THE HEIGHT OF AN OBJECT
You can measure or estimate the distance to the object on
the map under Point 10.
Multiply this distance by the factor indicated in column IV or
V (Table 2) (whichever is easier for you), referring to the
angle in column I measured with the clinometer (the
description in Point 9) .
The above mentioned example is based on an angle of 14 and a distance of 2000m.
2000m X 25％ column IV (Table 2)
OR 2000m X 1/4 column V (Table 2)=500m

HOW TO MEASURE THE ANGLE
Measure the right side of the object . Keeping in mind the value in degree that you defined ,slowly orientate the
compass towards the left side of the object.From the first value in degree deduct the second value you just defined .
The difference represent the value in degree of the angle between the left and right sides of the object.
N.B:Measure of the angle through the north .If the value 360°(north)come across the direct line on the Glow-in-the
