Which of the following best describes the primary challenge that orthorectification aims to overcome in remote sensing imagery?
Question 2
In the context of orthorectification, if a raw image pixel at $(r, c)$ is transformed to a ground coordinate $(X, Y, Z)$, which of the following best describes the role of the sensor model in this transformation?
Question 3
When performing orthorectification, what is the most significant impact of using a Digital Elevation Model (DEM) with a significantly coarser resolution than the imagery being corrected?
Question 4
In orthorectification, if the ground control points (GCPs) used are inaccurately surveyed, what is the most likely consequence for the final orthorectified image?
Question 5
Which of the following mathematical concepts is most directly applied when a Digital Elevation Model (DEM) is used in orthorectification to correct for terrain displacement?
