The routing of power distribution and transmission lines is an important step to bring energy and modernize the lives of the population. The process involves complex multiple criteria decision-making. The area of interest must be carefully modeled in weighted and restricted areas based on geospatial data. This paper brings a methodology based on geoprocessing and Voronoi polygons to obtain one of the most important restricted areas in energy distribution lines, the rivers. Rivers are areas that should be avoided when their width exceeds the maximum distance between poles. The methodology consists in generate Voronoi edges from which the medial axis and the width of each point of the river are obtained. Then, a buffer is placed in each vertex of the river higher than a threshold. The result to the case study brings a restricted area of rivers of the State of Parana to help decision-makers in routing distribution energy lines with more assertiveness.
