空间目标增量时空变化分类模型

Classification Model on Incremental Spatiotemporal Changes of the Spatial Object

  • 摘要: 增量发布模式的实现首先需要确定空间目标产生的增量时空变化,提出了一种层次化的增量时空变化分类计算模型,分别计算空间目标现实世界的整体状态差、空间目标数据库中的整体状态差、空间目标空间状态差,其中空间状态差的计算选择空间目标维数、尺寸、形状和位置4个测度。根据4算子取值集合确定单空间目标的基本增量时空变化,并通过组合基本增量时空变化构造单空间目标和多空间目标的复杂增量时空变化。

     

    Abstract: We detail the implementation of a new solution—increment transmittance mode, for the exchange of update information from the spatial data producers to the specialized departments. In order to transfer update spatial data with the increment transmittance mode, the incremental spatiotemporal changes of the spatial object should be confirmed. A new hierarchy model with four computing operators is proposed in order to self\|contained distinguish the incremental spatiotemporal changes of the spatial object. The model confirms the change types with the whole object delta of the spatial object, the size, dimension, shape and position delta of the spatial object. By computing results of the four operators, the basic changes of the single and multi\|features can be given. The complex incremental spatiotemporal changes can be composed based on the basic changes.
