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 happens when using merge by mmqgis:
As u can see not usable at all. Attributes are gone.
What happens when i use "merge shapefiles" tool by qgis:
As u can see some time zones are covering smaller time zones. So i tried to order them by using mmqgis again:
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.
Union will solve the problem.
