I would like to split a shapefile made up of approximately 8200 elements into five having an equal number of elements. I don't want to base this division on an attribute. There is a simple way to do that in QGIS?
You can create a new attribute field which bins the 8474 elements into 5 bins:
bin_size = 8474/5, or approx. 1750 elements per bin.
Go to field calculator and generate a new integer field called 'bin' with this expression:
If you want it to be more dynamic, you can do this, which uses the size of the table as a parameter for the number of elements per bin. Replace 'fid' with the name of a different field if your table doesn't have a field named fid.
Then use bin as the field to split by in the Split tool.
