Using a supervised machine learning approach point clouds are firstly classified into one of three groups: building, ground, or unassigned. Ground points are further processed by a novel algorithm to extract a road network. The algorithm exploits the high variance of slope and height of the point data in the direction orthogonal to the road boundaries. Applying the proposed approach on a 40 million point dataset successfully extracted a complex road network with an F-measure of 76.9%.||Funding Details:||European Research Council||Type of material:||Conference Publication||Publisher:||IEEE||Copyright (published version):||2015 IEEE||Keywords:||Aerial laser scanning;Aerial imagery;Data fusion;Road detection;Machine learning;Hybrid indexing||DOI:||10.1109/IGARSS.2015.7326746||Language:||en||Status of Item:||Not peer reviewed||Conference Details:||2015 IEEE International Geoscience and Remote Sensing Symposium (IGARSS), Milan, Italy, 26 - 31 July 2015|
