In the process of data format conversion, firstly, the geometric type is judged according to sdo _ gtype in geometry. sdo _ gtype may be 2001: dots, 2002: lines, 2003: faces. Then, point data extraction, line data extraction and surface data extraction are performed. During the POINT data extraction process, the x, y coordinates in sdo _ POINT in geometry are transferred to the mif file, such as POINT 116.5477339.87347. In the process of extracting the online data, the PLINE number is output according to the number of shape points of the sdo _ ordinates calculation line in geometry, and then x and y coordinates of each shape point are written in sequence. In the process of extracting the surface data, the number of regions is output according to the number of shape points of the sdo _ ordinates calculation line in geometry, and then x and y coordinates of each shape point are written in sequence.

In addition, in this embodiment, the mif/mid file after transcoding may be distributed to a corresponding folder according to the correspondence between the directory structure and the file defined by the parameter f _ files column in the file directory template file conf _ data _ issue. After the mif/mid files are distributed to the corresponding folders, the product data with the directory hierarchy can be provided to the customer.

In addition, the above embodiments may also use the display style and color interface to electronically map the style and color of roads, buildings, grass, etc. For example, display styles may also be divided into three categories, namely:

1) dot, output format: symbol (1,2, color);

2) line, output format: pen (1,2, color);

3) the output format is divided into two types: lines in the face: pen (1,2, color), face-fill color Brush (1,0, color).

The processing flow of the display style and the color interface is as follows: firstly, judging which type the current processing belongs to, then extracting color data in the data and then outputting the color data.
