The Correct Option is C
Solution and Explanation
Step 1: Understanding resampling in remote sensing.
Resampling is a process of modifying the spatial resolution or correcting distortions in images.
Step 2: Types of resampling. - Value correction: Changes the pixel's digital number (DN) based on interpolation techniques. - Location correction: Adjusts pixel positions to align with a reference coordinate system.
Step 3: Selecting the correct option. Since resampling affects both pixel values and location, the correct answer is c. Both.
