Answer
Verskynsel 6 is groter op die ortofotokaar omdat die ortofotokaar in 'n hoër resolusie verteenwoordig word, wat lei tot 'n groter visuele voordrag van die area.

Answer
Die magnetiese peiling (MP) kan bereken word as:
MP=WP+MD
waar WP die ware peiling is, wat 207°10' is, en MD die magnetiese deklinasie is, wat 17°10' is. Dus, MP = 207°10' + 17°10' = 224°20'.
