地理动态图像是指用各种类型的图形符号来表达地理事物和现象的运动方向、发展趋势及动态变化过程的图像。动态图像着重反映的是制图区域内地理事物和现象的动态特征,其主要特点是时间序列为其不可缺少的要素。地理动态图像包括矢量动线图、动态曲线图、周期性规律轨迹图、符号扩展图及区域组合动态图等,其实质是地理事象动态特征的静态描述。
Geographic dynamic image refers to the use of various types of graphical symbols to express the geographical direction of things and phenomena of the movement direction, trends and dynamic changes in the process of the image. The dynamic images mainly reflect the dynamic characteristics of geographical things and phenomena in the mapping area. The main characteristic of the dynamic images is that the time series is an indispensable element. The geo-dynamic images include vector line diagrams, dynamic curves, periodic regular orbit diagrams, symbolic extensions and regional combination dynamic charts. The essence of geo-dynamic images is the static description of the geographical features.
