摘要:The extraction of road crossings is often neglected by systems for automatic road extraction. Frequently, crossings arise as by-products of the grouping step. This leads to geometrical inaccuracies and visually and cartographically unsatisfactory results. In this paper, an approach for the improvement of extracted road crossings is presented as well as a method for the external evaluation of the extraction results
