Details of Import Data

licence

We will import the data opened under CC BY 2.1 Japan license. These data can refer the webpage of Tondabayashi city . Because the proponent of Tondabayashi/Road Building import includes the public officer of Tondabayashi City, there seems no need for additional permission.

Data File

Tondabayashi geospatial data delivered by ESRI Shapefile format.

• 　building (polygon)

The position accuracy of the data correspond to 1:1000. Data produced at March, 2015.

• 　road (line)

The position accuracy of the data correspond to 1:2500. Data produced at March, 2015.

Data Preparation

Tagging Plans

Tagging plans are as following rules.

Tondabayashi geospatial data (building)

feature(geometry type)	attribute	classification (by Japanese)	code	OSM tags
building (polygon)	SHUBETU	normal (普通建物)	1	building = yes
	SHUBETU	concrete (堅牢建物)	2	building = yes building:structure=concrete building:material = concrete
	SHUBETU	normal, no wall (普通無壁舎)	3	building = roof
	SHUBETU	concrete, no wall (堅牢無壁舎)	4	building = roof building:structure=concrete building:material = concrete

Tondabayashi geospatial data (road)

feature(geometry type)	attribute	classification (by Japanese)	code	OSM tag
road (line)	NAME	road name (道路名称)	‐	name
	flag of direction (方向フラグ)	oneway (一方通行)	1	oneway=yes
	rosen_no	road number(路線番号)	‐	ref

tagging rule from road(line) data "TYPE","Width" attribute to "highway" tag

Shapefile(TYPE)	Shapefile(Width)	OSM Tag	OSM Tag by Japanese
no motorway in Tondabayashi city	‐	highway=motorway/(highway=motorway_link)	自動車専用道路（接続路）
national road (一般国道)	‐	highway=trunk　（link）	国道（接続路）
main regional road（主要地方道）	‐	highway=primary/(highway=trunk_link)	主要地方道（接続路）
prefectural road (府道)	‐	highway=secondary/(highway=secondary_link)	一般都道府県道（接続路）
municipal road (市道)	over 5.5m	highway=tertiary/(highway=tertiary_link)	一般道（２車線以上）（接続路）
municipal road (市道)	1.5～5.5m	highway=unclassified	一般道（２車線未満）
municipal road (市道), Null※	under 1.5m	highway=path highway=footway(bicycle=yes/no) highway=service	小道(農林業用小道（里道等）) 小道（居住区域付近の路地） 敷地内道路（住居以外）
Null※	over 1.5m	highway=residential	居住区域内道路
Null※	over 1.5m	highway=service	敷地内道路（住居以外）
Null※	over 1.5m	highway=track	農道・林道
walk *遊歩道*	‐	highway=pedestrian	歩行者専用道
bicycle exclusive *自転車専用*	‐	highway=cycleway	自転車専用道
‐	‐	highway=road	道路（区分不明）

※"TYPE" Null roads contain "residential"."service" and "track". The identification of tag will be executed by checking Bing/GSImaps/ort satellite images.

Changeset Tags

These source tags are added to the imported data as a changeset comments.

• source = Tondabayashi Map Data
• source_ref = https://www.city.tondabayashi.osaka.jp/map/1050/download.html

Data Merge Workflow

Team Approach

The data will be imported by helicoysfh_tondabayashi_import(mainly import road), seicom_tondabayashi_import(mainly import building) and nissyyu_tondabayashi_import (supervision of nissyyu).These accounts(***_tondabayashi_import) were acquired exclusively for importing Tondabayashi data.

Workflow

• Workflow

1. Road (line) Shapefile except national road/prefectural road/main regional road will be divided to small town units because of data handling.
2. Shapefile will be load to JOSM by using OpenData plugin.
3. comparing/checking manually between the loaded Shapefile and the existing OSM data.
4. The data will be selected by the data accuracy and the particularity of the OSM tags.
5. Edited data uploaded by JOSM.
6. national road/prefectural road/main regional road uses existing OSM data to maintain existing relations and road(line) Shapefile will be used for fixing the shape of these lines.

• import Phase
  • Importing will be executed and repeated phase 1 and 2 by small town unit level as a principle.
  • Phase 1　import road(line) Shapefile
  • Phase 2　import building(polygon) Shapefile

• Revert plan

importing are executed by using accounts for Tondabayashi import(***_tondabayashi_import). If the problems occurred accidentally, corresponding changeset data reverted by helicoysfh_tondabayashi_import under the supervision of nissyyu.

Conflation

The data will be selected by the data accuracy by comparing with Bing data or GSImaps/std data and joined existing data which have detailed OSM tags . National road/prefectural road/main regional road uses existing OSM data to maintain existing relations and road(line) Shapefile will be used for fixing the shape of the line. JOSM validator will be used for conflation.

QA

For keeping quality of data, the manual import will be executed with the renewal of Tondabayashi geospatial data annually. The additional imports are also done and chacked with JOSM and JOSM validator.
