| 摘 要： | 一维(有效)时间区间(VT)和二维最小限定矩形(MBR)足移动数据基本的时空单元,两者性质不同,应用中也有差异.现有移动数据查询通常足将相关数据转换为高出原空间情形"一维"的空间数据,其优势在于可充分使用现有空问数据索引技术.文中主要贡献在于研究基于过去和当前时间查询的移动数据索引模式,该索引模式能够表征时空各自特性并...

| Abstract: | 1-dimension time intervals and 2-dimension minmum binding rectangles are the basic temporal and special units for moving objects daea(MOB).The present works on the indexes for MOB mainly transform special-temporal data into the pure special data which advantages are to use the existing techniques of special indexes such as R-tree enough.However,it is necessary to study the indexes which may describe the special-temporal chracteristics relatively inpendently and give the integration mechanism between time an... |
