Hi all,

a geometry object. That is, we cannot simultaneously use amenity =
school and amenity = social_facility; social_facility = shelter for a
school with shelter functionality.

Some Taiwanese mappers proposed to add 'emergency' as prefix for
distinguishing shelter, e.g.,
emergency : amenity =  amenity
emergency : social_facility = shelter

I'm just wondering if it is a good manner for this case. Because the
tag 'emergency' is used for emergency facilities but not including
shelters. Thus, adding emergency prefix to amenity is suitable? Any
suggestions for such situation?


How about shelter=emergency?
I don't really see why social_facility would be applicable. I don't see 
why an emergency shelter would be connected to social services.

[Tagging] Specifying maxweight, when different weight limits are signed

[Jack Burke]

What's the right way to specify maxweight when the weight limit sign has
different values for different vehicles?  Just use the highest value shown?

For example, see this bridge:

Interesting case, the bridge can seemingly resist 25 short tons, yet for
smaller vehicules it takes less.

Do you know if this is a legal limit or if being smaller makes the weight
less spread out which can structurally damage the bridge?

If the first then I'd map the highest value, if the latter then the
smallest one.

Split values are somewhat frequent in the US.  Oklahoma and Oregon
definitely has different weight limits posted for bridges for straight
vans, single trailers, doubles (or some road train combinations like
triples, turnpike doubles, Rocky Mountain doubles...).

As the bridge appears to be quite short, it certainly makes a difference if a shorter vehicle loads the bridge with its full weight, while for a longer vehicle only a subset of its axles is on the bridge, while the remaining ones are supported by the solid 
ground.

I dont think the legal/physical nature of the restriction shouuld influence 
your tagging (unless you want to use the :physical tag suffix and distinguish 
the two).

When in doubt, err on the side of caution and tag the most restrictive value. 
Use the smallest limit for the maxweight tag and add tags like maxweight:hgv 
for the vehicle-specific limits. See the access tag on the wiki for examples.

Re: [Tagging] [OSM-talk] If a school is a shelter when a disaster happens...

[Dongpo Deng]

Hi Maarteen and Maning,

Thank you guys for comments.

I agree with Marteen's opinion. The social_facility is difficult to be
applied for emergency. social_facility = shelter seems mostly to be used
for homeless people or refugees [1]. Thus, the wiki page of social_facility
= shelter [2] is really confused.

Maning's suggestion is great! I will recommend Taiwanese mappers to
use evacuation_center=yes
for this case. It's also good for regional tag consistency.

[Tagging] If a school is a shelter when a disaster happens...

[Dongpo Deng]

Hi all,

There is a problem for tagging shelters. In Taiwan, some of schools are
selected to be shelters for villages or small regions when a disaster
happens. However, it is conflict to annotate two amenities on a geometry
object. That is, we cannot simultaneously use amenity = school and amenity
= social_facility; social_facility = shelter for a school with shelter
functionality.

Some Taiwanese mappers proposed to add 'emergency' as prefix for
distinguishing shelter, e.g.,
emergency : amenity =  amenity
emergency : social_facility = shelter

http://www.openstreetmap.org/relation/4790949

I'm just wondering if it is a good manner for this case. Because the tag
'emergency' is used for emergency facilities but not including shelters.
Thus, adding emergency prefix to amenity is suitable? Any suggestions for
such situation?

Cheers,
Dongpo
