Step 2
4.1.2 Explain the relevance of using vector data on the topographic map.
Answer
Using vector data on the topographic map is significant for various reasons. Firstly, it standardizes data, allowing users to easily reference features on the map, such as roads and rivers. Vector data represents spatial features more clearly, making the interpretation of geographic details user-friendly. Moreover, it enables quicker data visualization, allowing users to obtain information at a glance. Lastly, vector data provides accurate representations of shapes and distances of spatial features, improving navigational accuracy.

4.2.2 Explain the relevance of scale when facing a geographical query/problem, e.g., a possible veld fire in block D8 on the topographic map.
Answer
The relevance of scale in geographical queries, such as assessing a veld fire in block D8, is crucial. A larger scale provides more detail, enabling accurate positioning of the fire, determining the distance from water sources, and planning evacuation routes. This helps in making informed decisions for emergency responses.
Step 5
4.2.3 How can the scale of the topographic map and orthophoto map be manipulated in order to make data integration of these two maps easier?
Answer
To facilitate data integration, the scale of the topographic map can be adjusted to enlarge it or reduce the scale of the orthophoto map to a common scale, ensuring both maps align for accurate analysis.

4.3.4 Explain why it is important for the well-being of the community of Pietermaritzburg to analyse these statistics.
Answer
Analyzing these statistics is important for various reasons. It helps identify the frequency of crime, which enables law enforcement to deploy resources effectively. Understanding crime patterns assists in developing strategies for community safety, such as neighborhood watch programs. Moreover, accurate statistics can improve insurance policy validation and help citizens adapt their safety measures to emerging threats, ultimately enhancing community well-being.
