New here but I've been following the stack exchange for a while to get many answers on my newbie journey in GIS. I'm trying to find out how to merge different point in polygon classes by column.
Anyhow, I have a land use map of a neighborhood in Chicago. I used the parcel information to create a point map showing all the different land use classes (0-4). From there I went on to create 5 different layers, each showing the parcels of a certain type using new layer by selected features.
Next I did a points in polygon spatial analysis to let me know how how much each land use type exists in a certain block. So I have 5 layers showing me the point count per block - each layer shows a certain type. What I'd like to do is merge the columns. I know I can probably do it by editing the csv/dbf files associated with the shapefile, but I'd like to know if there's a way to do this through QGIS. Also, if you feel like I was inefficient in the way I went about this, please don't hesitate to critique my methodology.
