30 Questions
What does patterns on aerial photographs refer to?
The orderly spatial arrangement of features on the terrain
Which feature may narrow linear or parallel alignments of vegetation represent?
Fractures
What do wide curved alignments of vegetation signify according to the text?
Distribution of outcrops of gently dipping beds
Which aspect do drainage patterns primarily reflect?
Underlying geologic structure
Why are patterns resulting from particular distributions of gently curved or straight lines significant?
They represent faults and fault zones
What may wide curved alignments of vegetation indicate?
Moderately dipping beds
What is the main difference between an orthophoto and an orthoimage?
Orthophotos are digitized like a paper map while orthoimages have different geometric distortions.
How are satellite images and aerial photographs different in terms of spectral characteristics?
Satellite images have different spectral characteristics due to electronic recording, while aerial photographs lack these differences.
What correction is needed in satellite images to obtain an orthoimage?
Correcting different geometric distortions and other corrections known to exist in satellite images.
Why can electromagnetic radiation be transmitted through vacuum?
As it does not need a medium for transmission.
Which statement accurately describes the differences between satellite images and aerial photographs?
Satellite images must undergo corrections for geometric distortions that differ from aerial photographs.
What is a distinctive characteristic of electromagnetic radiation, as discussed in the text?
Can be transmitted through vacuum without a medium for transmission.
What is the relationship between Δp, b, h, H, and f according to the text?
Δp = b * h / (H - f)
What kind of information is determined by measuring linear dimensions like distances and angles, according to the text?
Metric information
In the context of aerial photography interpretation, what does semantic information refer to?
The nature or identity of objects imaged
What is the basic relationship of parallax difference to elements of the stereoscopic model called?
Parallax equation
From equation 2, if Δp = 10 and b = 5, what is the value of h when H = 20?
$h = 3.33$
What variable is used to determine the exact position of an object on the earth’s surface?
Photobase length
What is the major advantage of the Spot system's linear array?
Excellent geometry along the scan axis
How does the Spot system handle the problem of calibrating 6000 detectors?
By ensuring each detector is very small
What is the resolution of the Spot system in its MSS mode?
20m pixel size
Why is it mentioned that the Spot system does not need to point vertically to the ground?
To highlight its use of photogrammetric procedures
What is the main disadvantage associated with using many detectors in the Spot system's detector array?
Calibration complexity for a large number of detectors
In what scenario would the Spot system operate at a resolution of 10m pixel size?
Panchromatic mode
What is the pixel size in the Landsat Thematic Mapper (TM)?

What does each detector of the MSS do?
Integrates the lightness on the scan to influence the brightness value of the pixel
How does Landsat Thematic Mapper (TM) differ from the previous Landsat MSS?
Has increased radiometric sensitivity
What leads to the problem of resolution in remote sensing?
Contrast of the background influencing other features
How many points of differences were mentioned between Landsat Thematic Mapper (TM) and previous Landsat MSS?
Three
