At present I have a dataset which is broken down by Electoral Divisions (circa 3,500). However, due to issues with some of my variables I need to choose a larger spatial unit - Local Electoral Area (LEA). An LEA is an aggregation of a number of different Electoral Divisions. The issue with the LEA shapefile, is the attribute table does not provide a lot of information of the region.
What I would like to do is aggregate my various Electoral Division variables to an LEA level. However, I believe this will be extremely difficult. Instead what I would like to do is join by ED's by LEA so I'll know what ED is in what LEA. The issue here is at present I have no identifier which is common between both shapefiles.
I originally was going to geocode by Electoral Divisions and than merge them to the LEA shapefile, however, 3,500 is quiet an amount, as well as ED names are quiet common with other areas in the world.
Is there some way to overlay the two shapefiles so my ED's are imbedded within the LEAs. Both shapefiles are working of the same coordinate system, so I imagine this is possible?
I'm using QGIS
