支持动态地理现象理解的运动要素地图表现

Map Representation of Moving Features for the Dynamic Geographical Phenomena Understanding

空间运动现象是动态地理现象的一种重要表现形式,该文从运动状态与历史过程的静态表现、运动过程生命期的顺序动态表现及目标运动过程的动态特征表现等方面,论述了运动系统中运动对象运动特征的地图表现问题。对于目标运动过程动态特征的地图表现,提出了运动实时动态特征中的方向关系、距离关系及拓扑关系表现问题与方法,并以船舶导航为对象给出了相应的实例。

Spatial motion phenomena are substantially considered as one form of dynamic geographical phenomena. This paper discusses the map representation methods of moving features in the motion system, which include the representation of motion states and historic processes in a static mode, and the representation of the sequences of motion processes＇ lifetime, and the representation of the dynamic characteristics of motion process. In detail, this paper clarifies the representation of dynamic characteristics of motion process, which is described as the real-time representation of orientation relationship, distance relationship, and topology relationship. Using the marine navigation system as experiment platform, this paper gives out some instances about the map representation of moving features.
