Question

Match List-I with List-II. List-I Terminology used in Remote sensing: A. Active sensing, B. Passive sensing, C. Spectral, D. Spatial. List-II Detail: I. When the sensing device detects EMR originating from another source primarily from sun, II. It is the change in reflectance or emission of objects as a function of wavelength, III. It is the arrangement of terrain features providing attributes such as shape, size and feature, IV. When the sensing device detects EMR at an object and detects the amount of that energy which is reflected back.

• A. A-IV, B-II, C-III, D-I
• B. A-I, B-II, C-III, D-IV
• C. A-III, B-II, C-I, D-IV
• D. A-IV, B-I, C-II, D-III

Hint:

Active sensing uses its own energy source, while passive sensing depends on natural radiation.
