[OSM-newbies] How to tag when building present

2014-12-19 Thread Gavin Scott 
In my area all the buildings have been drawn.

How do I tag the facilities located in those buildings?

Here are the options

   1. Create a point inside the polygon and tag that with the attributes of
   the fasciities/functions that operate within the building, say Hopsital, or
   Shop.
   2. Tag one of the nodes that form the building polygon with the services
   performed within. Perhaps one of the the entrance nodes.
   3. Tag the polygon line. (I think this is impossible as the line has
   already been tagged with the value building.

I should point out that all of these building polygons has been tagged with
key=building

Another question. If one of these buildings conducts more than one
function, say a bottleshop that also operates as a supermarket. these tags
must appear on different nodes? One node one value I believe is the
principal.

Thanks

Just remember, you can always change the tag if it wrong or could be better
described with a different feature.

I would recommend nodes tagged with individual features. For example, a
nearby grocery store also has a coffee shop, run separately from the
grocery, and a bank branch inside.  One option would be to tag the building
with the grocery store with two separate nodes, one for the coffee shop and
one for the bank. Additional tags could be added for ATMs, restrooms, etc.
Another option is to leave the building as building=yes with separate tags
for all the attributes.

My preference is based on the purpose of the building. If it a multiuse
building, leave the building as just a polygon tagged building=yes. If the
building was built for a specific amenity, such as grocery store or
hospital, then tag it building=yes with other appropriate tags.


 Another question. If one of these buildings conducts more than one
 function, say a bottleshop that also operates as a supermarket. these tags
 must appear on different nodes? One node one value I believe is the

You can use semicolon separated values, for example
shop=supermarket;alcohol. I tend to pick the one or the other, depending on
what you think is it major feature. But either way is probably correct.

Good luck,
Clifford
