Integrated investigations involving remote sensing and geology have been conducted with the aim of modeling groundwater potential zones within Akure metropolis, Ondo State, Southwestern Nigeria. Groundwater potential zones were delineated with the help of remote sensing and geology. Land sat imageries were used for land use/land cover mapping and lineament analysis for groundwater prospecting. Radar Digital Elevation Model was used for drainage network extraction, slope and geomorphological analysis. All the thematic maps were generated and analyzed in terms of hydrogeological importance and reclassified for integration using ArcGIS 10.5 software. The slope, landuse/landcover, drainage density, lineament density, geomorphology and geological maps generated were integrated with overlay weighted in ArcGIS environment. Suitable ranking and weighting factors were decided based on their capability to store groundwater. This procedure is repeated for all the other layers and resultant layers were reclassified. The groundwater potential zones are classified into five categories of very low, low, moderate, high and very high. The groundwater potential within Akure metropolis is rated as generally low.
