moving range query

基本解释

By using the grid index built for multiple queries, a multithreading continuous multiple range query algorithm is proposed based on uniform partition of the moving objects in memory.
提出了基於移動對象數據均勻劃分的多線程連續多範圍查詢処理算法，該算法以爲查詢建立的格網索引爲基礎。
In a user defined time interval, the predictive continuous range query continuously returns moving objects that will appear in a spatial query range during a future temporal query interval.
預測性連續時空區域查詢在用戶指定的時間範圍期間持續地返廻給定未來查詢時間範圍期間將出現在查詢區域的移動對象。
