MAGNETIC BEARING 2.1 Magnetic bearing = Geographic bearing + Mag. declination Geographical bearing = 192° 192° Mean magnetic declination 25°29’ West of true North (2001). Mean annual change 9’ Westward. WN MN Magnetic declination for 2010: 25°29’W + 81’ W = 26°50’ W Magnetic bearing for 2010: 192° + 26°50’ W = 218°50’W

GRADIENT = 1:31,2 FORMULA: Gradient = VI (Difference in height) 2.2 FORMULA: Gradient = VI (Difference in height) HE (Distance) 120 145 VI 145m – 120m = 25m 7,8cm HE 7,8cm x 10 000 100 000 =780m Gradient = VI HE = 1:31,2 Range: 1:30,4 to 1:32,8 25 780 = 1 31,2

AREA Area = Length x Breadth FORMULA 3,6cm Distance x Scale 100 000 2.7 Area = Length x Breadth FORMULA 3,6cm Distance x Scale 100 000 = 3,6 x 50 000 = 1,8km LENGTH Distance x Scale 100 000 = 3,0 x 50 000 = 1,5km BREADTH 3cm Area = 1,8km x 1,5km = 2,7 km² Range: 2,7km² to 3,04km²
