Abstract This study spatially analyzed of Buildings on The Medium Voltage Overhead Powerline Right-Of-Way in Port Harcourt, Rivers State, Nigeria. To map medium voltage powerlines across the study area, ArcGIS 10.7.1. was used. The coordinates of each pole were acquired using the Global Positioning System (GPS). This was imported into the ArcGIS environment and enabled the mapping of medium voltage overhead powerlines across the study area. The overhead powerline right-of-way was obtained by buffering the powerlines with a distance of 11m to represent the stipulated setback. The lines were buffered to enabled the capturing of the buildings within the 11m setback from the powerlines. The result showed that about twenty-nine thousand and thirty (29,030) structures in the study area were under the menace of medium voltage powerline hazards. It is therefore recommended that, demolition of encroached buildings, landscaping and planting of trees and shrubs on powerline rights-of-ways should be encouraged as another way of greening the cities and improving urban ecology. This study therefore showcased the importance of Geographic Information System (GIS) in environmental monitoring and planning.
