Moutamanro/Nile-Sudan-MultiSite-ML-Dataset

Machine-learning-ready geospatial dataset generated in Google Earth Engine (GEE) for Nile River hydrological and remote sensing analysis in Sudan. Includes Sentinel-1, Sentinel-2, terrain, rainfall, and spectral index features for flood mapping, water detection, and environmental ML applications. # Nile Sudan MultiSite ML Dataset ## Overview This repository contains the **Nile Sudan MultiSite ML Dataset**, a machine-learning-ready geospatial dataset generated using Google Earth Engine (GEE) for hydrological and remote sensing analysis in Sudan along the Nile River system. The dataset was developed for supervised machine learning applications related to: - flood mapping, - water-body detection, - hydrological monitoring, - and environmental classification. --- ## Study Area The dataset focuses on selected Nile River regions in Sudan, including areas surrounding the Merowe region and associated hydrological zones. Primary study region: - Merowe Dam region, Sudan --- ## Data Sources The dataset was generated using multiple remote sensing and terrain products available in Google Earth Engine: ### Satellite Data - Sentinel-1 SAR imagery - Sentinel-2 multispectral imagery ### Terrain and Hydrological Data - Digital Elevation Model (DEM) - Terrain derivatives: - elevation - slope - aspect - flow accumulation ### Climate Data - Rainfall products extracted from GEE climate datasets --- ## Dataset Features The dataset includes the following predictor variables: | Feature | Description | |---|---| | NDVI | Normalized Difference Vegetation Index | | NDWI | Normalized Difference Water Index | | MNDWI | Modified NDWI | | VV | Sentinel-1 SAR backscatter | | blue | Sentinel-2 blue band | | green | Sentinel-2 green band | | red | Sentinel-2 red band | | nir | Near Infrared band | | swir1 | Shortwave Infrared 1 | | swir2 | Shortwave Infrared 2 | | elevation | Terrain elevation | | slope | Terrain slope | | aspect | Terrain aspect | | flow_acc | Flow accumulation | | rainfall_mean | Mean rainfall | | rainfall_sum | Total rainfall | | label | Classification label | | random | Randomized split variable | --- ## Coordinate System The dataset was generated within the Google Earth Engine en …
