一种LAS数据快速调度方法

Quick query method in LAS

为了提高数据分类处理时对大数据量LAS数据的访问速度,算法充分利用点集凸包的概念,提出了一种新的建立索引和快速调度的方法。通过实验证明,该方法在完全保留LAS数据原始文件存储的基础上,调度速度得到显著提高,完全可以满足数据分类处理的需要。

In order to improve the access speed of classification process on large amount of LAS data, new indexing and fast scheduling methods which made full use of the concept of convex hull of point set were proposed. Experiments had proved that this method completely retained the original storage structure of the LAS file, the scheduling speed was significantly increased and the needs of data processing were fully met.
