A few comments
The technical side looks reasonable (not overnoded, etc) I'd probably drop the source_ref tag What's the note:ja tag say, and why not just note? But, the big issue I see is the accuracy is bad. A few random examples - natural=wood over fields: lat=34.06263&lon=134.05145 - 250m - 500m misalignment between a golf course and the hole in the data: lat=34.03908&lon=134.18371 - This is a few trees by the side of a road in the middle of a city, not a wood: lat=34.04618&lon=134.58209 - The shape of the unwooded area doesn't resemble the data: lat=33.80402&lon=134.37063 From: Satoshi IIDA [mailto:[email protected]] Sent: Tuesday, July 30, 2013 7:26 AM To: [email protected] Subject: [Imports] Japanese KSJ2 data re-import (to fill up some erased) Hi, list.
