摘要
在自然界中大多数现实世界的实体都是动态的,地图上的公路、铁路、居民地等只是相对于一个很短的时间里是静态的,经过一个长的时间这些实体都将发生改变。本文根据不同时态地理实体的各种特征比较,将两个时态的数据进行关联,建立几何、位置和属性的变化模型,将这个动态的过程表现出来。试验表明,本文的算法是有效的。
Most phenomena in the real world are dynamic in nature,thus the term static can only be used for objects such as cartographic roads,railways,residential area,etc,that may not change in a short period of time,however,all of these objects will change during a long period of time.Based on the comparison of several characteristics of mutil-temporal geographic entities,we associate the data of two versions and establish a model which has variation in geometry,location and property,and visualize the dynamic process of this model.Experiment proves that the algorithm is effective.
