The aerial RGB orthoimages were provided by the city hall of Campo Grande, state of Mato Grosso do Sul, Brazil. The orthoimages have a ground sample distance (GSD) equal to 10 cm. In total, 1057 orthoimages with dimensions 5619 × 5946 pixels were used in the experiments. These images were split in 99,473 patches, where 111,583 utility poles were identified as ground-truth.
