## 4 Remote Sensing Platforms Used in Peatland Research
### Airborne-Based Remote Sensing
#### 4.2.4 Challenges and Limitations  
While airborne-based remote sensing offers significant potential for peatland research, several challenges and limitations must be acknowledged. First, the cost and logistical requirements associated with airborne campaigns can be substantial, limiting the extent and frequency of data acquisition. Weather conditions and cloud cover can impede data collection and affect image quality regarding passive remote sensing data acquisitions. Furthermore, interpreting remote sensing data often requires ground validation, which can be challenging in remote and inaccessible peatland areas. Nevertheless, future research is required, similar to the study by [PERSON] et al. (2019), which focuses on advancements in the calibration and validation of airborne hyperspectral imagery in Arctic peatland regions [103]. The research demonstrates the importance of rigorous calibration and validation practices in improving the quality and reliability of hyperspectral imagery analysis. [PERSON] et al. (2019) highlight the implications of their methodology for satellite image analysis, emphasising the need for accurate calibration and validation in peatland ecosystems. This study contributes to the refinement and reliability of airborne remote sensing data analysis in peatland studies [103]. \begin{table}
