[OSM-ja] Yahoo data cleanup

[Satoshi IIDA]

Hello Arun,

I would like to confirm 2 points.

1.
If someone would like to "pass" for some municipality,
where is the best method to contact with?
(Github? or this Mailing list? or some others?)

Like Muko-Shi ＠ Kyoto, some mappers did enormous efforts to survey.
I guess most of roads could be adjusted to correct geometry & connections.

2. Planning Tondabayashi road import
Some mappers are planning Tondabayashi ＠ Osaka road imports.

It seems already checked and "passed" as valid.
Do you have any plan to those area?

AFAIK, no other road imports are planned in Japan region.

Regards,
