moving range query

基本解釋

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(shù)據(jù)均勻劃分的多線程連續(xù)多範圍查詢処理算法，該算法以爲查詢建立的格網(wǎng)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(xù)時空區(qū)域查詢在用戶指定的時間範圍期間持續(xù)地返廻給定未來查詢時間範圍期間將出現(xiàn)在查詢區(qū)域的移動對象。
