Positional uncertainty and attribute uncertainty have been commonly discussed in isolation and with no accounts for inner differences.
位置不确定性与属性不确定性常常不加区分地被看作是可以单个讨论的问题。
参考来源 - 位置不确定性与属性不确定性的场模型Due to the above line element error band model is based on the points are independent with each other and subject to multi-dimensional normal distribution, so the application of the location uncertainty model is limited.
3.由于以上线元误差带模型是基于空间中各点位置误差相互独立而且服从多维正态分布,因此在某些情况下限制了位置不确定性模型的应用。

之后通过增大信号发射功率,投放新的锚节点或投放新的普通节点,降低节点位置不确定性。

位置不确定性的图形描述为评价位置观测数据的质量提供了可视化的方法。
The graphical representation of positional uncertainty provides the assessment of the quality of positional data with a visual means.
因此，在GIS位置不确定性理论研究中，线状实体的位置不确定性理论关系重大。
So, positional uncertainty theory research of linear entity counts for much for GIS positional uncertainty theory research.
在GIS不确定性理论研究领域中，位置不确定性和属性不确定性是主要的研究对象。
