内蒙古自治区自然资源调查监测高精度实景三维建设方法与实践

High-precision 3D real scene construction method and practice for natural resources survey and monitoring system in Inner Mongolia Autonomous Region

自然资源调查监测体系构建需要统一的三维空间定位框架和数据分析基础。本文统筹内蒙古自治区地形地貌特征、区域经济格局和高质量国土空间体系目标,研究了分层、分级、分精度建设自然资源调查监测高精度实景三维数据底版的总体布局与建设方法,重点论述了地形级与城市级实景三维建设的技术路线、技术指标和实践结果。相关成果精度优于设计技术指标,已有效服务于内蒙古自然资源管理、城市国土空间监测、立体时空数据库建设等,推进了实景三维内蒙古建设进程。

The establishment of a natural resource survey and monitoring system requires a unified 3D spatial positioning framework and data analysis foundation.This paper takes into account the topographic features,regional economic pattern,and high-quality land and space system goals of Inner Mongolia Autonomous Region,and studies the overall layout and construction method of building a high-precision 3D real scene natural resource survey and monitoring data base by layering,grading,and different precisions,focusing on the technical route,technical indicators and practical results of the 3D real scene construction of the terrain level and city level.The accuracy of the relevant practical results is better than the designed technical indicators.The results have effectively served Inner Mongolia s natural resource management,urban land space monitoring,3D spatio-temporal database construction and other purposes,and promoted the construction process of 3D real scene Inner Mongolia.
