Tutorial Overview

The Turkey Landslide Case Study provides a complete end-to-end demonstration of InSAR time series analysis using InSARLite. This tutorial uses real research data from the December 8, 2024 Güngören landslide event in northeastern Turkey.

What You’ll Learn

• Installation: GMTSAR automatic setup and verification

• Project Configuration: Data folder, AOI definition, temporal range

• Data Management: Querying, downloading, and extracting Sentinel-1 data

• Baseline Network: Interactive design using Base2Net tool

• Interferogram Generation: Alignment and IFG creation

• Phase Unwrapping: Masking, reference point selection, and unwrapping

• SBAS Analysis: Time series inversion and velocity mapping

• Visualization: Interactive exploration of deformation results

Dataset Details

• Location: Güngören, northeastern Turkey (41.34°N, 41.27°E)

• Event: Catastrophic landslide failure on December 8, 2024

• Satellite: Sentinel-1 ascending orbit

• Acquisitions: 60 scenes covering ~18 months

• Master Scene: August 29, 2023

• Subswath: IW2 (F2 only)

• Results: Mean VLOS velocities up to 25 mm/yr, precursory acceleration detected

Time and Storage Requirements

• Processing Time: ~50+ hours (highly dependent on CPU cores and internet speed)

• Storage Space: ~710 GB total (328.8 GB downloads + ~320 GB processing + ~60 GB outputs)

• Download Time: 1-3 hours (depends on internet connection)

• RAM: 16 GB minimum, 32 GB strongly recommended
