ARC/INFO动态视点分析并行处理研究

Parallel Process of Active View Analysis on ARC/INFO

RC/INFO动态视点分析是动态观察分析地形图上某条路线的地形特点 ,该路线是以用户所选取的临界点为基础形成的 .分析了飞行路线的特征 ,并通过一定的算法模拟了与所选路线相似的曲线 .根据并行处理的需要在曲线中插入新的临界点 ,以临界点为基础进行任务分配 。

The function of active view analysis on ARC/INFO is surveying land form features of a selected fight line. The fight line is generated by critical points that the user selects. In this paper, the author analyses features of the flight line and simulates the curve similar to the flight line through an algorithm. Because dispatch task of parallel process is on the basis of critical points, the curve must be inserted new critical points that divide the curve evenly. This method keeps the balance of task dispatch and has better parallel effects.
