Expression Model for Settlement Incremental Information

  • A new expression model for settlement incremental information based on spatial change type,dynamic update operation and graphic data delta is proposed for making up the deficiency of the current expression models,which are based on a single level feature.The relationships among spatial change type,dynamic updating operation and graphic data delta are extracted through the classification of spatial changes.The expression model of settlement incremental information is constructed.The experimental results show that this model is valid and effective.
