Xa siceba indlela yendiza yomsebenzi we-oblique photography , ukwenzela ukuqokelela ulwazi lokuthungwa kwesakhiwo kwindawo ekujoliswe kuyo, ngokuqhelekileyo kuyimfuneko ukwandisa indawo yendiza.
Kodwa oku kuya kukhokelela kwiifoto ezininzi esingazidingiyo kwaphela, kuba kwezo ndawo zindisiweyo zenqwelomoya, kukho idatha enye kuphela kwentlanu yelensi eya kwindawo yovavanyo esebenzayo .
Inani elikhulu leefoto ezingasebenziyo liya kubangela ukwanda kwenani lokugqibela ledatha, eya kunciphisa kakhulu ukusebenza kakuhle kokusetyenzwa kwedatha, kwaye inokubangela iimpazamo kwisibalo se-aerial triangulation (AT).
I-software yokucoca isibhakabhaka inokunciphisa ngempumelelo iifoto ezingasebenziyo nge-20% ~ 40%, ukunciphisa inani elipheleleyo leefoto malunga ne-30% kunye nokuphucula ukusebenza kakuhle kwedatha ngaphezu kwe-50%.
