| Abstract: | In order to meet the heavy demands in checking the data quality of national spatial database at the scale of 1 : 50 000, a novel method for automatic detection of the spatial conflicts based on the plane sweep algorithm was proposed. By this method, the topological relationships between line segments were calculated in the plane sweep process. And the line-line topological relationships were deduced based on that of line segments. Then the spatial conflicts were detected according to the line-line relations and defined rules. The high efficiency of the algorithm has been approved by checking the spatial data quality of national spatial databases at the scale of 1: 50 000. |
| Keywords: | GIS spatial database updating spatial conflict plane sweep algorithm calculation of spatial relations |
