MNDWI and NIR extraction for uranium‑gold conflict zones, Sudan: Process pre‑war (2023) and wartime (2025)

Google Earth Engine (GEE) JavaScript script for extracting Sentinel‑2 MSI Level‑2A imagery during the dry seasons (January–March) of 2023 and 2025 for four study areas in Sudan: Uro, Kurun, Marrah, and Mun Mountains.

The script computes the Modified Normalized Difference Water Index (MNDWI) and extracts the Near‑Infrared (NIR) band (B8). For each combination of year and mountain, a median composite is generated, and the resulting raster layers are exported as GeoTIFFs at 10 m resolution for visual assessment in QGIS.

This script supports the analysis of land‑cover and hydro‑disturbance patterns associated with artisanal mining activities in conflict‑affected zones of Sudan.
