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.

Remote sensing has only one resolution i.e. spectral resolution. D. NOAA was the first operational remote sensing satellite system. E. In remote sensing the sensors are used to detect EMR.

Arrange in a sequence the following stages of remote sensing. A. Detection of the energy by the sensor converting into photographic image or electrical output, B. Interaction between energy and earth surface or self emission, C. Transmission of the emitted or reflected energy to the remote sensor, D. Origin of electromagnetic energy, E. Transmission of energy from the source to the earth surface and its interaction with atmosphere.

Given below are two statements: Assertion (A): Remote sensing is the study of any object without making actual contact with the object under consideration. Reason (R): The electromagnetic radiation reflected or emitted from the object is a common source of remote sensing apart from other sources such as gravity or magnetic fields.

The first operational remote sensing satellite is:

Given below are two statements: Assertion (A): Remote sensing and GIS applications have potential for rapid monitoring of spatial and temporal variations in land features. Reason (R): The GIS permits multi-layer maps of various features of investigation that help in developing alternative plans for drainage system design and layout.

When the sensor detects EMR at an object and detects the amount of that energy which is reflected back, it is:
