Скачать или смотреть Soil Salinity Mapping using Google Earth Engine | Sentinel-1 & Sentinel-2 Hybrid Index Tutorial

Unlock the power of satellite data for agriculture and land monitoring! 🌍 In this step-by-step Google Earth Engine (GEE) tutorial, you'll learn how to perform hybrid soil salinity mapping using Sentinel-2 (optical) and Sentinel-1 (radar) imagery.

🔬 We compute the Soil Salinity Index (SI), normalize datasets, and blend both sources into a single Hybrid Salinity Index — followed by classification into 4 salinity zones with a dynamic legend.

This technique is valuable for:
✅ Sustainable agriculture
✅ Land degradation assessment
✅ Irrigation planning
✅ Precision farming research

📌 Covered in this tutorial:

AOI setup & date range (April–May 2025)
Soil Salinity Index using SWIR & NIR
Moisture analysis via Sentinel-1 VV backscatter
Data normalization
Hybrid index formula
Classified salinity zones
Visualization & export
Custom interactive legend
