The research on dynamic display model based on GIS

The majority of geography features has temporal attribute as well as spatial and other attributes and usually changes with time while the most of current GIS platforms are lack of the ability of dealing with space-time data. Dynamic display model advanced in this paper is the display manner which takes time as variable and visualizes the dynamic situation of geography features following time. The shape and position of geography features in the interim could be interpolated according to the given features. The features mentioned in this paper are 2-D polygonal shapes which are used to express area features in GIS. The combination of dynamic display model and GIS enhances the expression and analysis ability of GIS and provides the new approach to geographical research on temporal dimension.
