The verification of existing data is an important task in order to ensure a high level of data quality, such as is needed in geographic information systems (GIS). Today, this work is carried out manually by an operator, who compares vector data from databases with remotely sensed imagery. In this paper, a system for automated road data verification using digital image processing for the extraction of roads from aerial imagery and topological analysis in order to optimise the whole process in… CONTINUE READING
