Reactions to this topic show different visions and point to various problems with a proper way of recording the source of our mapping. Suppose this:

A new building (in my hometown) appears on the map because it was imported under the BAG rules that were accepted in the Dutch community. One of the tags added with this import is: source=BAG.

Next, a grocery is starting buisiness in that building and is added by me (to the existing tags) and I can do this because of local knowledge. But at the same time I add the phone-number for that shop, using the yellow pages as source and from an advertisement for that grocery I can learn that they only sell natural grown groceries.
I have now 3 different sources at the same time.
Should I:

• record all that source-information in the changeset comment?

or

• add this information to the existing source=BAG tag, separated by “;”?

or

• create phone:source=yellow pages etc, etc, for all the other sources?

Very nice, interesting reading!
Reminds me of my series of diary entries: Improving the OSM map - why don’t we?
And especially the one regarding language use.

What is it that you want to share with us? Marc.

@Simon,

It doesn’t matter very much where (and how) the source information is stored if it is incomprehensible to others…

Btw, your opinion and the wiki differ.
Moreover, general use (see taginfo) shows that the source tag (and the source namespace) is in wide use.

Marc.

@Littlebtc: Thank you for clarifying!

No indeed, that’s not possible. But I always carry my tablet with me when I’m fixing those notes, reading the notes on the spot self - from my screen. Which give me also the oppurtunity to fix them right away. Of course for complex edits that is not the best solution, given the limitation of mobile editiors, but changing names, adding tags etc. is easy to do with GoMap

But there is definitely a use for your tool! Nicely done!

Nice idea with some helpfull extra’s, but you probably should also have a look at Pascal Neis’ site:

http://resultmaps.neis-one.org/osm-notes

Which has many options to retrieve notes on a per country basis (as a RSS feed!) and to select between notes that have a comment and notes that don’t.

I use this tool daily to check for notes in my country (which is small).

Marc.

Thanks!

I see that the relevant entry is removed now!

To me this is pure spam!

@leodobrasil See my nr. 1 example! Below the picture is the explanation with semicolons. You obviously missed it.

@Hendric Stattmann: I have never used Maproulette before, so I’ll give it a try, but have to find out how! Maybe it is something that might help. But as @SimonPoole noted, the problem is not the most important task we have to solve…

Thanks @Hedaja for the link to Jochen Topf’s blog! I didn’t know that. Seems that Jochen and I are concerned about the same.

@leodobrasil Making the permalink work with the User Pois is on my ToDo list!

Hello Stephan!

With openpoimap (previously: taglocator) you have also the option of showing fixme’s!

Being a browser/desktop application, it was not designed in the first place to be used on a mobile device, but it does work!

Marc.

With openpoimap it is even more striking! Openpoimap is a great tool to discover (and sometimes fix) this kind of data. I start developping it a few months ago and it has an increasing number of users. Especially useful to check if data you have entered on the map is correct.

Hi Alexandre,

Please reread the last two paragraphs of my post, because what you propose is exactly what has been done by someone, but then it was reverted by another person on the grounds that it was a mechanical edit.

Test?

@Warin61, @mcld,
When I’m travelling on my bicycle (sofar 100000+ km) I use my Garmin GPSmap62 to navigate. When I’m searching for something I need (hotel, restaurant, bicycle shop), the GPSmap shows me where those POIs are, but none of the other tags are visible. So, having no chain-tool is possible, but I cannot see on my Garmin map they don’t have one. Hence it should not be called a bicycle repair shop. Maybe I decide to take a detour to get there (having some problems with my chain) only to find out they can’t help me. In such a case I prefer no information over partial information.

Of course the precise definition of a Bicycle Repair Shop is still open…

(And I always carry a chaintool myself on my trips)

Escada, the point is that for every redundant tag (as is the case with the entrance key), programmers have to take into account every weird combination of tags in order to have the program work. But it is impossible to take all these combinations into account because one doesn’t know them all. In my next story I’ll show some of those.

The next link from taglocator shows the problem: http://mijndev.openstreetmap.nl/~marczoutendijk/openpoimap/taglocator.html?map=amenity&zoom=18&lat=60.16636&lon=24.9395&layers=B00FFFFFFFFFTFFFFFFFF

This church is shown with 3 markers because the entrance is marked in the deprecated way (building=entrance). The more inconsistency in the database the more problems show up when trying to get the data work for you.

Remember: Garbage In, Garbage out.

You missed my point Escada: a chain tool is very basic to a bicycle repair station. If they don’t have that tool, it is not a bicycle repair station!!
(A swimming pool without water, do you call that a swimming pool?)
