0:00 Downloading Sentinel-1 Data 2:56 Radar Image Processing in SNAP 10:31 Processing and Analysis in QGIS 25:11 Analysis Using Google Earth Engine In this video, we performed a professional radar analysis using Sentinel-1 satellite data to detect ground variations, fractures, cracks, and rock edges using SNAP and QGIS software, and then applied the same analysis directly in Google Earth Engine. During this tutorial, we learned: • Processing Sentinel-1 data within SNAP • Noise removal and radar data enhancement • Converting VV and VH data to dB • Creating a radar contrast index • Color interpretation within QGIS • Understanding radar reflections • Performing the same analysis within Google Earth Engine 🎨 Color interpretation within the analysis: 🔵 Blue = Calm and stable areas 🟢 Green = Moderate variations 🟡 Yellow = Significant changes and slopes 🔴 Red = Strong reflections, edges, and ground fissures 💻 The analysis is based on: Sentinel-1 SAR Radar VV/VH Polarization Radar Backscatter Analysis Terrain Contrast Interpretation ⚠️ Important note: This analysis does not definitively identify the target type, but rather reveals variations in radar response, surface characteristics, slopes, and geological variations.
