Facility Mapping of Street Lighting in Rivers State University Main Campus, Port Harcourt: Nigeria

The use of location-based technology provides a solution to complex, real-world problems for mapping the spatial location of features, planning, and management. The lack of adequate geospatial information on existing lighting facilities impedes works and physical planning departments of Rivers State University to accurately locate and respond to faulty lighting facilities. This prompted the study which is aimed to map the lighting facilities at Rivers State University main campus with the objectives of providing spatial and attribute information of lightening facilities, creation of a functional database of these facilities and identify their operational status. Secondary data such as projected coordinates of identified controls in Northings (m), Easting (m), and Ellipsoidal Heights (m) and shape file of Rivers State University were obtained from the data management unit of the Department of Surveying and Geomatics, Rivers State University. Global Positioning System data collection technique was utilized during field surveys to obtain primary data such as spatial and attributes data of the facilities with the aid of a Unistrong G970iipro RTKDifferential GPS and accessories with 2mm least count. The research noted numbers of functional and non-functional lightening facilities such as solar lights, transformers, electric street lights, among others. The result also showed that the roadways in the study area are well illuminated and have a high level of perceived safety and security at night. However, immediate repair and maintenance of the non-functional electric and solar lights cum providing lightning facilities in noted areas is necessary to ensure adequate lightening of the University main campus premises.
