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

  1. We had a few use of man_made=graduation_tower. No use foramenity=graduation_tower; building=graduation_tower; man_made=thorn_house.
  2. We have an unclear use in stub articles of graduation towers on the wiki, so many of graduations tower are onlytourism=attraction (e.g. node 4095375179, area 1000050489, node 8420864847);building=yes (e.g. area 373881180; area 923748887) or amenity=fountain (e.g. area 525327281; node 7536427323; area 532557236)
  3. man_made=graduation_tower would be the main tag for these places; brine_source=* would describe the place from which the brine is obtained

Why graduation tower?

  1. 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);
  2. We can find "brine graduation" process in a few dictionaries (A Dictionary of Chemistry and Mineralogy; Dictionary Geotechnical Engineering) or in science (ResearchGate);
  3. 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";
  4. This term won on voting for the proposal tag in OpenStreetMap Community

Tagging

Create a node node or an area area, tagged with man_made=graduation_tower.
