| 摘 要： | 动态分段是一种新的线性特征的动态分析、显示和绘图技术,极大地提高了GIS中线性要素的处理能力,然而,传统动态分段技术在处理具有时态性线性数据时却存在明显的不足。在对传统动态分段技术及其基本要素的探讨和研究的基础上,根据线性特征要素的类型分类,分别给出了顾及时间维的动态分段的数学表达;最后提出了利用时间-线路量度值图(TTD)空间描述时态动态分段的新方法。 |
| 关 键 词： | 动态分段 线性特征 GIS 时态动态分段 TTD |

| Abstract: | The dynamic segmentation is one kind of new technology with that linear feature can be analyzed,displayed and mapped dynamically.It enhances the capability of processing the linear element in GIS enormously.However,there is evident deficiency when the temporal linear data is processed by traditional dynamic segmentation technology.On the basis of the discussion and study on the traditional dynamic segmentation and its essential factors,the mathematics expressions of the temporal dynamic segmentation are presented separately according to the types classifications for linear features.Finally,the Time-Traversal Diagram(TTD) space is proposed as a new means to represent the temporal dynamic segmentation. |
| Keywords: | dynamic segmentation linear feature GIS temporal dynamic segmentation TTD |
