Spatio-temporal Visualization Method of Spatial Interaction between Regions

  • Received Date: 05 Jan 2009
  • The existing visualization methods for spatial interaction between regions lack comparability and are limited by time points.In order to overcome these shortcomings,a spatio-temporal visualization method of spatial interaction between regions was proposed.In this method,the center point of every region is taken as the centre point of its visualization result,the total spatial interaction between regions and the spatial interaction between regions at different time points are calculated respectively to determine the radius and angle of visualization results by using the spatial interaction model.By taking the seven regions of Sichuan Province as research objects,the spatio-temporal visualization of spatial interaction between regions was realized.The experimental results show that this method is of high legibility and comparability.
