Solution
1.1
The contour interval is the difference in elevation between adjacent contour lines. Typical medium-scale topographic maps often use intervals like \(20\,m\).
Answer: **C**
1.2
A scale written as \(1:50000\) is a representative fraction, which shows that one unit on the map equals \(50000\) of the same units on the ground. This is known as a ratio scale.
Answer: **A**
1.3
The designation “N 17” indicates a route labelled with “N” which usually stands for a National route.
Answer: **D**
1.4
Based on the context from the orthophoto, the type of farming taking place in Block C2 is identified as crop farming.
Answer: **C**

The contour interval of a topographic map is crucial for understanding the elevation changes across the landscape. Typically, if you're seeing subtle curves on the map, a common interval might be around 20 meters, as it provides a reasonable balance of detail without overwhelming the reader. When interpreting scales, the ratio scale like 1:50000 indicates that one unit on the map represents 50000 units in reality, making it essential for accurate spatial understanding. It's a straightforward way to quantify distance and ensures that you can visualize the terrain effectively!
