QGIS - How to correct the geometry of overlapping polygons in the same layer

[@jakubfuska244]

guys, i love you!!! If i have seen this video in the past, my projects would be lotta easier :) thanx!!!

[@WebStoryMap]

Thank you and good work!!!!

Merci pour cette vidéo un bon travail.Pouvez -vous nous montrer aussi comment détecter et corriger la géométrie des polygones qui se chevauchent dans des couches différentes

[@HDcame]

Is it possible to offset only overlapping lines? For example buslines, which have similar routes.

[@WebStoryMap]

The command used relates only to polygonal elements. For linear elements you should perhaps work on "Delete duplicate geometries" or "Select by position".

I tried this out with several different shapefiles and get always the same error after the algorithm is executed: "The following layers were not correctly generated. C:/.../INTERSECT.shp"
When I go to this directory, the only file that it generates is the .prj extension. Do you have any idea of what could be causing the issue?

[@WebStoryMap]

Hi, try saving not the shapefile but choose the option 'save to temporary file' as I did in the video.

[@mkbls1992]

@@WebStoryMap thanks for your quick reply! I was already using the temporary file option.

@@mkbls1992 Try correcting the initial shapefile with 'Correct Geometries', which can be found in the 'Processing Toolbox', otherwise send me the file I'll try to check it.

'Fix the geometries' is the correct command

[@mkbls1992]

@@WebStoryMap I fixed the geometries and it worked! Thank you so much!

VERY VERY GOOD!!!! THANK UUUUUUUUU!

[@MargaretAyoola]

thank you for this. but i am having an issue, whenever i merge, the ID results gives 0

[@WebStoryMap]

Maybe you didn't write the function text correctly. I bring you the code for the functions.
if(regexp_match("ID",'\\|') > 0, regexp_substr("ID",'[^|]*'), "ID")
if(regexp_match("ID",'\\|') > 0, regexp_substr("ID",'(?

[@simoneridolfi2877]

thank u!!!!!!!

[@TikTok-ds7fe]

why? i did like you show everything but it doesn't work, pleas

[@WebStoryMap]

Have you checked that the function has been written correctly? If you look below in the comments you will find the text of the function.

Hi I thought this was just what I needed but the input text gave me 2 syntax errors even after checking 3 times.

[@WebStoryMap]

if(regexp_match("ID",'\\|') > 0, regexp_substr("ID",'[^|]*'), "ID")

[@WebStoryMap]

if(regexp_match("ID",'\\|') > 0, regexp_substr("ID",'(?

[@AkkiKumar-ft1xo]

I want the code
