Summary
This study details satellite data archives and temporal Fourier analysis (TFA) methods for global environmental datasets. The findings support infectious disease mapping using 8x8 km TFA surfaces derived from satellite remote sensing data.
Area of Science:
- Environmental Science
- Geospatial Analysis
- Remote Sensing
Background:
- Satellite data archives are crucial for long-term environmental monitoring.
- Temporal Fourier Analysis (TFA) is a key technique for processing time-series remote sensing data.
- Understanding data genesis is vital for reliable geospatial applications.
Purpose of the Study:
- To document satellite data archives and TFA methods for global remotely sensed datasets.
- To provide a detailed reference guide for the creation of these datasets.
- To evaluate inter-compatibility of different spatial resolution TFA products.
Main Methods:
- Utilized satellite data archives and processing methods.
- Applied temporal Fourier analysis (TFA) techniques.
- Covered global spatial resolutions of 1x1 km and 8x8 km.
- Evaluated inter-compatibility between 1x1 km and 8x8 km TFA products.
Main Results:
- Generated global remotely sensed datasets with 1x1 km and 8x8 km spatial resolution.
- Established the inter-compatibility between different resolution TFA products.
- Identified 8x8 km TFA surfaces as suitable for disease mapping procedures.
Conclusions:
- The documented methods provide a robust foundation for using global environmental datasets.
- The 8x8 km TFA products are recommended for infectious disease mapping applications.
- Future sensor continuity and data sources are considered for ongoing research.
