I have a dataset containing GPS coordinates and zip codes of locations from different regions in Spain, and I need to classify them as rural or urban based on either of these two information sets (and additionally having the city/town names based on these two).
I was wondering if anyone knows if there is any mapping (from zip codes or area names to rural/urban) I can find from a known, credible source, or if there is a way to classify these locations as rural or urban on my own if I have coordinates and/or zip codes?
Maybe if anyone can point me to a source that describes how this type of classification is typically done. For example, over here there is a mention of the classification that EU uses to classify as
'predominantly rural' and
'intermediate', but is there a simpler method?
