GDB (GDB) - ESRI File Geodatabase, folder-based spatial dataset. Best for enterprise gis data management, esri ecosystem spatial storage.
DGN (MicroStation DGN drawings) - Bentley MicroStation CAD/GIS hybrid design file. Ideal for civil engineering, infrastructure mapping, transportation gis.
Yes, GoConvertFile offers free conversion of GDB to DGN for files up to 100MB. No registration required.
Most GDB to DGN conversions complete within seconds for standard-sized files. Larger files may take longer depending on the conversion complexity.
DGN is ideal for civil engineering, infrastructure mapping, transportation gis. Bentley MicroStation CAD/GIS hybrid design file
Yes, converting GDB 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 GDB files because DGN uses efficient lossy compression. The exact reduction depends on quality settings.
ESRI File Geodatabase (GDB) is a collection of files in a folder structure that stores vector feature classes, raster datasets, topology rules, and network datasets, serving as the primary geospatial data storage format in ArcGIS.
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.
