Abstract: The multi windows technology for monitoring multi objects simultaneously is introduced. The effective view link list method of controling and managing the overlapped multi windows is given, which can make overlapped multi windows display electronic maps and real time moving objects. The complexity of algorithms is decreased, for the problem of two dimension space is changed into that of one dimension space. Four algorithms, that is, the straight line segmentation algorithm, the finding rectangle intersection algorithm, the finding rectangle difference algorithm, and the creating view link list algorithm, are given.
