摘要 分析了导航地图数据增量更新过程的时态特征,通过应用时态GIS实现了增量更新过程的建模,提出了基于历史跨度的时空数据模型(history span based temporal-spatial model,HSBTM)。在此模型的支持下,推导了增量数据的计算公式,论述了历史跨度时空数据模型的简化表达和实现方法。 According to the requirement of quickly dynamic update of navigable digital map , the principle of navigable digital map increment update is addressed. Temporal characteristic of increment update process is analyzed and modeling of increment update process is also realized. A history span based temporal-spatial model (HSBTM) is put forward; and based on this model the increment data calculation formula is deduced; finally, the simplification expression and realization method of HSBTM are discussed.
