[Platform Performance guaranteed by Instantiation and LOD Technology]
 

For the sake of performance requirements, SuperMap GIS USES LOD structure and instantiation technology to break through the visibility performance bottleneck of high-density models: LOD technology can select models with different degrees of precision according to the distance, which greatly alleviates the pressure of hill shading.The reuse model is realized by using the instantiation technology, and the rendering efficiency is improved significantly. 

[Powerful platform provides many practical functions]
 

In terms of practical functions, SuperMap GIS provides BIM with general GIS functions such as attribute query statistics, access analysis, sunshine analysis and indoor roaming, etc.Realized the BIM special function of simulating building construction process and specifying floor/component display separately;BIM coordinate transformation and BIM accurate matching with other spatial data are provided, which can meet the application requirements of the perfect combination of large scenes and fine indoor scenes.By comprehensively applying these functions in practical applications and giving full play to the advantages of GIS in location service and spatial analysis, BIM will generate practical and extensive application value.
 

Adhere to open a win-win concept of cooperation, BIM and 3 dgis cross-border integration market prospect is limited, can be used in urban planning, urban traffic analysis, indoor navigation, asset management, municipal pipe network management, the number of disaster prevention, emergency rescue, building, and many other areas, compared with their own individual application, the modeling, analysis, quality precision, decision-making efficiency, cost control levels have increased significantly. 

BIM+ Inclined photography to Promote the construction of smart city

Reviewing the tortuous road of building a smart city, we clearly realize that a single data and technology cannot achieve real smart services. The cornerstone of building a smart city is to realize complete digitization, which must be achieved through the combination of data and technology.With the progress of science and technology, the mature tilt modeling technology makes the tilt photographic model widely used, and its omni-directional and all-essential display of the physical world meets the needs of urban geospatial digitalization.As a fine model with accurate size and detailed information, BIM fills the gap in the micro field and realizes the digitization of urban interior space. 

Geographic information as an important information, the basis of intelligent city tilt photography technology scheme based on SuperMap leading the industry, 3 d GIS, puts BIM and tilt model under the same reference, formed from outdoor to indoor, macro to micro integrated geographical spatial scenes, organic combination of BIM and oblique photography model to speed up the pace of the wisdom urban construction, drink set a solid foundation for the spatial information. 

[BIM+ 3D Pipeline Construction of complete pipeline management system]

In 3 d digital factory district and municipal pipe network scenario, the earth, and all kinds of underground complex pipe network and equipment quantity is very large, given the unique advantages of BIM technology, design phase usually use BIM technology is comprehensive, three-dimensional pipeline with BIM technology on the scale of construction and mechanical and electrical equipment for real 3 d modeling, a comprehensive collision detection, arbitrary cutting and axonometric, determine a function such as, are helpful for the design and construction. 

After the project is completed and put into operation, a THREE-DIMENSIONAL pipeline management system will be built for operation and maintenance management.Based on SuperMap 2-D integration technology system, 3d pipe points, pipeline symbols and adaptive pipe point symbols are adopted for pipeline part to realize rapid construction of 3D pipe network scene.For ancillary buildings and mechanical and electrical equipment, the BIM model established during pipeline synthesis can be directly used.The combination of 3D pipelines and BIM model can quickly build a complete and real 3D pipeline scene. The 3D installation network analysis capability provided by 3DGIS can quickly search the upstream valve to be closed and analyze the affected area in case of pipe pipe explosion.Based on 3DGIS, it provides practical functions such as section inspection, excavation analysis, net distance analysis, collision analysis, connectivity analysis and so on, which can analyze and solve practical problems of pipeline management.
