I am currently taking an online course on GIS and had a question about spatial joins. The course's example project is finding out which watersheds are in each county - there is a county feature class and a watersheds feature class. They describe their method as wanting to take attributes from counties to apply to watersheds so they have selected watersheds as the Target Feature and counties as the Join Feature.
I am working on a different spatial join exercise, this time involving finding precinct voting information per county. I am working with a precinct voting feature class and a county feature class.
My project only seems to have the ideal outcome when taking attributes from the precincts and applying it to counties, i.e. having counties as the Target Feature and precinct votes as the Join Feature.
I was wondering why that is, when the course example uses counties as the Join Feature?
