Road network spatial data co-registration of different sources using imagery-to-GIS mining

This paper presents an integration method for co-registration between up-to-date aerial imagery and geospatial database with emphasis on road network data, which is called image-to-GIS co-registration. The up-to-date aerial imagery and their extracted features are thought as reference data, and the early GIS data are co-registered onto aerial images after orthorectified in order to integrated two datasets. The work includes two main steps: (1) The aerial image is first orthorectified into orthoimage; and (2) Road network information is extracted using GIS-assistant imagery mining techniques.
