukwazi amasu amasha wokubukwa kwamamephu.
