- "Explicitly display data as business usage permission. without these expression, every data are categorized as public use and non-business treatment"

"National-Land Numerical Information based on JPGIS" is geo data provided by National Land Information Division, a section of National and Regional Policy Bureau(NRPB), Ministry of Land, Infrastructure, Transport and Tourism (MLIT), Japan

Licenses

Their terms of use is written in Japanese; a summary in English is as follows.

• 2-3. If you reproduce the National-Land Information or create derivative works, you must do a citation of the source (e.g., "「国土数値情報（○○データ）　国土交通省」", a literal translation, National-Land Numerical Information (XX Data), MLIT Japan).

• 3-1. You may use the National-Land Information free of charge.
• 3-5. Disclaimer. MLIT Japan makes no warranty on your use of the National-Land Information.

OSMFJ confirmed using of KSJ2 to OSM（2012/July）

(Answer from MLIT) 　No problem to import KSJ2 data into OSM. The source information is written to each Object as Tag(data attribution), and details are written on OSM wiki.(2012/12/02)

So, tags on each Nodes (means parts of way) method was deplicated. (need additional descriptions)

Accuracy/Quality

Almost "National-Land Numerical Information based on JPGIS" is based on "Digital Map 25000" by Geographical Survey Institute (GSI) Japan. Files are in XML format and datum is Japanese Geodetic Datum 2000 (JGD2000) which is based on ITRF94 and GRS80.

Type of data

Currently, following data are available for OSM use.

Please do not improt 国土数値情報　鉄道時系列データ due to license compatibility. It claims to only non-commertial use.

Sample of Tags

Tags below is a sample of the common tags to all of KSJ2 data. And this is a case of railway data 2007, so "type of data" (note, note:ja) and "url" (source_ref) should be adapted for each type of data.

For all ways or relations of KSJ2 data. (not all nodes. (2012))

    <tag k='source' v='KSJ2/NO3' />
    <tag k='source_ref' v='https://wiki.openstreetmap.org/wiki/Import/Catalogue/Japan_KSJ2_Import' />

See each pages for details.

How to import data

Xml files, xmlschemas, codelists and specifications can be downloaded from the site, so someone who is familiar with xml could convert the data to osm file.

KsjTool(v1.5), a java program for conversion from KSJ2 xml file to shape format files, is also available.

• User:Tatata made a perl script to convert the railway data from shape files to osm file. (ja)User:Tatataが鉄道データのshapeファイルをosmファイルへ変換するperlスクリプトを作成しました。 (notice: obsolete. please discuss on talk-ja ML first.)

Post Import Cleanup

Since I accidentially discovered several intersecting waterways in Japan I had a deeper look into the data. I looked for intersections of ways tagged with
waterway=canal
waterway=drain
waterway=ditch
waterway=stream
waterway=river
with the tool waycheck20.pl. On the script I disabled not matching for layers since all the imported waterways I checked had generally a layer= tag from -1 to -3 on them regardless the reality (compared with Bing). The waterways I extracted from japan.osm.pbf at geofabrik using osmfilter. The result with 2670 intersections you can find here.
A cleanup by the importers would be nice.
It also would be interesting to check the other parts of the import but I leave that to other people. :)

An updated check I will only deliver on request since the script is quite slow. As you can see on bottom of the result page it took more then 80 hours to run.
