摘要
采用属性加权的坐标拟合方法,分别推导出了空间点集分布轴线为直线和曲线的模型参数估计公式。 以MapInfo为平台和MapBaisc编程,对山东省胶济产业带分布轴线进行了实际计算和绘制。计算表明,本文方法 易于编制计算程序,计算结果具有客观性。
The parameter estimation of distributive axis equation of spatial point group is studyed in detail.Some formula for parameter estimation of distributive line and curve are derived.The distributive axis of Jiaozhou-Jinan industrial zone in Shandong Province is computed and mapped using MapInfo and MapBasic software system. The practice shows that the computation method is easy to program and its computation result is objective.
