[HOT] Japanese earthquake projects

Greetings John and all,


I will try to help connect you with the local team.  To ‘take us back’ and try to answer some of your questions – this response has from the start been coordinated by CrisisMappers-Japan. So maybe it is a language issue and they did not understand your message? However, what was maybe ‘missed’ was a quick ‘identification’ by the local team, that the immediate search and rescue operations would be done by ‘traditional first responders’ who would have their own maps and such, so this has always been more a ‘long-term’ recovery/just further helping the wonderful efforts of OSM-Japan in general, however I too would like to know if that has changed and/or any ‘use cases’ that have come up since then.


In general, these are good and valid questions/concerns, and HOT is always working to improve not only our own coordination, but how we better support these local groups.  Language barriers, time zones, and many other things contribute to communication challenges, so patience is always key around OSM.

I'm surprised to have no response to what is happening in Japan.  I think surprised is the polite way of putting it. 

I even tried to contact the project manager but no response.  It is now Tuesday morning in Japan.  I looked at a couple more.

I note that 1799 wants the sea mapping, or at least a third of the tiles would seem to be over the sea.  

1798 there is a high priority zone but much of it is not tiled.

1788 there is a high priority zone but some of it is not tiled.

1784 wow we've done a really good job of validating the sea on this one.

1786 again lots of sea to map.  We haven't managed to do the high priority zone.

These are in addition to the issues on 1800.

In total there are some dozen projects mostsy high priority relating to earthquakes in Japan that's asking for a lot of resources.  I think what we've ended up with is too few mappers spread out over too many projects to get anything useful done in a reasonable time frame.  Are they still high priority?


Yes mappers don't cost anything in money terms but surely we can expect a higher standard of project management than appears to be the case here especially with Ecuador needing to be mapped at the same time.

I've sent something to the project manager maybe we'll hear something after the weekend.

I would also note that it looks like we have some relatively new (8 total OSM change sets) mappers playing the role of validator and invalidating tasks for things beyond the requirement of the project (e.g. "incorrect paths set" when the project [#1844] only called for buildings).

I've been mapping and validating on Project 1800 but it doesn't make a lot of sense.

The most difficult part to map is the built up areas with lots of very close buildings which in some ways I'd expect a city in Japan to have its own maps of buildings. Those tiles take time and lots of it.  The buildings are so close together that you really need the building tool to map them rather than squaring them afterwards.

These tiles by the way still have a lot of buildings to be mapped even though the project says 82% complete I'd say we're only a third the way through the buildings.

Then we have lots of tiles over the ocean, nothing there, and many many tiles over forest, again not much to map.

Could someone expand a little more on who has asked for the mapping and what it will be used for?

Thanks John
