Then, in order to ensure the security of the CAD data, it is necessary to determine whether the current user has the right to acquire the CAD file according to the role information of the user and the right information of the CAD file, thereby determining whether the CAD file can be acquired. If yes, each layer file corresponding to the CAD file is selected, and then each layer file is loaded into a workbench of preset geographic information system software. In one embodiment of an application scenario in the present specification, when a CAD file is loaded into preset geographic information system software, first, a CAD data ready to be loaded is imported into an arcMap tool, then, by selecting a layer, data is selectively added to the arcMap tool, and the CAD data is loaded into a workbench, and if the CAD file is a plurality of CAD files, the above operations are repeated.
S102: and performing dimension reduction processing on the CAD data in the CAD file based on the preset geographic information system software to obtain effective CAD data of the effective data layer.
In order to reduce the processing pressure of invalid data transmission on memory calculation, in the embodiment of the present disclosure, the CAD data shown in fig. 2 in the CAD file is subjected to dimension reduction processing according to preset geographic information system software, so as to obtain valid CAD data of the valid data layer, and then subsequent analysis processing is performed. Specifically, in one or more embodiments of the present disclosure, the dimension reduction process is performed on CAD data in a CAD file based on preset geographic information system software to obtain effective CAD data of an effective data layer, which specifically includes the following procedures:

And determining whether to perform data cleaning by determining whether the data attribute matched with the current work task is consistent with the data attribute of the CAD data in the effective format. If not, the valid format CAD data is deleted to obtain filtered initial presentation CAD data as shown in FIG. 4.
In addition, in an embodiment of an application scenario in the present specification, after a layer to be processed is selected, a data format of all data in an attribute table is obtained, and then corresponding data attributes can be obtained through editing information, and batch selection is performed on the data according to the attributes.
