Iphutha elilula uma kwakhiwa umshini wokudweba: Ukuhlukanisa kusuka emephini
Ngifuna ukunikezela lokhu okuthunyelwe kube yiphutha elilula kakhulu ukuqhuba, ikakhulukazi kumamephu ayi-1: 10,000 kanye ne-1: 1,000 asetshenziselwa izinjongo ze-cadastral ezithathwe kumhede eyi-1: 50,000.
Khumbula ukuthi kusithunyelwe kwangaphambilini sibone ukuthi kanjani yenza lo mesh, futhi ngaphambilini sibone ukuthi kanjani qala ukuqala uze ufike kumephu eyi-1: 1,000. Kepha iphutha elilula ukukholelwa ukuthi le mesh ingahlukaniswa ebalazweni, futhi lokhu akulungile. Ukudidiyela kufanele kukhiqizwe kusetshenziswa i-latitude nobude isikhathi ngasinye lapho sifuna ukudala i-mesh denser futhi uma singawuboni umphumela.
Uma lesi kuyisigaba sobude obungu-6 ° ngo-8 ° latitude, esihambisana nendawo engu-16, okwenza izixhumanisi ze-UTM kube lula futhi sikuthumele ku-AutoCAD. Ake sithi othile uhlanya acabange ukuthi le mesh ingasikwa ebalazweni:
Leyo ukwahlukanisa, ngaphandle kokubala imidwebo, ijika lizovuleka lize lifinyelele endaweni ephakathi lapho lizokhiqiza khona umehluko wamamitha ayi-2,318.63 we-latitude.
Lapho wenza ukwahlukanisa okulandelayo, kuzokwenziwa iphutha elifanayo, kepha lizoncishiswa ngokulandelayo:
1: 1,000 (6th): akukho ukwahlukanisa
Kusukela ku-1: 500,000 (3): 2,318.63
Kusukela ku-1: 250,000 (1 ° 30'): 579.76
Kusukela ku-1: 100,000 (30´): 129.00
Kusukela ku-1: 50,000 (15´): 16.13
Amanani aphakathi kokuhlukaniswa nalawo asemuva kwawo, ngakho-ke kuya ngokuthi ahlukanisa kangaki, aqeda umphumela wokugcina ogcina eyinhlekelele ephelele uma umdwebi omuhle wemoto ebukeza umsebenzi.
Siyabona futhi ukuthi uma sahlukanisa ishidi elingu-50,000 10,000 ukuze sisuse i-16 mesh kulokhu, sizoba nephutha endaweni ephakathi nendawo efinyelela kumamitha ayi-XNUMX ukuthi ngenhlolovo ye-cadastral yasemadolobheni ingaba yimbi kakhulu futhi ibe yimbi kakhulu uma ingekho iyunifomu ngoba lokho kuyiphutha elisenkabeni ephakathi .
Noma ekuhlukaniselweni okungu-10,000 ibanga lincane impela ngakho-ke umkhuba wokuhlukanisa leli phepha emephini uvame kakhulu ... inqobo nje uma ungagwenywa kuzoba ngcono.
Inkinga eyodwa yilapho ufuna ukukhipha igridi ngamanani okuhamba nobude njengoba sibonile lokhu okuthunyelweNgezinhloso zokuphrinta, kepha inkinga ebucayi kakhulu ukuthi nini kanye nokuhlanjalazwa (okufana neNAD27 kuya kuNAD83) ngohlelo olwenzelwe izinhloso ezinjalo, lokhu kuzokhiqiza amaphutha we-splice azokwenza ukuhlukunyezwa kokuhlanzwa kwendawo.
