Thanks Joseph Eisenberg! That's exactly what I'm looking for. Good answer. So basically the primary use case of an **unnamed** residential, commercial, industrial, and retail "Zones" is not to convey (additional) information but to serve as a good-enough styling solution about what the zone conveys? As I suspected, it is solving a spatial clustering problem manually to achieve a good-enough different visual style. I guess you can see here in the landcover.
https://github.com/gravitystorm/openstreetmap-carto/blob/cae2309efd4ee0338fcdf9f201e92f20b338426c/style/landcover.mss#L16 The next question is can this be defined such that this can be automated? It would seem to me like if we, 1. Take a bounding box. 2. From that, subtract out the landuse polygons for named zones, LEAVING ONLY "unnamed zones, and land not in a zone." 3. From that, subtract out the landuse polygons for zones NOT of type "common landuse key values - developed land", per the wiki https://wiki.openstreetmap.org/wiki/Key:landuse LEAVING ONLY "unnamed zones of developed land, and land not in a zone." 4. Subtract out by key:highway lines LEAVING ONLY "unnamed zones of developed land and land not in a zone that does NOT intersect a highway." 5. Extract "unnamed zones of developed land and land not in a zone that does NOT intersect a highway" into a zone set. 6. Infer from the contents of the polygon what type of developed land the zone is. This would allow us to be precise and objective and determine what kind of "developed land" an unnamed zone was, as well as to provide a gauge of the accuracy of the zone. If this was done, do you think this would satisfy all use cases of unnamed landuse zones for developed land like commercial, retail, residential, educational? (I said in the above "unnamed zone" for simplicity, and unnamed zone can still have an operator, and in every case when I said unnamed zone, I meant a zone without a name or an operator). -- In the event this email pertains to Real Estate, Texas law <https://texreg.sos.state.tx.us/public/readtac$ext.TacPage?sl=R&app=9&p_dir=&p_rloc=&p_tloc=&p_ploc=&pg=1&p_tac=&ti=22&pt=23&ch=531&rl=20> requires all license holders provide to prospective clients the following forms: Information About Brokerage Services <http://docs.evancarroll.com/realestate/iabs.pdf>, Consumer Protection Notice <https://www.trec.texas.gov/sites/default/files/pdf-forms/CN%201-2.pdf>.
