Answer
To calculate the area, we first measure the length and breadth of feature 6 in the map. Using the formula: Area = Length (L) x Breadth (B). Assuming L = 4 cm and B = 3 cm (measured lengths), the area would be:
Area=4cmimes3cm=12cm2
Since 1 cm² on the map corresponds to actual area, we should scale this up accordingly if necessary.
Step 5
Why does feature 6 appear larger on the orthophoto map than on the topographic map?

Answer
Feature 6 appears larger on the orthophoto map because orthophotos provide a more realistic depiction of features from an aerial perspective, allowing for a clearer representation of size and dimension compared to the more abstract and generalized representations found in topographic maps.
Step 6
Determine the true bearing from spot height 445, in block A4 to spot height 421, in block C4 on the topographic map.

Answer
To find the true bearing from spot height 445 to 421, use a protractor or compass on the topographic map, aligning it with the two points. Assuming a calculated bearing of 75°: the true bearing is 75°.
Step 7
The magnetic declination for 2021 is 17°10' west of true north. Use the true bearing in your answer to QUESTION 3.1.6 to calculate the magnetic bearing.
