Practical Geography

A wildlife sanctuary covers an area of $24\text{ cm}^2$ on Map P, which is drawn to a scale of $1 : 60,000$. If Map P is enlarged to produce Map Q with a scale of $1 : 20,000$, what is the area of the sanctuary on Map Q in $\text{cm}^2$?

Arrange the following sequential steps involved in conducting a chain survey fieldwork operation in the correct chronological order from start to finish.

A hydrologist conducts a morphometric analysis on a river basin using a topographic map drawn at a scale of $1:25,000$. Stream ordering reveals $28$ first-order streams, $7$ second-order streams, and $1$ third-order stream. If the total basin area measured on the map is $32\text{ cm}^2$, what is the stream frequency ($F_s$) of the basin in $\text{streams per km}^2$?

During elementary fieldwork, a geography student needs to mark intermediate stations along a baseline to ensure a perfectly straight line over long distances. Which surveying instrument is designed for maintaining this straight alignment?

During a chain survey fieldwork operation, why is the double-line method standard practice for recording entries in a field book?

During a fieldwork measurement along a baseline, a geography student uses a steel tape with a nominal length of $30.00\text{ m}$. Due to high ambient temperature, the actual length of the tape has expanded to $30.15\text{ m}$. If the uncorrected recorded distance for the baseline is $450.00\text{ m}$, what is the true ground distance and the nature of the measurement error?

A cartographer constructs a quantitative dot map to represent the distribution of livestock across a region. On the map, a total of $64$ dots represent a total population of $160,000$ sheep. If Province X has a sheep population of $35,000$, how many dots should be plotted to represent Province X on this map?

An aerial reconnaissance map of a catchment area displays primary tributaries flowing parallel to each other in elongated valleys, with short secondary streams joining them almost at right angles along structural strike lines of tilted, alternating hard and soft rock strata. Which drainage pattern is depicted, and what main geological control governs its formation?

On a topographical map drawn at a scale of $1 : 100,000$, a communications mast is positioned at point X with an elevation of $180\text{ m}$, while a valley lookout at point Y has an elevation of $420\text{ m}$. If the terrain between these two points maintains a constant gradient of $1 \text{ in } 25$, what is the straight-line distance between point X and point Y on the map?

Relate each statistical mapping technique on the left to its governing cartographic principle or inherent analytical limitation on the right.

During a field survey across undulating terrain, a surveyor must determine the vertical angle of inclination of a hillside to calculate the horizontal distance between two stations. Which of the following instruments is designed specifically for measuring this slope angle?

On a topographical map representing a mountainous terrain, a lower index contour line is marked at $500\text{ m}$ above sea level and a higher index contour line is marked at $900\text{ m}$ above sea level. If there are $4$ equal contour intervals between these two index contours, what is the elevation in metres of the third contour line above the $500\text{ m}$ index contour?

In satellite remote sensing, sensor performance and data utility are defined by distinct resolution dimensions. Match each resolution type on the left with its correct definition on the right.

On a regional planning map drawn to a Representative Fraction (R.F.) scale of $1 : 80,000$, a proposed bypass road between two industrial hubs measures $16.5\text{ cm}$. What is the actual ground distance of the bypass road in kilometers?

Match each elementary surveying instrument listed on the left with its primary fieldwork function on the right.

An environmental planning team in Nigeria is integrating multispectral satellite imagery with ground survey data in a Geographic Information System (GIS) to monitor vegetation health across the Guinea Savanna belt. When analyzing the reflectance values of healthy green crops, the sensor records high reflectance in the near-infrared (NIR) spectrum and high absorption in the red visible spectrum. Which fundamental remote sensing principle explains this specific spectral reflectance behavior?

On a topographical map extract drawn at a scale of $1:50,000$, the total length of all stream channels within a river basin is measured as $18\text{ cm}$, while the total area of the basin on the map is $12\text{ cm}^2$. What is the drainage density of this river basin in $\text{km/km}^2$?

Match each statistical mapping technique listed on the left with the specific spatial phenomenon or cartographic data representation it is best suited to display on the right.

A field surveyor needs to determine the horizontal distance between two stations located on steeply sloping ground using a steel measuring tape and a plumb bob via the direct stepping method. Arrange the following field procedure steps in the correct chronological order from start to finish.

A proposed industrial estate is represented as a square measuring $6\text{ cm}$ by $6\text{ cm}$ on a topographical map drawn to a scale of $1 : 40,000$. If the map is reduced to a scale of $1 : 120,000$, what is the new area of the industrial estate on the reduced map?
