 Radiometric calibration

Radiometric calibration is the process of converting raw sensor data from remote sensing instruments (such as satellite or aerial sensors) into meaningful physical values, typically radiance or reflectance. This process ensures that the measurements taken by these sensors are accurate and can be compared over time and across different sensors. The main steps involved in radiometric calibration include: 1. **Sensor Response Characterization**: Understanding how the sensor responds to various wavelengths of light.
