This study simulates multispectral remote sensing data from high-resolution field spectra. It enables accurate quantitative analysis of landscape features like vegetation and soil in remote sensing applications.
Area of Science:
- Earth and Space Sciences
- Remote Sensing Technology
- Geospatial Analysis
Context:
- Landscape spectral characteristics are fundamental to remote sensing applications.
- Scale differences and instrument resolution introduce errors in spectral data, hindering quantitative analysis.
- Accurate spectral information retrieval is crucial for remote sensing applications.
Purpose:
- To propose a method for simulating multispectral image spectra from high-resolution field endmember spectra.
- To address the challenges of spectral curve and reflectance discrepancies in remote sensing.
- To enable quantitative retrieval of special information from remote sensing data.
Summary:
- The study describes optical imaging simulation principles and proposes a method to simulate low-resolution multispectral data from high-resolution field spectra.
- Field-measured endmember spectra of vegetation and soil from the Tarim Basin were simulated for the AVNIR-2 sensor.
- A strong correlation was found between simulated and actual AVNIR-2 pixel spectra, validated by statistical analysis.
Impact:
- The developed linear model facilitates quantitative transformation from endmember to pixel scale.
- This research provides a realistic approach for enhancing quantitative remote sensing applications.
- Improved accuracy in remote sensing data analysis for environmental and resource management.
