TASC Geography Level 3 Practice Questions - TASC Geography Level 3 (GGY315120) Exam - TASC Geography Level 3 Practice Questions

Question 1

On a topographic map with a scale of 1:25,000, two rural Tasmanian fire stations are separated by a distance of 8.0 centimeters. What is the actual straight-line distance between these two stations on the ground?

2.0 kilometers 0.2 kilometers 20.0 kilometers 8.0 kilometers

Correct Answer:

2.0 kilometers

Question 2

A field survey team measures Spot Height A at 120 meters elevation and Spot Height B at 440 meters elevation. If the horizontal map distance between Spot Height A and Spot Height B is 1,600 meters, what is the average slope gradient along this transect?

1 in 5 (20%) 1 in 4 (25%) 1 in 10 (10%) 1 in 2 (50%)

Correct Answer:

1 in 5 (20%)

Question 3

Which of the following spatial data representations best distinguishes a raster data structure from a vector data structure in a Geographic Information System (GIS)?

Raster represents spatial features using a continuous grid of pixel cells with values, whereas vector represents features using discrete points, lines, and polygons defined by coordinates. Raster uses latitude and longitude coordinate vectors, whereas vector uses pixel brightness values from satellite sensors. Raster is strictly used for socio-economic census data, whereas vector is exclusively used for digital elevation models. Raster data cannot store quantitative numeric attributes, whereas vector data stores only qualitative image colors.

Correct Answer:

Raster represents spatial features using a continuous grid of pixel cells with values, whereas vector represents features using discrete points, lines, and polygons defined by coordinates.

Question 4

A remote sensing analyst processes multispectral satellite imagery to measure forest canopy health. In a specific cell, Near-Infrared (NIR) reflectance is measured at 0.60 and Red spectral reflectance is measured at 0.20. What is the Normalized Difference Vegetation Index (NDVI) for this cell?

0.50 0.40 0.80 0.33

Correct Answer:

0.50

Question 5

A spatial scientist needs to detect annual river channel migration over a 30-year period. Which satellite remote sensing resolution parameter is MOST critical for selecting an appropriate historical satellite dataset?

Temporal resolution, ensuring consistent historical imagery repeat cycles over the 30-year observation period. Radiometric resolution, ensuring 16-bit color quantification over 8-bit quantification. Spectral resolution, ensuring hyperspectral band narrowness in the ultraviolet spectrum. Thermal resolution, ensuring surface kinetic temperature measurement.

Correct Answer:

Temporal resolution, ensuring consistent historical imagery repeat cycles over the 30-year observation period.
