I am trying to convert the Corine Land Cover Map (version CLC18) from .gdb format to .shp. I am working on QGIS. I tried Export>Save Feature as>ESRI Shapefile but it didnt work. The log file with the errors lives here: https://pastebin.com/8QiKw6nj Any ideas?


Also tried using OSGeo4W with C:\>ogr2ogr -f "ESRI Shapefile" F:/n F:\DownloadsFromExplorer\clc2018_clc2018_v2018_20_fgdb/CLC2018_CLC2018_V2018_20.gdb . The error log file: https://pastebin.com/1Vypvr1f

    Please share your errors and describe the way how does your initial shapefile look like with us.

  • The initial file is in .gdb format.

    Seems like shape_length and shape_area fields are causing problems. Uncheck them in the export dialogue. They are not needed (or can be recreated later.)

    It seems that you have quite a large dataset and the size of the resulting shapefile exceeds the 4 GB limit ERROR 1: Failed to write shape object. File size cannot reach 4294960868 + 11320.. 4 GB is special for GDAL, the normal max limit is 2 GB. Use GeoPackage as outputformat instead.

The CORINE Dataset is a pretty big dataset with some long fields in the attribute table. The old and clunky shapefile can't handle both of these very well (at all).

See for example: SwitchFromShapefile

So if you do not really need it as a Shapefile for a specific workflow, which can't handle .gdb or even better .gkpg, then you can try what @BERA suggested. Otherwise I would strongly suggest to stay in .gdb or .gpkg because this type of file is really quite unsuitable for the shapefile format.
