🛠️ What is InSAR?

Interferometric Synthetic Aperture Radar (InSAR) is a radar technique used to generate maps of surface deformation or digital elevation models using differences in the phase of radar waves returning to the satellite. InSARLite makes this powerful technique accessible through:

• Automated workflows for complex processing chains
• Interactive tools for network design and parameter selection
• Professional visualization for scientific analysis and publication

🔧 System Requirements

Minimum

• OS: Ubuntu 20.04/22.04 LTS
• Python: 3.8+
• RAM: 8 GB
• Storage: 50 GB free space
• Network: Internet connection for data downloads
• NASA Earthdata Account: Required (Register here)

Recommended

• OS: Ubuntu 22.04 LTS
• Python: 3.9 or 3.10
• RAM: 16 GB+
• Storage: 100 GB+ SSD
• CPU: Multi-core (4+ cores for parallel processing)

📊 Processing Workflow

InSARLite implements a complete 7-step InSAR processing pipeline:

1. Project Setup - Define study area, time period, and download data
2. Data Preparation - Organize and validate Sentinel-1 acquisitions
3. Baseline Planning - Design interferometric network and select master scene
4. Orbit Processing - Download and apply precise orbit corrections
5. Interferometry - Generate interferograms and coherence maps
6. Phase Unwrapping - Convert wrapped phase to displacement measurements
7. Time Series Analysis - SBAS processing for deformation time series

🎯 Use Cases

InSARLite is designed for:

• 🔬 Research: Academic studies in geodesy, geophysics, and remote sensing
• 🎓 Education: Teaching InSAR principles and processing workflows
• 📊 Analysis: Scientific analysis of surface deformation (landslides, subsidence, earthquakes, volcanoes)
• 📖 Learning: Comprehensive tutorial with real-world Turkey landslide case study

🙏 Acknowledgments

InSARLite is built on the foundation of GMTSAR - an excellent open-source InSAR processing system developed by the GMTSAR team at Scripps Institution of Oceanography, UC San Diego.

Special appreciation to:

• GMTSAR Development Team - For creating and maintaining the robust SAR processing toolkit that powers InSARLite
• Dr. David Sandwell and Dr. Xiaopeng Tong - For their leadership in GMTSAR development
• The entire GMTSAR community - For continuous improvements, bug fixes, and scientific contributions

InSARLite serves as a user-friendly interface to GMTSAR's powerful capabilities, making advanced InSAR processing more accessible to researchers and practitioners worldwide. Without GMTSAR's solid foundation, InSARLite would not exist.
