Surface element file conversion method and device, computer equipment and readable storage medium

[0043] figure 1 It is a flow chart of a surface element file conversion method provided in Embodiment 1 of the present invention, and the method includes the following steps:

[0044] Step S11: Obtain the first format area element file, and extract vector line data, label text data and road centerline data from the first format area element file.

[0045] In the embodiment of the present invention, the FME system can be operated by a computer device, and the first format plane element file can be obtained by using the FME system, that is, the user can input the first format plane element file into the FME system. Among them, the FME system is the Feature Manipulate Engine, a spatial data conversion processing system developed by Safe Software in Canada. By running the extraction application program in the FME system, the corresponding vector line data, label text data and road centerline data can be extracted from the first-format surface element file.

[0058] Step S21: Obtain the first format area element file, and extract vector line data, label text data and road centerline data from the first format area element file.

[0059] This step is consistent with the above step S11, and will not be repeated here.

[0060] Step S22: Perform preset vector line topology processing on the vector line data to obtain processed vector line data.

[0061] This step is consistent with the above step S12, and will not be repeated here.

[0062] Step S23: Using the processed vector line data to construct an initial area element, and superimposing the corresponding label text data and the road centerline data on the initial area element to obtain a new area element.

[0063] This step is consistent with the above step S13, and will not be repeated here.
