Abstract
Water is a vital resource used in effective sanitation, hygiene, drinking and agricultural uses. This study was in Obudu Plateau covering an area of 3,053.08km2. Analysis of remote sensing, geographic information system (GIS), and global positioning system (GPS) data obtained from satellite imageries and digital elevation model (DEM) assessed groundwater potential. The model was validated using borehole data in the area. Thematic layers of geology, lineament density, slope, geomorphology, land use and land cover and drainage density were integrated using GIS software. Multicriteria evaluation of the layers was by analytic hierarchy process (AHP). Pairwise comparison matrix shows consistency the consistency ratio is 0.07 or 7%. This shows the comparison of groundwater controlling factors is within acceptable limit of consistency. Overlay analysis produced groundwater potential map classified into five zones of very high 2.66% (81.31km2), high 6.92% (211.38km2) very low 9.60% (292.69km2), moderate 46.95% (1,433.46 km2) and low 33.87% (1,034.23km2). Structural geological setting determines largely the suitability of an area to groundwater occurrence. Overlaying each thematic layer with lineament density map produced a more credible groundwater potential model compared to preceding related works. This method is suitable for both local and regional groundwater development.
期刊介绍：
Applied Geomatics (AGMJ) is the official journal of SIFET the Italian Society of Photogrammetry and Topography and covers all aspects and information on scientific and technical advances in the geomatics sciences. The Journal publishes innovative contributions in geomatics applications ranging from the integration of instruments, methodologies and technologies and their use in the environmental sciences, engineering and other natural sciences.
The areas of interest include many research fields such as: remote sensing, close range and videometric photogrammetry, image analysis, digital mapping, land and geographic information systems, geographic information science, integrated geodesy, spatial data analysis, heritage recording; network adjustment and numerical processes. Furthermore, Applied Geomatics is open to articles from all areas of deformation measurements and analysis, structural engineering, mechanical engineering and all trends in earth and planetary survey science and space technology. The Journal also contains notices of conferences and international workshops, industry news, and information on new products. It provides a useful forum for professional and academic scientists involved in geomatics science and technology.
