Application of GIS in Electricity Distribution: A Case Study of part of Ashamu Layout Kosobo, Oyo East Local Government Area, Oyo State Nigeria

ABSTRACT

Due to the natural limitations faced by the old system of keeping, planning and managing the distribution of electricity, a computerized system is developed for Power Holding Company of Nigeria (PHCN), on Ashamu Layout of Kosobo Area, Oyo State, Nigeria. Data was acquired using south total station (NTS) and the data was downloaded using NTS.comp and project boundary was plotted with AutoCAD civil 3D, 1m Ikonos resolution satellite imagery was downloaded and geo-referenced with Arcgis10.1. Spatial features such as roads and buildings were vectorized. Electricity distribution and management was designed and created using relational database management system (rdbms) approach. The raster image was added as layer to ArcGIS 10.1 environments for geo-referencing and vectorization. The roads, buildings, electric poles were vectorized and a south total station was used to acquire co-ordinates of the electric poles and transformers to their position on the imagery, creating spatial database for the study area. The developed system was tested by carrying out spatial analysis and spatial search using ArcGIS 10.1. The results obtained were displayed in graphics and tables. It was established from the result that Geographic Information System (GIS) has the capacity as an effective tool for management of electricity distribution system.
