Automated Extraction, Refinement, and Update of Road Databases from Imagery and Other Data
Roads are important objects for many applications of topographic data such as car navigation systems. They are often acquired manually and as this entails significant effort, automation is desirable. Deficits in automation, particularly linked to human interaction have led to the formation of this EuroSDR working group on the automated extraction, refinement, and update of road databases from imagery and other data. In the introductory part of this report we give a short account of the working group's motivation and the actual implementation in terms of actions. After showing why and how we limit the scope of the report we present an analysis of questionnaires to producers of road data as well as researchers and manufacturers. Based on it, the main focus has been the setup of a test comparing different approaches for automatic road extraction. After describing the data and the evaluation criteria used, we briefly present the approaches of a number of groups which have submitted results and give the outcome of the evaluation of these results. Finally, after thoroughly analyzing the evaluation results, we present conclusions and recommendations Show more
