Study on spatio-temporal data model for moving object trajectories
Shan Guo-hui · Cehui kexue · 2007
The trajectory of moving objects is an important information source of spatial information system. Only by managing and utilizing it efficiently and reasonably, can people understand and control the multi-dimension and dynamic environment. The status of current study of moving objects is introduced firstly. Then the key technologies about moving objects modeling, storing, querying, indexing and visualization are analyzed and a solving project is put forward. Finally the management and application of entire process of moving object is realized successfully.
