Merge shapefiles in order

by MrXsquared   Last Updated November 27, 2017 09:22 AM

How can I merge shapefiles in a special order in QGIS? What I have and what I need to be merged in that order:

what i have

What happens when using merge by mmqgis:

merged by mmqgis

As u can see not usable at all. Attributes are gone.

What happens when i use "merge shapefiles" tool by qgis:

merge shapefiles by qgis

As u can see some time zones are covering smaller time zones. So i tried to order them by using mmqgis again:

sort merged shapefiles by qgis by mmqgis

Attributes are ordered now but geometry is still overlapping.

Is it possible to merge shapefiles in a special order using qgis respectively to sort their geometry afterwards?

You need to use Union Tool from Vector -> Geoprocessing tools -> Union. This should give you the correct topology. Or, you can use difference tool repeatedly to get the difference between big polygons and smallers polygons and finally use Merge tool to put them in one polygon shapefile.

But Union will solve the problem.
