Afternoon all,<br>
I have a slight issue, there are a number of MapInfo Tab Files which
we want to convert to Shapefile, but they do not convert correctly.<br>
The issue arises with Rings/Holes in the Polygons, when you save the
TAB file as a shapefile, some of them are not displaying correct,
they overlay the hole as another polygon.<br>
The issue seems to be related to the direction the hole was
digitised/generated to. The issue can also be replicated outside of
QGIS by running ogr2ogr, so it seems to be a GDAL/OGR ESRI Shapefile
Driver issue.<br>
Now in saying all that, QGIS 3 seems to be able to fix the issue by
running, <i><b>Fix geometries </b></i>from the Processing
Toolbox.<br>
My question is, Is there a way to fix the OGR Driver to fix the
issue, or a tick box under <i><b>Save Vector Layer as... </b></i>to
run/implament the <i><b>Fix geometries </b></i>tool as part of the
save process?<br>
This is an issue, which pops up regularly online, with no solution
to date.<br>
Regards & Thanks in advance.<br>
