Line Segment Nearest Neighbor Query of Spatial Database Based on R*S-Tree

Autor: Yan Rui Li, Xin Cai Kang, Dian Zhu Sun, Yong Wei Sun

Publikováno v: Advanced Materials Research. :194-197

An algorithm for nearest neighbor query of Line Segment based on the R*S-tree is proposed. The dynamic spatial indexing structure for spatial line segments was constructed based on the R*S-tree, and the k-nearest neighbor of the target line segment w
