Data Import Export Supported Formats
When performing GIS processing, in addition to using SuperMap's own data formats, it is also necessary to operate on various external data formats. The data import and export functions provide mutual conversion between different data formats, effectively supporting multiple data formats.
The following lists the data formats supported by data import and data export for user convenience.
1. Vector File Import/Export Support
