    Studies on Technology of Multi-Resolution Land Model Based on Geographic Features in Visualization of 3D GIS

      Graphical Abstract
      • Abstract
    • The simplify criterions for construction of multi-resolution models was discussed based on geographic features. For the problem about carck brought out in model triangularization, a new technique combining quad-tree has been invented.
