This won't help for imports, but I've seen places where people have put in
ways along now-absent features with only a note= tag saying that the
features are now gone.  That at least catches people who are tracing from
outdated aerial imagery.

You can't rule that out, though. For example, the runways of RCAF Port
Albert are still in CanVec, but were dug up in 2006. Every time I'm near
there in OSM, I slide over and check to see that no-one's put them back.
They've reappeared once, and may do so again.

   It's very unlikely that there will be another import unless by chance 
there someone has created data that is of greater quality than we would 
typically see in OSM.

   There is some active work on reusing our changes.   So deletions and 
moves can be detected.  If you later create an area polygon for the 
element, copy all the tags from the node to the polygon, then remove the 
node.

Thanks. Now I'm wondering about a related issue: if I delete this node  
(which was part of a GNIS import) and a couple of years from now someone  
imports GNIS data again to pick up its updates, will we then see the old  
data in the map again? Are these mass imports a one-time-only event? If  
not, is there a mechanism to propagate our changes back to the data source?

If the node isn't significant, then I just delete it.  But something
historical I mark it as such.  For example the original Red Robbin
restaurant recently closed, so the building is marked accordingly.  Since
its on great real estate, it probably won't remain vacant long.

This node represents an amenity that ceased to exist at least 15 years

property.

Do I simply delete the old node? Or should it be tagged as historical and

Hi James,

Thanks a bunch ;-)



The idea was not to translate the page above into other languages.
The linked pages shell contain the spefic part of the project.
So they will be different, because the project partners will produce own
content.

The page linked above contains information written better than MOST
native English speakers would produce. Links to the various native

various languages. Are there more pages linked that should contain
English contents?

Manfred A. Reiter — 2012-04-29T06:38:25

Hi all,

5 countries (PT, RO, SL, TR and D) are working togehter in an european
 "Comenius project" called "BoostOSM"

We produce a wiki about the project
- the first (common) part *should be* in englisch
- the second (individual) part will be in the resp. languges of our partner.

We produced the first part.
As I wrote it, it is in "DEnglish" :-( ;-)

http://wiki.openstreetmap.org/wiki/Life_Long_Learning_Mapping_Project_-_EU-Comenius:_BoostOSM_-_DE3_LLP-Com-SV_(PAD)

Question:
Is here on the list sombody how could help us to transfer the wiki into
a wiki which contains "Oxford - English" ;-)

Thanks in advance

Re: How to draw land-use areas

This is already sometimes done for rivers, with "waterway=river" for

The line vs area debate is a perennial one and will not be solved any

In favour of lines:
- much easier routing
- much easier to re-use for many purposes: most of the time, the
information that people want about roads is essentially linear.
- easier to edit
- less information required to create and maintain
- better rendering at low zoom levels
- more flexible rendering (how would you render an area as a dashed line?)

In favour of areas:
- more precise
- allow calculations of other interesting kinds of information
- better representation of the "real world".
- less subjectivity
- better rendering at high zoom levels

This trade-off also comes up with rivers (riverbanks vs a line
representing the centre)...maybe other things too.

Me, I think the only real solution is a neat way to map both a line
and an area, simultaneously. Draw an area, and al

Re: Avoiding many changesets

Werner Poppele — 2012-04-18T11:23:04

JOSM keeps track of the last 15 changesets in its setupfile, normally in 
C:\Documents and Settings\<USERNAME>\Application Data\JOSM on Windows or 
$HOME/.josm on UNIX-based operating systems.
The filename is preferences.xml.

Or login at http://www.openstreetmap.org/user/<USER> and go to the edits 
you made. There is the full history of all of your changesets you ever 
created.

What do you mean by "keep track of"? What do you want to do with them?

Me, I probably have thousands of changesets - I don't really pay
attention to them. The data is what matters to me, now the
changeset...

Methods for this vary. My suggestion: try several methods, and see
what works best for you. Discuss with other people in your area, and
do what they do.

There are pros and cons either way.
