How do you ensure the accuracy and reliability of remote sensing results in your research?

Sample interview questions: How do you ensure the accuracy and reliability of remote sensing results in your research?

Sample answer:

Accuracy Verification:

  • Ground-Truth Validation: Compare remote sensing data with direct field measurements or known features on the ground.
  • Cross-Validation: Use different remote sensing platforms, sensors, or algorithms to cross-check results and reduce uncertainty.
  • Statistical Analysis: Employ statistical tests (e.g., regression, error analysis) to evaluate the correlation and accuracy between remote sensing data and ground-truth measurements.

Reliability Enhancement:

  • Sensor Calibration and Validation: Regularly calibrate remote sensing instruments to ensure consistent data acquisition. Validate sensor performance through rigorous testing and inter-comparison.
  • Data Pre-Processing: Apply appropriate pre-processing steps (e.g., atmospheric correction, noise reduction) to improve data quality and enhance the interpretability of results.
  • Quality Assuran… Read full answer
