UNDERGROUND UTILITY MAPPING WITHIN UNIVERSITY OF BENIN, UGBOWO CAMPUS USING DGNSS

ABSTRACT

This study was carried out to produce a Utility map of the University of Benin. The objectives were to Identify the locations of underground utilities using Global Navigation Satellite System and to generate the information from the data obtained in the form of maps. This contains methods and procedures followed in data acquisition, processing, and manipulation of data obtained from the field and also from secondary sources in order to achieve the aim of the project. The field work was carried out in July of 2023. TERSUS DAVID GNSS was used to get the X, Y and Z data, the rover was connected to Geosystem CORS, which was used to get the X,Y,Z coordinates for all the utilities within the study area while the antenna of the rover was set at 200cm was used to get the height. The field data was downloaded from the Data logger and copied to a notepad and then opened in Microsoft Excel environment. The excel file was opened in ArcMap using display X, Y data tool and subsequently converted to shapefile format. The shapefile was added as layer. The layer was overlaid on the Google Earth image of the study area, there was a little shift, which was corrected using spatial adjustment tool in ArcGIS. The result of the underground mapping project at the University of Benin using GNSS technology has yielded a comprehensive and accurate database of underground utilities. This mapping effort has provided valuable insights into the location, depth, type, and condition of various utility networks on campus. By harnessing the power of GNSS technology, the university has significantly improved its infrastructure management, safety protocols, and maintenance practices. The mapping data serves as a foundational resource for future development projects, ensuring efficient resource allocation, minimizing disruptions, and enhancing the overall sustainability of the campus infrastructure.
