随着人们对空间信息的需求,近年来对不完备空间数据的研究日益广泛,空间不完备数据填补问题备受重视。在实际应用中因不能充分利用数据所包含的信息,导致填补后的数据误差很大。针对这个问题详细阐述了空间不完备数据的检测和填补方法,重点介绍了基于克里格插值法的空间数据填补方法。最后用实验证明了克里格插值法恢复不完备空间数据时的精度最高。
With the demand of people for spatial information, the research of incomplete spatial data has been more and more extensive in recent years, and the problem of filling the incomplete data in space has received much attention. In practical applications, the information contained in the data can not be fully utilized, resulting in a large error in the filled data. Aiming at this problem, the methods of detecting and filling the incomplete data in space are expounded in detail. The method of filling spatial data based on Kriging interpolation is introduced emphatically. Finally, experiments show that the accuracy of the Kriging interpolation method when restoring the incomplete spatial data is the highest.
