The automated detection and removal of spatial conflicts remains unsolved in map generalization. There are many methods aiming at this question, but it is still an open question. Several impacts, such as the characteristic of spatial conflict, spatial context and others, should be considered in the process. Based on the idea of causes classification and spatial competition a comprehensive method is presented to detect conflicts by delaunay triangulation. After conflict detection, a hierarchical classification of conflict is constructed. Corresponding operator or model for each kind of conflict is proposed. Results of this new method obtained on real data are discussed.
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.
