[Talk-us] migrate surface=cement to surface=concrete on USA roads and paths

[Kerry Irons]

Concrete is cement, sand, and gravel.  Cement is the glue that holds concrete together.  Sidewalks are concrete.  Roads and bridges (and buildings) have some sort of rebar in the concrete but otherwise it is the same as a sidewalk or a swimming pool.

Using the KISS method, I have always associated cement with sidewalks and paths while concrete is for roads and bridges. If my understanding is correct, you cannot use concrete to make cement however, you need cement to make concrete.

Looks like a good change but I agree with Frederik, let's first see how people are putting this in. Looks like there are no presets that mention the word cement for surface. The only mention of the word cement in an ID tagging preset is for plasterer craft type. Given that the edits you mention use iD, I think this may just be a user not liking the value "concrete" that was in there.

Based on my research it seems safe to retag

surface=cement

to

surface=concrete

on roads and paths in USA.

 

In your research, have you covered the question how surface=cement is introduced - is it a particular editor/preset/task that causes lots of these, or is it something that users enter manually?

no, but I would look in case of new ones appearing especially if they would appear in

large volumes (I continue to inspect sample of edits made using

https://www.openstreetmap.org/user/Mateusz%20Konieczny%20-%20bot%20account/history#map=2/40.7/0.0

)

 

I just created 

https://wiki.openstreetmap.org/wiki/Mechanical_Edits/Mateusz_Konieczny_-_bot_account/migrate_surface%3Dcement_to_surface%3Dconcrete_on_USA_roads_and_paths/stats

if anyone wants to look at this data.

 

Numbers are too low for presets, I think.
