|
|
|
|
This folder contains all the code and reports for Sentinel-1 SAR data analysis and visualization.
|
|
|
|
## Files Overview
|
|
|
|
### Core Analysis Functions
|
|
- `sar_analysis_functions.R` - SAR data loading, metrics calculation, field statistics
|
|
- `sar_visualization.R` - Interactive mapping functions using tmap
|
|
- `test_sar_analysis.R` - Test script for validating SAR analysis functions
|
|
|
|
### Reports & Notebooks
|
|
- `Interactive_SAR_Report.Rmd` - Main interactive HTML report (working version)
|
|
- `SAR_exploration_report.Rmd` - Alternative comprehensive report
|
|
- `SAR_quick_test.Rmd` - Quick test report for debugging
|
|
|
|
### Utility Scripts
|
|
- `generate_sar_report.R` - Automated report generation script
|
|
- `simple_sar_test.R` - Basic SAR data loading test
|
|
|
|
## Data Sources
|
|
|
|
The SAR data is located in: `../../../python_scripts/data/aura/weekly_SAR_mosaic/`
|
|
- Contains 8 weeks of Sentinel-1 data (weeks 26-33, 2025)
|
|
- VV, VH bands in linear scale, dB scale, and filtered versions
|
|
- Field boundaries from: `../../../pivot.geojson`
|
|
|
|
## Generated Outputs
|
|
|
|
Reports are generated in: `../../../output/`
|
|
- `Interactive_SAR_Report.html` - Main interactive report
|
|
- Other test outputs
|
|
|
|
## Usage
|
|
|
|
To generate the main interactive report:
|
|
```r
|
|
source("generate_sar_report.R")
|
|
```
|
|
|
|
Or run directly:
|
|
```r
|
|
rmarkdown::render("Interactive_SAR_Report.Rmd", output_file = "../../../output/Interactive_SAR_Report.html")
|
|
```
|
|
|
|
