MapInfo tab files with LargeInt can't be converted to QGIS or any other format

Question

I am trying to convert a MapInfo tab file with ogr2ogr

I did this:

ogr2ogr -f "ESRI Shapefile" testing.shp TEST.tab

And get this error;

ERROR 3: Failed to parse field definition at line 8 in file TEST.tab

    FAILURE:
    
    Unable to open datasource `TEST.tab' with the following drivers
    oid LargeInt ;

QGIS gives me this error when adding a vector layer:

Invalid Data Source: C:\Temp\Struer\TEST.TAB is not a valid or recognized data source.

I tried this:

Change the LargeInt to Integer in MapInfo. 

Then it works fine.

So it seems like there is a problem with the LargeInt type.

Is it GDAL that can't handle this or does anyone knows a workaround?

Answer 1

There is a GDAL plugin available here that adds support for the Extended MapInfo TAB format.

Answer 2

GDAL's mitab module indeed does not know about the LargeInt type.

Until that support has been added to GDAL, you have to use a different type.

Answer 3

This will be available in GDAL 3.7.0 (May 2023) per https://github.com/OSGeo/gdal/pull/7165.
