A three-dimensional map, a "booster" for the construction of Yunnan's data free trade

The Honghe area of China (Yunnan) Pilot Free Trade Zone relies on the Yunnan Geological Big Data Service Platform and based on the new generation of SuperMap 3D GIS technology, developed and constructed a digital free trade 3D map management system (hereinafter referred to as the "system"), which promotes free trade The construction of the management mechanism of "using data to speak, using data to make decisions, using data to manage, and using data to innovate" in the Honghe area of the pilot zone has realized the integration, digitization, informatization, and intelligence of natural resource management in the whole region and all elements. At the same time, the system gives full play to the role of "one map" of global natural resource data, strongly supports the scientific planning of departments at all levels in the Pilot Free Trade Zone, and improves the level of government management and decision-making.

Multi-source data fusion to build a 3D real scene

The system integrates high-precision terrain data and high-definition satellite remote sensing images to construct a topographic-level 3D scene of the Free Trade Pilot Zone, reflecting the real-world geospatial location and shape.

Terrain-level 3D scene

The system integrates oblique monomer models, orthophotos, rivers, etc. to build city-level 3D scenes, and uses real estate registration data as the base of the monomer model to dynamically query building information for refined expression and spatial statistical analysis to serve refined management .

City-level 3D scene

The system integrates BIM models, inclined single models, street lights, trash cans, billboards, manhole covers, underground pipelines, etc. to construct component-level real-life 3D scenes, accurately expressing the relationship between ground and underground integration, indoor and outdoor integration, and supports the integration of each component attribute query.

Part-level 3D scene

The system supports effect simulation and beautification of 3D scenes, and can simulate urban rain, snow and city night scenes in real time, bringing users into 3D scenes in an immersive way.

3D intelligent analysis, assisting urban planning management

Inundation analysis : According to the specified maximum and minimum elevation values and inundation speed, dynamically simulate the inundation process of the water level in a certain area rising from the minimum elevation to the maximum elevation, which is of great significance for flood control and disaster reduction, flood risk analysis and disaster assessment.

Inundation analysis

Visual area analysis : Based on a given observation point and observation range, analyze whether the observed object within the observation range is visible. The 3D visual field has important application value in the layout of natural resource survey and monitoring facilities.

Viewshed Analysis

Visibility Analysis

Excavation analysis : It is used to view the underground geological structure and underground pipe network structure, set the excavation depth according to the buried depth of the pipeline, draw the range for terrain excavation, and support attribute query. It is used for urban pipeline network management, which is convenient for checking pipeline leakage and damage, timely repairing and reducing disasters.

terrain excavation

Height limit analysis : According to the actual situation, combined with the requirements of the overall urban planning for the building height limit, the building height is limited. The 3D scene supports the visual expression of height restrictions, and has practical application results in urban master planning.

Height analysis

Used for auxiliary planning business analysis : first, quantitative analysis content, including the comparative display of building control lines, building density, floor area ratio, green area ratio, facility configuration, land use nature matching, and traffic and commuting conditions of two-dimensional spatial data. The comparison of the rationality of the quantitative analysis of the support project; the second is the qualitative analysis content, including the analysis of the conformity of the architectural texture in the three-dimensional space, the analysis of the city skyline and the sight corridor, the integration analysis of the form, color, volume and surroundings of the building, etc. , through an intuitive three-dimensional display method, it can better assist decision-making.

Ancillary business

Geological body analysis : Geological body explosion analysis can clearly and intuitively display the geological level distribution of complex geological blocks, so as to quickly understand the distribution of geological internal space or traffic flow. At the same time, it supports sectioning, excavation, drilling, etc. of geological bodies. Using the sectioning method, it is convenient and intuitive to observe the stratum structure of the anatomical plane. According to the needs, it can cut at any angle, and query the attribute information of the section in real time.

Multi-departmental sharing, empowering smart city construction

The three-dimensional one map is rich in data resources, three-dimensional and intuitive, and the high-precision model fits the real scene. In terms of the display and expression of spatial elements, the spatial information of natural resources is abstracted into three-dimensional entity information that is visible to human eyes and recognizable by machines. Its construction work runs through the stages of collection, management, coding, display and analysis of real 3D data, forming a three-dimensional space-time database covering all elements of mountains, water, forests, fields, lakes, grass and sand, which can be shared and applied to emergency management, Urban planning and design, smart city and many other fields.

For example, in terms of emergency management, combined with three-dimensional data to assist in the analysis of disaster impacts, the system can provide support for emergency rescue and decision-making command; in terms of urban planning and design, it can simulate urban planning and construction scenarios, and support custom layout of buildings and infrastructure in 3D Model, through the gradual sharing of data among various departments, helps digital twins and empowers the construction of smart cities.

The three-dimensional one-map system uses "three-dimensional space" and "entity code" to unify the natural resource data system and the bottom plate, fully and truly reflect the actual situation of natural resources and the natural geographical pattern, and better support the informatization, intelligence, and digitization of the Pilot Free Trade Zone In the future, AI image recognition capabilities and knowledge map construction and analysis will be included to help the construction of data free trade.
