EXPLANATION
Remote Sensing Sensors , Aerial Photography,
- Radiometric Sensor Calibration Equation:
- Sensor Parameters:
- The linear regression slope relating digital numbers (DN) to spectral radiance ($L$) measured by the sensor is defined as the Gain ($A$).
- The intercept represents the offset or bias. (Correct answer: Option 1)
