3. Finalise today's agenda

4.  Database contact and re-map

Global picture:

  • Older contributor acceptances now 61,125. 425 declines.
  • Monthly history planet dump done and [1] stats updated, so now shows the effect of re-mapping.
  • Nodes that will likely not survive the license change are down from 24.1M to 23.57M (slowing) [2]
  • Problematic Ways down slightly (actual figure was wrong in the draft minutes and has been deleted) [2]
  • Problematic relations down slightly to 41.7K [2]



Lost mappers:

We are now down by roughly 40'000 highways compared to the start and from a contributor point of view around 20% of the contacted mappers have reacted and accepted.

Nearly all mappers on the list have received at least a further e-mail with the exception of

- those on the list for Portugal, Czech Republic, Austria and Sweden

- mappers in Poland and Kosovo

Further noteworthy items:

- there are 4 deleted accounts in the list, largest user_34262, created ~2,000 highways. The system admins have releases of the data to OSM for all four, so I would assume that we can mark all such data as clean.

- some support from the German community has now turned up

- we have at least one high value mapper "tere" (16,000 highways in Central America) that we know name and employer that I hope we will be able to reach, this is currently with Ivan Sanchez.

We discussed Haiti and if there was anything more specific we could do.  Mikel Maron, as a board member, is aware and championing,

5. Technical Rebuild

Historical planet dump can be done after the change-over from an SQL dump that willl be made … solved possible timing issues.

- Data lingering. Do we need to keep things in the db? Should stuff be expunged completely or kept in the db but hidden from distribution under ODbL

Old data is not thrown out, it is available in one form or another, e.g. CC-BY-SA planet dumps. We feel that for the current db, technical considerations should take precedence.

The only requirement that the LWG has is that any lingering data should not be accessible under normal publishing conditions … it is the publishing that is important.

6. OSM Poland

Discussion continuing.

7. OSM Czech Republic

Dermot will take this on.


- Attribution after the license change

Richard Fairhurst has made a first draft of  this (see: 3a. I would like to use OpenStreetMap maps. How should I credit you?) and also a post-license-change License FAQ: 

Mike - advertise on legal talk for comments when Richard F has done further drafting.

Next Meeting:

Tuesday Mar 6th 11:00 PST / 14:00 EST / 19:00 UTC / 19:00 GMT(UK) / 20:00 CET
