I'm trying to figure out how others have implemented a ranking system that allows them to control which zoom levels a city displays on, specifically in regards to GeoNames city data, as there is no preexisting field that provides this type of information.
To be clear, I'm talking about a numeric field that specifies which cities display on each zoom level. I'm trying to determine the best way to assign the numeric values.
The city data provided by Natural Earth includes a scalerank that can be joined via geonameid, but there are only ~7000 cities and that doesn't cover the entire GeoNames dataset, which therefore makes it insufficient.
I devised my own method that is based on population and proximity, and may soon incorporate political capital status, but I would really like to know what others have done before I continue.
Any and all input is much appreciated. Thank you in advance!
