List of railway lines

A list of railway lines from 'extra/json.zip' in Seo-4d696b75/station_database. The original data is here.

lines
lines

A tibble with 13 variables:

code: A value that uniquely distinguishes lines in the dataset. Unlike line IDs, it does not guarantee consistency between different versions of the dataset.
id: A string that uniquely distinguishes lines in the dataset. Unlike line codes, it ensures consistency between different versions of datasets (the IDs of the same lines be always the same IDs even if in different datasets).
name: Name of lines. A suffix may be added to prevent duplications.
name_kana: Hiragana representation of line names.
name_formal: The original names of lines.
station_size: How many stations does the line have?
station_list: A list of tibbles with 2 variables; code (station codes that the line is passing through) and name (their names).
company_code: Company (company codes) that ownes the line.
color: Image color of the line.
symbol: The symbol string of the line.
closed: Whether the line was closed or not?
closed_date: Date when the line was closed.
extra: Whether or not the line is implemented in the 'Ekimemo!' game app?

Polylines from 'extra/json.zip' in Seo-4d696b75/station_database. The original data is here.

polylines
polylines

A simple feature collection with 9 fields:

code: A value that uniquely distinguishes lines in the dataset. Unlike line IDs, it does not guarantee consistency between different versions of the dataset.
id: A string that uniquely distinguishes lines in the dataset. Unlike line codes, it ensures consistency between different versions of datasets (the IDs of the same lines be always the same IDs even if in different datasets).
start: Location where the polyline starts.
end: Location where the polyline ends.
name: Name of lines. A suffix may be added to prevent duplications.
north: North edge of the polyline (latitude).
south: South edge of the polyline (latitude).
east: East edge of the polyline (longitude).
west: West edge of the polyline (longitude).

A list of railway stations from 'extra/json.zip' in Seo-4d696b75/station_database. The original data is here.

stations
stations

A simple feature collection with 17 fields:

code: A value that uniquely distinguishes stations in the dataset. Unlike station IDs, it does not guarantee consistency between different versions of the dataset.
id: A string that uniquely distinguishes stations in the dataset. Unlike station codes, it ensures consistency between different versions of datasets (the IDs of the same stations be always the same IDs even if in different datasets).
name: Name of stations. A suffix may be added to prevent duplications.
original_name: Station name as indicated by each company.
name_kana: Hiragana representation of station names.
closed: Whether the station was closed or not?
lat: Station coordinates (latitude).
lng: Station coordinates (longitude).
prefecture: JIS code of the prefecture where the station is located.
postal_code: Zip code of the station's location.
address: Address of the station's location.
open_date: Date when the station was opened.
closed_date: Date when the station was closed.
extra: Whether or not the station is implemented in the 'Ekimemo!' game app?
attr: Station attribute in the 'Ekimemo!' game app.
lines: List of line codes passing through the station.
delaunay: List of the neighboring points (station codes) obtained by Delaunay partitioning.
