Spatio-Temporal Data Model in Cadastral Information System Based on Weighted Graph

    Graphical Abstract
    • Abstract
  • A new spatio-temporal data model based on graph theory is presented,the organizing strategy of spatio-temporal data based on weighted graph is studied,and a formalized method to describe spatio-temporal semanteme is provided.The application foreground of transformation between different spatio-temporal data models is analyzed with the model.
