Proposal
Graduation towers are structures used in the production of salt which remove water from a saline solution by evaporation, increasing its concentration of mineral salts. The tag can be used on nodes (as POIs) and areas.
The mineral-rich water droplets in the air are regarded as having beneficial health effects similar to that of breathing in sea air.
Rationale
- We had a few use of
man_made=graduation_tower. No use foramenity=graduation_tower;building=graduation_tower;man_made=thorn_house. - We have an unclear use in stub articles of graduation towers on the wiki, so many of graduations tower are only
tourism=attraction(e.g. 4095375179
4095375179, 1000050489
1000050489, 8420864847 8420864847);building=yes(e.g. 373881180 373881180; 923748887 923748887) or amenity=fountain(e.g. 525327281 525327281; 7536427323 7536427323; 532557236 532557236) man_made=graduation_towerwould be the main tag for these places;brine_source=*would describe the place from which the brine is obtained
Why graduation tower?
- One of the meangings of the terme "graduation" is "The exposure of a liquid in large surfaces to the air, so as to hasten its evaporation." (it's the definition in en-Wiktionary);
- We can find "brine graduation" process in a few dictionaries (A Dictionary of Chemistry and Mineralogy; Dictionary Geotechnical Engineering) or in science (ResearchGate);
- We don't have to change "graduation tower" (which exist, and it's also on en-Wikipedia and most of sources) to "osm specific terme";
- This term won on voting for the proposal tag in OpenStreetMap Community
Tagging
