Embodiment Construction
[0032] Such as figure 1 , for realizing the flowchart of the three-dimensional modeling method of building inside and outside integration in digital map, this method is carried out as follows:
[0033] Step 1, building data files:
[0034] Collect the CAD drawings of building construction in the target area, and put the CAD drawings of the same coordinates into the same named folder; in this embodiment, the CAD drawings of Tianzheng Architecture are collected, and the CAD drawings are derived from the planning and construction project data, such as the approved Documents, general plans, construction drawings, etc. When building a file, the construction drawing data is the basis, and the planning application documents and table data are auxiliary.
[0035] The following is an example of the construction application data for construction project planning permits.
[0036] A. Building construction drawing CAD data
[0037] The CAD data of the planning report generally provide...
