Hello guys!

In highways coding it is necessary to put the ref=[] tags and name=[], simultaneously?

In my view, it is only necessary te ref=[]. I doubt if the systems that use OSM find roads only with the tag ref=[] without the tag name=[*].

I understand that the two tags together generate unnecessary duplication of information.   English by: Google tanslate

Some streets have only a name, and some have only a number. It is not necessary to use both tags.

"Some streets have only a name, and some have only a number. It is not necessary to use both tags." If there is only on tag=yes, but if both tags are present then both should be used is not it ? So make it possible to search for both values ?

ref and name represent two different things, it isn't duplicated information. As Frederick said, some road have both a name and a ref, some have only one of the two, and some have neither. If a road has both a name and a ref, you should tag both, because you don't know which tag the data consumer will be looking for.

Thanks, but I was not specific. I wanted to refer when the tag name and the tag ref has the same description, as:

  • Tag name = BR-163
  • Tag ref = BR-163

In the above case, I understand that the tag nane is unnecessary. But if the name was the: South Atlantic highway, then yes, it would be necessary.

Seth, if the ref and name tag are the same, feel free to ask the mapper who added it why and how or the source ? It could be so, but Im curious because IMHO its a mistake if theres no sign, like you stated unnecessary.

So... the sources are known and the problem is not this, but the fact of the ref tag information is repeated in the name tag. I understand that this is unnecessary, because it generates too much information. My doubt is whether, by default, should be so.

For example, a highway with the ref tag=BR-450(fictitious), but no known name, as it should be added in OSM?

I understand that should be implemented as follows:
- Ref = BR-450 and without the tag name.

Now if her name was Highway South America:
- Ref = BR-450;
- Name = Highway South America
