Yes, converting GML to DGN uses lossy compression, which reduces file size by discarding some visual data. Set quality to 85-95% for a good balance of quality and file size.
DGN files are typically 50-80% smaller than GML files because DGN uses efficient lossy compression. The exact reduction depends on quality settings.
GML (Geography Markup Language) is the OGC standard XML grammar for encoding geographic features with full coordinate reference system support.
DGN (Design) is the native file format of Bentley Systems MicroStation, used for storing CAD drawings and GIS data in infrastructure projects such as roads, bridges, and utilities, supporting 2D and 3D design elements with level-based organization.
