QUESTION 2: MAP CALCULATIONS AND TECHNIQUES
2.1 The orthophoto is referenced from the topographic map 2527CA 20 RUSTENBURG.
State what the following indicate in the index to sheet on the orthophoto map. 2.1.1
2.2 Calculate the magnetic bearing of spot height 1191 (block B7) from the trigonometrical station 29 (block B7) for the year 2019. Show ALL calculations. Marks will be awarded for calculations.
Formula: Magnetic bearing = True Bearing + Magnetic Declination (7 x 1) (7)
2.3 Refer to the blocks F2 and E4 on the topographic map.
2.3.1 Calculate the average gradient of the N4 road between G (block F2) and H (block E4) on the topographic map. Show ALL calculations. Marks will be awarded for calculations.
Formula: Gradient = Vertical Interval (VL) (5 x 1) (5)
Horizontal Equivalent (H.E)
2.3.2 Interpret the gradient calculated in QUESTION 2.3.1. (2 x 1) (2)
2.3.3 Is G visible from H? Give a reason for your answer.
2.4 Write the scale of the topographic map as a word scale. (1 x 1) (1) [20]
QUESTION 3: APPLICATION AND INTERPRETATION
3.1 Refer to the Dorpspruit River on the topographic and orthophoto maps to answer the questions below.
3.1.1 In which general direction is the Dorpspruit River flowing? Give TWO topographic or orthophoto evidence to support your answer.
3.1.2 Is the Dorpspruit River between points 14 and 15 on the orthophoto map in the youth stage or mature stage? Give TWO orthophoto evidences to motivate your answer.
3.2 The stadium numbered 1 on the orthophoto map has a good location. Provide TWO pieces of topographic and orthophoto evidence to support this statement. (2 x 2) (4)
3.3 Locate R (block H9) on the topographic map.
3.3.1 Identify the dominant street pattern within the vicinity of R. (1 x 1) (1)
3.3.2 Give ONE map evidence why the street pattern identified in QUESTION 3.3.1, was developed. Reason: (1 x 2) (2)
3.3.3 Why is the street pattern identified in QUESTION 3.3.1 not preferred by modern town planners? Reasons: (2 x 2) (4)
3.4 Find settlement S (block H1) on the topographic map.
3.4.1 Would you describe settlement S as a dry point or wet point settlement? Answer: (1 x 1) (1)
3.4.2 Explain your answer to QUESTION 3.4.1. (1 x 2) (2)
3.5 Generally, Rustenburg experiences relatively cool summers than expected. Give a reason for that. Answer: (1 x 1) (1) [25]
QUESTION 4: GEOGRAPHICAL INFORMATION SYSTEMS (GIS)
4.1 Provide a GIS concept for the following descriptions.
4.1.1 Data that can be linked to locations in geographical space, usually via features on the map.
4.1.2 A question, especially if asked to a database by the user via database management systems.
4.1.3 A map designed to show a single spatial distribution pattern, using a specific map type.
4.1.4 Characteristic of a feature that contains measurements of value for feature and is displayed as columns in table form.
4.1.5 The combination of two or more data layers to create a new one. (5 x 1) (5)
4.2 Refer to block J3 on the topographic map.
