Urban safety planning design method for synchronously operating GIS platform and CAD platform

The invention relates to the technical field of space planning, in particular to an urban safety planning design method for synchronous operation of a GIS platform and a CAD platform, which comprises the following steps: determining a comprehensive coordinate conversion model; calculating conversion parameters; automatically converting the coordinate system result into a corresponding coordinate type according to the metadata configuration table of the source coordinate and the target coordinate; performing conversion precision evaluation; checking the conversion quality; cAD graph attribute information management and CAD data integration management are carried out. According to the method, CAD and GIS file mixed graph adjustment of a server side can be achieved according to a one-graph coordinate positioning mode, the functions of attribute query, index statistics and the like can also be achieved, the method can be combined with a project management system and planning and compiling design software, compili
