Export GeoJson

Instructions for use

SuperMap iDesktopX provides the Export to GeoJson File tool, which supports exporting vector data to GeoJson files.

Function Entry

  • Toolbox->Data Export->Export Vector->Export to GeoJson.

Parameter description

  1. Source Dataset：
    • Datasource: Select the datasource where the data to be exported is located.
    • Dataset: Select the dataset to be exported.
  2. Result Data：
    • Result File: Set the file name for the export data.
    • Export Path: Set the directory for storing the export data.
    • Replace: This checkbox is used to set whether to overwrite existing files with the same name in the export path. If checked, it overwrites the existing file; if unchecked, the program cancels the export operation by default when overwrite is not set.
  3. Transformation Parameters：
    • Charset: The character encoding type used for the export dataset. To ensure the dataset displays correctly, use an appropriate character set. By default, ASCII (Default) is used for export. The most commonly used ASCII character set is suitable for Roman numerals and letters, utf-8 for simplified Chinese characters, and Unicode is used to meet the needs of cross-language and cross-platform display. For the list of character sets supported by the application, see Character Set List.
    • Filter Expression: You can set a filter expression to exclude objects that do not need to be exported, allowing only objects that meet the conditions to be exported. For how to use SQL expressions, refer to SQL Expression.
