I have 7 shapefiles over an agricultural area. All of them have the same attributes (province code, polygon code, crop, etc.). I want to combine them to have only 1 shapefile. I have used the "union" tool of QGIS. The result looks good but the attribute table of the output is not what I want.
This tool copy and paste each input attribute table so in the output table there area a lot of duplicates. Is there a way to have only one time the colums and then all the values?
As you can see in the image, attributes like "ID_RECINTO" are duplicated.
