Optimization and scheduling of tile loading for three-dimensional model of land consolidation

doi:10.11947/j.AGCS.2022.20220115

Abstract

Abstract: As a national strategy, land consolidation is an important method to solve land use problems in the process of social and economic development in many countries. The function of land consolidation is to prevent the dysfunction or degradation of land space, which is significant in promoting the construction of ecological civilization. With the advancement of China's industrialization and urbanization, the contradiction among production,living and ecology has become increasingly prominent. As a key solution, land consolidation projects have been carried out extensively throughout the country, especially based on 3D visualizations technology. However, due to the large volume, complexity and fragmented characteristics of the data, the 3D visualization data storage and loading is too difficult to improve the application of 3D model in land consolidation. This paper supposed storage structure optimization method, model fragment loading optimization method and model scheduling optimization method, validated the methods through experiments and application demonstration. The validation and application proved that the proposed method can effectively support the 3D visualization related business in land consolidation projects.

Key words: land consolidation, 3D visualization model, 3D data processing, methodology research
