Yiyiphi imilinganiselo yemidwebo?

Ngaphambi kokuba uqale ukuqwalasela umlinganiselo osemgangathweni wemidwebo, kufuneka uqonde ukuba yintoni le nto ingqiqo. Ngoko, ixabiso elifanayo likwimeko epheleleyo ulwalamano lweendlela ezimbini. Nangona kunjalo, ukutolika kwalolu ngcaciso kukwaziwa ngokubanzi, njengomlinganiselo wobukhulu bokudweba kumlinganiselo wenjongo yangempela. Ngako oko, kunokuthi kucingelwe ukuba isigama esichazwe apha ngasentla sifumane isicelo esiphezulu kwimifanekiso ye-cartography, i-geodesy kunye nenjongo yokuyila.

Kutheni kubalulekile?

Njengoko sele kukhankanywe ngaphambili, izinto zangempela zinokubakho ubuncinane obukhulu ngokwaneleyo, kwaye zincinci kakhulu. Nangona kunjalo, umntu akakwazi ukukhangela zonke izinto ngobukhulu obukhulu, kuba ishidi lamanqaku amakhulu afunekayo kwiphepha lephepha lokwakheka kwesakhiwo , kwaye ke, i-high degree of details iyakufuneka ukuba iphinde iphinde iphinde iphinde ilandele izinto ezincinci (njengokomzekelo, kwi-clockwork). Ngenxa yoko, umntu ulungele ukumela izinto eziyimfuneko eziye zancitshiswa (okanye zandisiwe) kwinani elithile lexesha lokuba lula ukuqonda kunye nokuthiwa "ukufundeka" komfanekiso. Okwangoku, imilinganiselo ethile isebenza, umzekelo, i-GOST "Isilinganiselo semidwebo", echaza yonke imfuno yefom nokugcwalisa imifanekiso efanelekileyo.

Izinto ezinkulu

Njengoko kushiwo ngaphambili, ukuboniswa kwezakhiwo nezinye izinto ezinkulu kuyimfuneko ukusebenzisa umlinganiselo wemidwebo yento ebizwa ngokuthi ukunciphisa. Ziyafana, oku kuthetha ukuba isampula engabonakaliyo ayiyi kusebenza. Iimpawu eziqhelekileyo zi: 1: 2; 2.5; 4; 5; 10; 15; 20; 25; 40; 50; 75; 100; 200; 400; 500; 800; 1000. Cinga oko kuthetha ukuthatha uhlobo olufanayo. Ngoko, okwenene (ngamanye amazwi, imvelo) imvulophu yento ichazwe ngendlela yobhaliso 1: 1. Ngoko ke, njengoko umlinganiselo wemidwebo unciphisa, ubukhulu bokuqala (1) buchazwe kuqala, kwaye ngoko inani elibonisa ukuba kaninzi kangakanani umzobo uyancitshiswa malunga Ukulinganisa okwenene. Ukwakhiwa, ngaphezu kweirekhodi eziqhelekileyo ezingentla, izikhombisi-1: 2000 zingasetyenziswa kwakhona; 5000; 10,000; 20,000; 25,000; 50 000.

Iinkcukacha ezincinci

Kwimeko apho ufuna ukubonisa izinto ezincinci kumzobo, umlinganiselo wemidwebo yokwandisa isetyenziswa ngokuqhelekileyo. Kule meko, ayikho into ehlukeneyo yamanani, kodwa umgangatho uchaza ixabiso eliqhelekileyo elisetyenziswayo. Ngoko, uchungechunge lwemodeli lubonakala kanje: 2; 2.5; 4; 5; 10; 20; 40; 50; I-100: 1. Ukuchongwa kweemibhalo ezifanayo zifunda ngale ndlela: kuqala inombolo ebonisa ukuba kaninzi kangakanani umfanekiso kumzobo ukwanda ngokuthelekiswa nento yokuqala. Inombolo yesibini emva kokuba ikholoni ibonakalisa okwenene (yendalo okanye yinyani) ubungakanani bento ekubhekiselwe kuyo (kuthathwa njengokuba 1).

Isiphelo

Kulo phepha, umlinganiselo wemidwebo kunye neenkalo zazo eziqhelekileyo zacatshangelwa. Kufuneka kwakhona kuqaphele ukuba kwiiplani, iiprojekthi kunye nemifanekiso ngokwabo, ubukhulu bezinga liboniswe kwikholam ekhethiweyo ngokukhethekileyo kwisakhelo, mhlawumbi eyaziwa njengesitampu.
