An environmental management team in Nigeria is configuring a Geographic Information System (GIS) to analyze continuous geographical phenomena across a river basin, such as elevation gradients and soil moisture distribution. Which of the following GIS data models is most suitable for accurately representing these continuous spatial phenomena?

Cevabı ve açıklamayı göster

Cevap: The raster data model, because it represents continuous surface features through an array of grid cells, each storing a specific value.

Cevap

The raster data model is most suitable because it represents continuous surface features through an array of grid cells, each storing a specific attribute value.
The raster data model divides geographical space into a continuous grid of cells (pixels), where every cell stores a measurement representing phenomena that vary continuously across a surface, such as land elevation, temperature, or moisture levels.

Adım Adım Çözüm

1
Identify the nature of the spatial phenomena being modeled
Elevation gradients and soil moisture distribution vary smoothly across space without defined boundaries, making them continuous spatial phenomena.
Geographical data is categorized into discrete features (with clear boundaries) and continuous surfaces (changing seamlessly across space).
2
Select the GIS data structure optimized for continuous surface representation
The raster data structure represents space as a regular tessellation of grid cells or pixels, assigning a scalar value to every cell location.
Raster grids are mathematically and structurally ideal for continuous elevation models (DEMs), satellite imagery, and environmental gradients.

A forest reserve is represented as a rectangular feature measuring 8 cm8\text{ cm} by 10 cm10\text{ cm} on Map X, which is drawn to a scale of 1:50,0001 : 50,000. On a newly drawn map, Map Y, the same forest reserve occupies an area of 320 cm2320\text{ cm}^2. What is the representative fraction scale of Map Y?

Cevabı ve açıklamayı göster

Cevap: 1:25,0001 : 25,000

Cevap

The representative fraction scale of Map Y is 1:25,0001 : 25,000.
The original map area is 80 cm280\text{ cm}^2 and the enlarged area on Map Y is 320 cm2320\text{ cm}^2, giving an area scale factor of 44. Taking the square root gives a linear scale factor of 22. Dividing the original scale denominator of 50,00050,000 by 22 gives 25,00025,000, resulting in a scale of 1:25,0001 : 25,000.

Adım Adım Çözüm

1
Calculate the area of the forest reserve on Map X
Area on Map X=8 cm×10 cm=80 cm2\text{Area on Map X} = 8\text{ cm} \times 10\text{ cm} = 80\text{ cm}^2
Finding the initial area on the original map is required to determine the area enlargement ratio.
2
Calculate the area scale factor between Map X and Map Y
\text{Area Scale Factor} = \frac{\text{Area on Map Y}}{\text{Area on Map X}} = \frac{320\text{ cm}^2}{80\text{ cm}^2} = 4
The area scale factor indicates how many times larger the surface area appears on Map Y compared to Map X.
3
Determine the linear scale factor
\text{Linear Scale Factor} = \sqrt{\text{Area Scale Factor}} = \sqrt{4} = 2
Because surface area changes as the square of linear dimensions (n2n^2), the linear scale factor nn is the square root of the area factor.
4
Calculate the new representative fraction scale for Map Y
\text{New Scale Denominator} = \frac{50,000}{2} = 25,000 \Rightarrow 1 : 25,000
Map enlargement increases the scale of the map, which means decreasing the scale denominator by dividing it by the linear scale factor.

Cevap

Depression matches inwardly decreasing closed contours; Conical hill matches inwardly increasing closed contours; Concave slope matches closely spaced upper contours transitioning to widely spaced lower contours; Escarpment matches extremely tight parallel contours along a linear slope face.
Each landform is uniquely characterized by its contour signature: closed loops decreasing inward represent depressions, closed loops increasing inward mark conical hills, contours spreading out downhill indicate concave slopes, and tightly clustered parallel contours represent escarpments.

Adım Adım Çözüm

1
Examine contour patterns for closed loop elevations.
Decreasing inward values indicate a depression, while increasing inward values represent a hill.
Contour values represent height above sea level; dropping values inside a loop signify a basin or pit.
2
Analyze contour spacing relative to elevation changes.
Close spacing near the top and wide spacing near the bottom forms a concave slope.
Closer contour lines represent steeper gradients, whereas wider spacing indicates flatter terrain.
3
Identify linear tight contour clustering.
Merged or nearly touching contours along a slope face depict an escarpment or cliff.
A steep vertical cliff compresses horizontal distance between successive vertical intervals.

A field surveyor analyzing a topographical map with a scale of 1:50,0001 : 50,000 measures a straight line distance of 4 cm4\text{ cm} along a road connecting Hilltop Village at an elevation of 350 m350\text{ m} and Valley Junction at an elevation of 150 m150\text{ m}. What is the gradient of the road between these two settlements?

Cevabı ve açıklamayı göster

Cevap: 1 in 101 \text{ in } 10

Cevap

The gradient of the road is 1 in 101 \text{ in } 10.
The gradient is determined by dividing Vertical Interval (VI) by Horizontal Equivalent (HE). With a VI of 200 m200\text{ m} (350 m150 m350\text{ m} - 150\text{ m}) and a ground distance HE of 2,000 m2,000\text{ m} (4 cm×50,000=200,000 cm=2,000 m4\text{ cm} \times 50,000 = 200,000\text{ cm} = 2,000\text{ m}), the ratio 2002,000\frac{200}{2,000} simplifies to 110\frac{1}{10} or 1 in 101 \text{ in } 10.

Adım Adım Çözüm

1
Calculate the Vertical Interval (VI)
VI=350 m150 m=200 m\text{VI} = 350\text{ m} - 150\text{ m} = 200\text{ m}
Vertical Interval is the difference in elevation between the two points.
2
Calculate the Horizontal Equivalent (HE) in meters
HE=4 cm×50,000=200,000 cm=2,000 m\text{HE} = 4\text{ cm} \times 50,000 = 200,000\text{ cm} = 2,000\text{ m}
Horizontal Equivalent is the actual ground distance converted to the same unit as VI.
3
Compute the slope gradient ratio
Gradient=VIHE=200 m2,000 m=110\text{Gradient} = \frac{\text{VI}}{\text{HE}} = \frac{200\text{ m}}{2,000\text{ m}} = \frac{1}{10} or 1 in 101 \text{ in } 10
Gradient is defined as the ratio of Vertical Interval to Horizontal Equivalent.

During a flood monitoring operation along the Benue River basin, hydrologists require satellite imagery that can penetrate dense cloud cover and function effectively during both day and night. Which remote sensing system is most suitable for this task?

Cevabı ve açıklamayı göster

Cevap: Active microwave radar remote sensing

Cevap

Active microwave radar remote sensing is the most suitable system because radar operates at long electromagnetic wavelengths that penetrate clouds and rain, and active sensors supply their own illumination allowing night-time imaging.
Active microwave radar remote sensing uses synthetic aperture radar (SAR) or similar active instruments that generate their own radiation in the microwave portion of the spectrum. Long microwave signals penetrate cloud cover, fog, and rain, while self-illumination allows data acquisition regardless of daylight.

Adım Adım Çözüm

1
Analyze the operational constraints specified in the scenario.
Identified key requirements: cloud penetration and round-the-clock (day/night) imaging capacity.
Selecting an appropriate remote sensing sensor requires matching environmental conditions with sensor spectral bands and energy sources.
2
Evaluate sensor energy source types (active vs. passive).
Active sensors emit their own energy pulses and do not depend on solar radiation, enabling night operation.
Passive sensors relying on reflected solar radiation cannot acquire data at night.
3
Evaluate atmospheric penetration across spectral bands.
Microwave wavelengths (1 mm to 1 m) easily pass through atmospheric cloud droplets and precipitation particles.
Shorter visible and infrared wavelengths suffer severe atmospheric scattering and absorption by clouds.

On a topographical map with a scale of 1:60,0001 : 60,000, a railway track connects Hill Station XX at an elevation of 460 m460\text{ m} to Junction YY at an elevation of 340 m340\text{ m}. If the distance between the two points measured along the map is 5 cm5\text{ cm}, what is the average gradient of the slope between Station XX and Junction YY?

Cevabı ve açıklamayı göster

Cevap: 1 in 251 \text{ in } 25

Cevap

The average gradient between Station X and Junction Y is 1 in 251 \text{ in } 25.
The vertical interval between the two stations is 460 m340 m=120 m460\text{ m} - 340\text{ m} = 120\text{ m}. Using the map scale of 1:60,0001 : 60,000, a map distance of 5 cm5\text{ cm} represents a ground horizontal distance of 5×60,000 cm=300,000 cm=3,000 m5 \times 60,000\text{ cm} = 300,000\text{ cm} = 3,000\text{ m}. Dividing the vertical interval by the horizontal equivalent gives 1203000=125\frac{120}{3000} = \frac{1}{25}, which is expressed as 1 in 251 \text{ in } 25.

Adım Adım Çözüm

1
Calculate the Vertical Interval (VI)
VI=460 m340 m=120 m\text{VI} = 460\text{ m} - 340\text{ m} = 120\text{ m}
The Vertical Interval is the absolute difference in elevation between the two points.

Calculate the Horizontal Equivalent (HE) in meters
HE=5 cm×60,000=300,000 cm=3,000 m\text{HE} = 5\text{ cm} \times 60,000 = 300,000\text{ cm} = 3,000\text{ m}
Convert the measured map distance to ground distance using the representative fraction scale, then convert centimeters to meters.

What is the gradient of the slope between the radio mast and the valley bridge?

Cevabı ve açıklamayı göster

Cevap: 1 in 101 \text{ in } 10

Cevap

The gradient of the slope is 1 in 101 \text{ in } 10.
The slope gradient is defined as the ratio of Vertical Interval (VI) to Horizontal Equivalent (HE). The vertical rise between the radio mast (480 m480\text{ m}) and the bridge (180 m180\text{ m}) is 300 m300\text{ m}. The actual ground distance represented by 10 cm10\text{ cm} on a 1:30,0001 : 30,000 scale map is 10×30,000 cm=300,000 cm=3,000 m10 \times 30,000\text{ cm} = 300,000\text{ cm} = 3,000\text{ m}. Dividing the vertical rise by the horizontal distance gives 3003000=110\frac{300}{3000} = \frac{1}{10}, expressed as a ratio of 1 in 101 \text{ in } 10.

Adım Adım Çözüm

1
Calculate the Vertical Interval (VI)
VI=480 m180 m=300 m\text{VI} = 480\text{ m} - 180\text{ m} = 300\text{ m}
Vertical Interval is the difference in height between the highest point and the lowest point.

What is the central angle, in degrees, of the sector representing oil palm products?

Cevabı ve açıklamayı göster

Cevap: 81

Cevap

The central angle of the sector representing oil palm products is 8181^\circ.
The correct answer is obtained by finding the component share of the total value (108 / 480 = 0.225) and multiplying by 360 degrees, yielding an angle of 81 degrees.

Adım Adım Çözüm

1
Calculate the fractional proportion of the specific component relative to the total data value
108480=0.225\frac{108}{480} = 0.225
A sector in a pie chart represents a fractional part of the total statistical value.
2
Convert the calculated proportion into degrees of a circle
0.225×360=810.225 \times 360^\circ = 81^\circ
A full pie chart circle contains 360360^\circ, so multiplying the component proportion by 360360^\circ gives its angular representation.

A cartographer is tasked with displaying population density across different administrative districts in a state by applying varying intensities of shading, where darker shades represent higher densities. Which statistical mapping technique is being described, and what is a primary cartographic limitation of this method?

Cevabı ve açıklamayı göster

Cevap: Choropleth map, which falsely assumes a uniform distribution of the phenomenon throughout each administrative unit.

Cevap

The correct mapping technique is a choropleth map, whose primary limitation is creating an illusion of uniform population distribution across the entire administrative unit.
A choropleth map uses tonal shading or graduated colors applied to specific boundary units (such as states or districts) to display average values or densities. A major limitation of this technique is the false assumption that population density is evenly distributed across the entire area inside each boundary.

Adım Adım Çözüm

1
Identify the mapping technique based on the spatial data display method.
The technique using varying shades or patterns applied within pre-defined administrative boundaries to show density or average values is a choropleth map.
Choropleth mapping relies on quantitative areal data aggregated by spatial units such as states or districts.
2
Analyze the cartographic limitations of choropleth maps.
Choropleth shading covers entire administrative zones evenly, giving the false impression that values are uniform throughout each zone.

During a long-distance linear measurement along a proposed road alignment, two survey assistants are conducting a chain survey. At the end of every full chain length laid on the ground, which surveying accessory is driven into the ground by the leader to mark the position and assist in tallying the total distance measured?

Cevabı ve açıklamayı göster

Cevap: Marking arrows

Cevap

Marking arrows are used by the leader at the end of each full chain length to mark the spot and keep count of the distance measured.
Marking arrows (chaining pins) are small steel wire pins used during chain surveying. The leader carries a bundle of arrows and inserts one into the ground at the end of every full chain length. As the survey progresses, the follower picks them up. The number of arrows collected by the follower at any point indicates the exact number of full chain lengths measured.

Adım Adım Çözüm

1
Identify the fieldwork process described
The process described is measuring a continuous long distance along a line using a chain, involving a follower and a leader.
Chain surveying over long distances requires tracking how many full chain lengths have been measured.
2
Analyze the function of each surveying accessory
Marking arrows (chaining pins) are specifically supplied in sets (usually 10) for insertion into the ground at the forward end of each chain length by the leader. The follower collects them as they move forward, providing an exact tally.
Distinguishing between station marking accessories (pegs), alignment accessories (ranging poles), offset accessories (offset rods), and tallying accessories (arrows) is essential for accurate survey procedure.
