For storage tanks: have a box: covered? (but set no default)

[jidanni]

For storage tanks, have a box

• [x] covered (assumed yes)

Where "no" is the exception,

I second that. In arid and forested areas, is important to tag if the water tanks are covered or not. I always have to add the covered=yes/no tag, but this would be helpful.

Well in several places of the world is the other way, covered is the exception and Not the rule, indeed mostly of South America and Africa are Uncovered, basically because the cost of construction raise exponencially.

Hmm, https://www.google.com/search?q=should+you+cover+a+water+tank? says covering it is important...

[jjiglesiasg]

I understand what you said, but minor and personal (household) small water tanks are usually NOT mapped but large constructed tanks with concrete walls and located in agricultural, natural parks, highlands and water deprived areas and Mostrly if not All are Uncovered.

Actually, it is irrelevant if it's the exception. We're merely asking for a selection box to add a tag saying if the storage tank is covered or not.

Them I do agree with you, currently such feature is not an option in the menu for Storage Tanks. Should be like Driveways under roofs for example...

I've only added this field (in 889821d) for water tanks (i.e. man_made=storage_tank + content=water) for now, because for many other tank types this tag doesn't seem to apply or is simply not used (ignoring of the apparently implied covered=yes value), e.g. for all tanks holding gasses, or substances like oil, chemicals, hot water, etc.

[AntMadeira]

That seems reasonable. Thanks!

@tyrasd

Hi there again. In the last update, the covered field was added to emergency=water_tank + landuse=reservoir (btw this tag has been deprecated), but not to building=yes + content=water + man_made=storage_tank, which is a very used preset in iD. Can you please also add it?

Thanks.

[AntMadeira]

Hi there. Just to bump this request. The preset for building=yes + content=water + man_made=storage_tank still doesn't have the covered=* field. The field would also be very useful for building=yes + content=water + man_made=storage_tank + emergency=water_tank.

Regards.

The covered field is present as an optional field on both the "Water Tank" and "Emergency Water Tank" presets:

I guess you mean that this field should be promoted to a regular field which is always shown to mappers for these presets?

I think I initially only implemented this as an optional field because of two reasons:

• a) the osm wiki doesn't really mention the usage of the covered tag on things like water tanks: The examples given are mostly things which have a roof structure above them, while a covered water tank could also be covered with a flexible foil or a moving lid. It would be good to see the use case for water tanks also be mentioned on the wiki.
• b) usage of the covered tag on water tanks (i.e. osm features with the tags man_made=storage_tank + content=water) is quite low: From out of 100,000 objects, only about 400 use the covered tag.

I can live with that hidden field, even if its not always shown to mappers as a regular field. Nevertheless, this is important for me because I live in an area prone to wild fires in the summer and there area many water reservoirs scattered in the mountains. I can not map them all, but those who map them and know only what they see in iD, should know that there's an option to clearly differentiate covered from open emergency water reservoirs, which is important to those who fight the fires.

I edited the wiki to clearly state that it includes "an area such as an underground parking lot, a covered reservoir/cistern or even such things as an aquarium", which is the text that was written originally in the approved proposal.

Regards.
