实景三维在自然资源调查成果可视化中的应用

Application of 3D Real Scene in Visualization of Natural Resources Survey Results

自然资源调查成果的三维立体可视化表达对实现各类自然资源的分析与应用具有重要意义。本文以自然资源综合调查监测国家试点一查多用子任务成果数据为基础,基于地形级实景三维提供的统一空间基底,以二三维一体化的系统开发技术为支撑,结合自然资源管理中的分析与可视化需求,开发了自然资源综合调查监测成果分析与展示系统,实现了多源数据的融合浏览、自然资源图斑的动态查询与实时渲染、自然资源体模型的模拟与查询、空间重叠资源的立体表达以及自然资源分类面积统计可视化,可以为加强自然资源的统一管理和开发利用提供有益助力。

3D and visual expression of natural resources survey results is of great significance to the analysis and application of various natural resources.Based on the results of the sub task of one survey multi-purpose use of the national pilot project of comprehensive investigation and monitoring of natural resources,based on the unified space base provided by the terrain level 3D real scene,supported by the 2D and 3D integrated system development technology,and combined with the analysis and visualization requirements in natural resource management,this paper developed the results analysis and display system of comprehensive investigation and monitoring of natural resources,which realized the fusion and browsing of multi-source data,the dynamic query and real-time rendering of natural resource patches,the simulation and query of natural resource volume model,3D expression of spatial overlapping resources and the statistical visualization of classified area of natural resources,and which can provide useful help for strengthening the unified management,development and utilization of natural resources.
