Hi,
A friend of mine has a dirty input data set with lots of overlapping
geometries (within the same layer) and asked me if there is a tool
within QGIS to automatically remove the overlaps and assign the
overlapping area to the neighbor polygon with the largest area.
The solution was surpris
Hi Salvatore,
You could try:
1. Selecting/Highlighting Polygon 1, which should also highlight the area
you want to cut into area 4.
2. Using the Split Features tool, you can then create a cutline to clip
it successfully, something like what’s shown below in green, should work.
The
Hi Andreas,
You could do a ' self-intersect' of the polygon layer, calculate the area,
select polygons under specific area (assuming they're small overlaps) and
run the ' eliminate selected polygons' tool.
The GRASS tool v.clean offers some solutions too.
Greetings
Wouter

Hi Andreas,
the Algorithm "Eliminate selected polygons" was originally created to address
these questions. I usually imported the data into GRASS ran a clean there and
reexported the results into a non topolgical dataset. Thus overlapping areas
and gaps (only if closed) are identified and can b
Hello Richard,
it works!
Thank you!

I'm having issues trying to clip ecw images to a mask layer.

The tool runs extremely quickly (successfullyin 0.12 seconds), but produces a

this is the file the memorylayer saver plugin creates to save the temporary

I'm really dependent on the memory layer saver plugin, and have abandoned
