    Research on voxel-based land complex modelling and adaptive resolution expression methodology by D. Sun, T. Shen, L. Huo, F. Kong

    Published 2025-08-01
    “…In order to improve the efficient use of land complex resources, explore the application of voxel model in land complex change monitoring, and propose a voxel-based land complex modelling and adaptive resolution expression method for the problem of large data redundancy and poor expression effect in the dynamic expression of land complex voxel model.Firstly, voxel classification and stratification are carried out through element characteristics to determine the elements suitable for voxel modelling; then, based on the analysis of terrain factors, the adaptive resolution expression method is constructed by optimizing the node evaluation criterion through the comprehensive consideration of sight distance and comprehensive terrain complexity.The results show that the method in this paper can achieve efficient expression and smooth scheduling of land complex voxel models at different resolutions, thus significantly reducing the computational complexity while maintaining the expression accuracy of important features.…”
