Geospatial analysis of the Urban Heat Island effect in Accra using Landsat data and GIS tools. # Urban-Heat-Analysis-Accra Geospatial analysis of the Urban Heat Island effect in Accra using Landsat data and GIS tools. # Urban Heat Island Analysis in Accra This project explores the Urban Heat Island (UHI) effect in Accra, Ghana, using Landsat satellite imagery and geospatial analysis. ## Objectives - Assess spatial patterns of urban heat in Accra. - Identify hotspots and their relation to land use/land cover. - Demonstrate how remote sensing and GIS can support urban planning. ## Data Sources - Landsat 8 (Thermal Infrared Sensor) from USGS Earth Explorer. - Population and land use data from Ghana Statistical Service (GSS). ## Tools & Methods - QGIS 3.30 for spatial preprocessing and map production. - Python (geopandas, rasterio, matplotlib) for data analysis. - ArcGIS Pro for visualization and hotspot mapping. ## Results - Accra’s central areas show significantly higher surface temperatures. - Peripheral green zones mitigate urban heat. - Produced thematic maps for UHI distribution. ## Repository Structure
