TSC-IRNN: Time- and Space-Constraint In-Route Nearest Neighbor query processing algorithms in Spatial Network Databases
收藏 引用
IEICE TRANSACTIONS ON INFORMATION AND SYSTEMS 2011年 第6期E94D卷 1201-1209页
作者: Kim, Yong-Ki Chang, Jae-Woo Chonbuk Natl Univ Dept Comp Eng Chonju 561756 Chonbuk South Korea
Although a large number of query processing algorithms in spatial network database (SNDB) have been studied, there exists little research on route-based queries. Since moving objects move only in spatial networks, rou... 详细信息
