摘要
空间自相关度量的基础是空间权重矩阵的生成,而人工建立空间权重矩阵是一项耗时且计算量大的工作,因此需要解决空间权重矩阵的自动生成问题。本文以ArcObjects为空间目标的管理工具,利用VB可视化编程环境,研究了空间权重矩阵的自动建立方法。实验结果表明,该程序具有较好的健壮性和可执行性,可以成功的应用于空间统计分析模块的计算中。
The constitution of spatial weight matrix is the basis of measuring spatial autocorrelation.Using manual method to constitute spatial weight matrix is a time-consuming and calculative work,especially when the data set is very large.So it's necessary to solve the auto constitution of spatial weight matrix.In this paper,the authors take ArcObjects as the management tools of spatial objects,make use of the visual programming environment of Visual Basic,research on the auto constitution of spatial weight matrix.The experiment result indicates that the procedure is robust and performable,and can be successfully applied in the calculation of spatial statistical module.
