A Test of Automatic Road Extraction Approaches

Abstract

Roads are important objects for many applications of topographic data. They are often acquired manually and as this entails significanteffort, automation is highly desirable. Deficits in the automatic extraction hindering a wide-scale practical use haveled to the ideaof setting-up a EuroSDR test comparing different approaches for automatic road extraction. The goal is to show the potential of thestate-of-the-art approaches as well as to identify promising directions for research and development. After describing the data and theevaluation criteria used, we present the approaches of a number of groups which have submitted results and give a detailed discussionof the outcome of the evaluation of the submitted results. Wefinally present a summary and conclusions.
