“Calibration is the poor step-child of remote sensing”
Many people still hesitate to use thermal imagery, because they feel they lack information on how to use it. In this episode of the Thermal Lens, Ellis Freedman, a consultant with over 20 years of experience including working in Landsat mission, and advising commercial companies, takes a deep dive into thermal missions. The subjects cover e.g.:
- What makes a thermal mission different from a mission imaging in visible spectral range?
- How do these differences influence the imagery?
- What is calibration, and why is it so important for the thermal sensors?
- What radiometry terms do users need to understand to work with thermal imagery?
This is the second part of a two-part-episode with Ellis. In the first part, we speak about what differentiates large agency missions from the emerging small commercial missions.
