Embodiment 1
[0092] The existing rail station L4-6 (the 6th station of Line 4) serves residential building A, office building B, shopping mall C and park D around the station. Based on the collected traditional two-dimensional plane data and big data of TOD monitoring indicators, it is established that 2,273 residents belong to residential building A, of which 10% (227) residents travel through rail station L4-6; 3,000 employed people belong to office building B, 30% (900) of employed persons travel through rail station L4-6 and a series of mapping relationships and topological connection relationships.
[0093] Based on the above TOD logical relationship, use 3D rule fitting modeling to generate a large batch of refined 3D city models. Each digital spatial position in the 3D model corresponds to multi-dimensional attribute information and the first rule. For example, residential building A There are 8 households and 26 residents on the 12th floor; the 10th floor of the office building B c...

The invention discloses a rule-based three-dimensional geographic information model space analysis method, the method comprising: acquiring TOD monitoring indicators and data resources, and establishing an association relationship between the TOD monitoring indicators and the data resources based on the TOD logical relationship; The TOD monitoring index and the data resource are fitted in three dimensions to create a three-dimensional building model and generate a first rule; based on the first rule, adjust the first rule according to the TOD status assessment and expected goals, and generate The second rule is to adjust the three-dimensional building model according to the second rule, and implement actual intervention on urban space according to the second rule, and monitor the TOD urban big data after the intervention based on the second rule. This method can visually display spatial information, enhance multi-dimensional spatial analysis, and improve the efficiency of TOD city big data analysis.
Description
technical field [0001] The invention relates to the field of spatial analysis, in particular to a rule-based three-dimensional geographic information model spatial analysis method and system. Background technique [0002] In the prior art, the spatial information displayed by the 3D geographic information system is too abstract, and users cannot quickly and accurately judge based on the spatial information, resulting in low efficiency. [0003] Moreover, the analysis process of spatial information is often complex, dynamic and abstract. In the face of a large number, complex relationship and spatial information, the spatial analysis function of the two-dimensional geographic information system has certain limitations, such as inundation analysis, geological analysis, sunshine Advanced spatial analysis functions such as analysis, spatial diffusion analysis, and visibility analysis cannot be realized by two-dimensional geographic information systems, while three-dimensional ge...
