Hello, I am preparing a talk to introduce new mappers to OSM. I want to provide them some guidance as to what general things we map and don't map. The beginners guide provides much of this. One thing that is not addressed is the mapping of temporary features/conditions. It seems common sense to me that we don't map very temporary things, such as cars in parking lots or snow cover (unless it is a year-round snow field or glacier). However, I cannot find anything on the wiki that explicit states this.
I did read the wiki page for the crop=* key[1] which states "it is recommended that this tag only be used for areas where the same crop is repeatedly (e.g. grown year after year). Otherwise it is easy for the value to become inaccurate in OSM." This seems to support my point, albeit only for the specific case of crops. I also read the wiki page on the temporary:date_on=* tag[2] which seems to suggest some temporary things can be mapped, but they should be tagged as such. A) Is there agreement to generally not map most temporary features/conditions? B) Is this explicitly documented on the wiki? Can someone provide me a link?
