Here is my scenario:
I am trying to use Union to combine the land and mangrove shapefiles in QGIS and to compute for the areas of each individual geometry.
What I did:
First, I cleaned them. Upon checking the attributes, it appeared that there are duplicate features in the mangrove.shp,so I used 'Delete duplicate geometries' in the Processing Toolbox. I used Union to combine the land and mangrove shps,and again, some of the geometries were duplicated, so I repeated the process of deleting the duplicates.
Is it already ensured that the individual features have their individual attributes, or do I still have to use Multiple Parts to Single Parts?
