owusugeorge946-afk/urban-heat-risk-spatial-networks: v1.0.1.0 – Urban Heat Risk Spatial Networks Reproducibility Package

Initial reproducibility release supporting the manuscript: "Spatial Networks of Urban Surface Heat Risk: Connectivity, Communities and Neighbourhood Reinforcement across Four West African Coastal Cities" This release provides the analytical workflow used for the four-city assessment of Accra, Lagos, Abidjan and Freetown. Included materials: Google Earth Engine workflow for 2024 remote-sensing preprocessing Sentinel-2 land-use/land-cover classification using a 200-tree Random Forest Landsat 8/9 land-surface temperature, NDVI and NDBI processing Heat Risk Index (HRI) construction 500 m analytical-grid preparation Environmental-similarity weighted spatial-network construction Network topology and centrality analysis Leiden community detection Similarity-conditioned HRI propagation Sensitivity and robustness analysis Reproducibility documentation and manuscript benchmark information The original Sentinel-2 and Landsat observations are publicly accessible through the Google Earth Engine Data Catalog. Important reproducibility note: The original manually digitised LULC training geometries are retained as Imports in the authors' Google Earth Engine project and are therefore not embedded directly in this GitHub release. The supplied GEE script documents the exact variable names expected for these training data. Version: 1.0.0 Release year: 2026
