Iphutha elula xa kwakhiwa isitayela se-cartographic: Ukwahlula kwimephu

Ke ndiyazingcwalisa le posi impazamo Kulula kakhulu ukuba ukuziqhelanisa, isikakhulu iimephu 1: 10,000 1 and: 1,000 esetyenziselwa iinjongo cadastral uzakususwa 1 enemingxuma: 50,000.

Khumbula ukuba kwisithuba sangaphambili sibone indlela ukudala le mesh, kwaye kwangaphambili sibone indlela qalisa ude ufike kwimephu eyi-1: 1,000 XNUMX. Kodwa eyona mpazamo ilula kukukholelwa ukuba lo mesh unokwaphuka kwimephu, kwaye oku akulunganga. Ukulungelelaniswa kufuneka kuveliswe kusetyenziswa ubude kunye nobude ngalo lonke ixesha sifuna ukwenza i-denser mesh kwaye ukuba asiziboni iziphumo.

Ukuba eli licandelo le-6 ° ubude nge-8 ° latitude, ehambelana nendawo ye-16, ukuvelisa ulungelelwaniso lwe-UTM kulula kwaye kuyithumela kwi-AutoCAD. Masithi umntu uyaphambana ukucinga ukuba lo mnatha unganqunyulwa kwimephu:

indawo ye-utm 16

Loo mahlulo, ngaphandle kokubala i-midpoints, i-curve iya kuvulwa kuze kube yilapho ifikelele kwindawo ephambili apho yayiza kuvelisa umehluko weemitha ezili-2,318.63 ze-latitude.

indawo ye-utm 16

Xa wenza isahlulo esilandelayo, kuya kubangela impazamo efanayo, kodwa oko kuncitshiswe ngolu hlobo lulandelayo:

1: 1,000 (6 °): akukho sabelo

Ukwahlula omnye kwi-1: 500,000 (3 °): 2,318.63

Qala i-1: 250,000 (1 ° 30 '): 579.76

Ukwahlula omnye kwi-1: 100,000 (30 '): 129.00

Ukwahlula omnye kwi-1: 50,000 (15 '): 16.13

umfanekiso Iimpawu zentsulungeko aphakathi isahlulelo yaye ngoko nangoko, ngoko kuxhomekeke ushiya kangaphi oluhlala bawohloka isiphumo isiphelo ekugqibeleni ukuba intlekele ngokupheleleyo ukuba cartographer elungileyo kwakhona umsebenzi.

Kwakhona sibona ukuba ukuba nenxaxheba kuxwebhu 50,000 le ukususa 10,000 enemingxuma ukuba impazamo kwindawo engundoqo ye ukuya 16 iimitha uphando cadastral ezidolophini kungaba kubi nakakhulu ukuba uniform kakhulu ngenxa yokuba oko impazamo yokuba kugxininiswe . 

Nangona kukwahlukana kwe-10,000 umgama umncinci kakhulu ngoko ukuqhekeka kweli phepha kwimaphu kuqhelekileyo ... nje kuphela ukuba kunokukhutshwa kuya kuba ngcono.

Ingxaki xa ufuna ukuvelisa igridi kwiimigangatho kunye nobude obude njengoko sibonile kuyo esi sithubaNgeenjongo zokuprinta, kodwa eyona ngxaki inkulu kukuba nini kunye nokuchaswa (njenge-NAD27 ukuya kwi-NAD83) ngenkqubo eyenzelwe ezi njongo, oku kuyakuvelisa iimpazamo ze-splice eziza kwenza ukungcungcuthekiswa kokucocwa kwetopiki.
