With about 11k occurrences (http://taginfo.openstreetmap.org/keys/industrial#overview), [1]industrial=* is mostly used for oil infrastructure but also for other sorts of industrial activities.
factory=* only occurs 569 times - with various values: http://taginfo.openstreetmap.org/keys/factory#overview [2] - I like industrial=* better because it covers more than factories. man_made=works dominates with about 83k occurrences: http://taginfo.openstreetmap.org/tags/man_made=works#overview [3] - its problem is that it requires an additional tag to describe its nature, such as product=* (1844 occurrences - http://taginfo.openstreetmap.org/keys/product#overview [4]) [5] or works:type (210 occurrences - http://taginfo.openstreetmap.org/keys/works%3Atype#overview [6]) which describes either the product or the type. Also, the power=* space is a world of its own and there are quite a few industrial facilities in the man_made=* space such as 37k man_made=wastewater_plant or 128k man_made=storage_tank (http://taginfo.openstreetmap.org/keys/man_made#values) [7]. So, if we exclude the power=* world and the man_made=* description of specific industrial objects, if we discount the marginal presence of factory=* (which may perhaps be discouraged considering the dominance of alternatives), that leaves us with either standalone industrial=* or the combination of man_made=works with a complementary tag such as product=* or works:type=* - which both have merits and popularity. So, what does [email protected] thinks about that ? Is the tagging of industrial production sites and their products ripe for standardization ? Which way seems like the right one to you ?
