Description

Technical Field

[0001] This invention mainly relates to the field of model design technology, and in particular to a method and system for building multi-dimensional scenes based on BIM and GIS engines. Background Technology

[0002] With the rapid development of information technology, especially the widespread application of BIM and GIS technologies, many fields have begun to adopt these two technologies for more efficient and accurate planning and decision support. BIM is mainly used for building and infrastructure design, providing digital, visualized, and parametric design models of buildings; while GIS is used to process data related to spatial geographic information, effectively supporting geospatial analysis and environmental management. However, traditional BIM and GIS technologies have some limitations in the integration, analysis, and display of multi-dimensional data. For example, how to effectively combine monitoring data from different sources and achieve dynamic spatial and temporal display remains a problem to be solved. Existing systems cannot yet meet the needs of increasingly complex engineering projects in terms of data integration, scene modeling, real-time data updates, and dynamic display.
