Abstract:There is currently high interest in developing automated methods to assist the updating of map databases. This study presents methods for automatic detection of buildings and changes in buildings from airborne laser scanner and digital aerial image data and shows the potential usefulness of the methods with thorough experiments in a 5 km 2 suburban study area. 96% of buildings larger than 60 m 2 were correctly detected in the building detection. The completeness and correctness of the change detection for buildings larger than 60 m 2 were about 85% (including five classes). Most of the errors occurred in small or otherwise problematic buildings.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
