  • 简介:大多数geospatial现象能被解释概率的联盟者因为我们不知道生物物理的过程和机制,那联合创造了并且观察事件。因为我们关于在在取样的地点的学习下面的现象肯定,这哲学是重要的,除了测量错误,,但是,在之间取样,我们关于现象怎么表现变得不明确。Geostatistical不确定性描述是以如此的一个方法产生随机数,他们模仿创造了存在样品数据的随机过程的结果。存在样品的这个集合被看作那个随机的功能模型的一条部分取样的认识。随机的功能的空间可变性被一张变量图或协变性模型描述。在他们的地点奖励样品数据,并且反映空间结构的认识到的表面需要由变量图模型确定了。他们应该各复制整个采样区域的样品直方图代表。这篇论文将由盖住univariate和指示物技术在随机的模拟考察基础希望他们在geospatial信息科学的应用将普遍、多产。
