Abstract: On the semantic and spatial query demand of GML data, Tap the GML data characteristics, and the traditional spatial data indexing techniques and XML data indexing analyzing, the paper designed structures and algorithms of GML holistic index (EKR+:Extend K-Means R+), which based on geographical feature units joints extended regional codes and geometric attributes for the key index, On the side, Based on EKR+ index designed the semantic and spatial join algorithm. Finally, performances study show that our techniques outperform the more traditional approach.
Keywords: Path index, Extended-regional code, GML holistic index, Semantic and Spatial Query
