And if you delete the .qix before saving? And then recreate it...

I already tried to save to anther shapefile and edit it (add, modify, remove features …) the .qix was automatically created and I get the same problem

 

Thanks,

Some users [1] have already encountered this issue and i understood that it may be related to non correspondance between the number of rows in the .dbf file and number of geometry (some rows had no geometry). A simple "Save As.." to another shapefile has solved the problem.

Hi,

 

Do you think that this problem is often caused by geometry problems?

 

Thanks,

Nejia

Hi,

Nejia, what about the validity of the geometry of your features? You can check with the tool in Vector menu > Geometry tools > check geometry validity

Hi all,

 

I load a shapefile, then I create a spatial index to maximize speed of zoom and navigate in the map.

The problem is: when I zoom to any area feature appear and other doesn’t.

And it seems To me that the spatial index is automatically created even when I delete the .qix file

 

 

Best regards,

Nejia
