One of the examples in the package

A layered SVG coloured from a table with a few lines of plain JavaScript: every entity is a path whose id is its official code. The page shows a part of the country: the two levels share the same borders, so they fit without gaps. The package has every entity of every level.

Osaka Prefecture: its municipalities, coloured by area, among the neighbouring prefectures.

What is in the package

Levels and identifiers

LevelEntitiesIdentifier
country1JP
prefectures47JP-P-<official code>
municipalities1,747JP-M-<official code>
wards171JP-L-<official code>

Every entity has the same identifier in every file: it is the feature id in GeoJSON and TopoJSON, the id of the path in SVG and the id column of the tables. The history lists 2,017 suppressed municipalities with their successor.

  • full: the boundaries as published by the source.
  • 100m: simplified within 100 m and coherent: wards, municipalities and prefectures share exactly the same border vertices.
  • 1km: simplified within 1 km and coherent like 100m, every level: the whole country on a web map.
  • 10km: simplified within 10 km and coherent, country and prefectures only: small maps and maps of many countries.
  • light: country and prefectures only, each level simplified on its own to a small file.
  • GeoJSON: one FeatureCollection per level, WGS84. TopoJSON: all the levels in one topology, shared borders are shared arcs.
  • GeoPackage: data/geopackage/jp.gpkg (411.9 MB), one file for QGIS and ArcGIS with every level at every scale as a layer (municipalities_100m) with its spatial index, and every table of the package.
  • Shapefile: one per level and scale, WGS84, UTF-8; the columns longer than ten characters are shortened (region, province, abbrev).
  • SVG: one file per level and one with every level as a layer, in a Lambert conformal conic projection; they open as layers in Illustrator, Figma and Inkscape.
  • SQL: a script for PostGIS, one for MySQL 8 and one for SQL Server (14.8 MB each). It creates one table with every entity of every level, its 100m boundary in WGS84 and its indexes.
  • JSON: data/json/tree.json (146 KB), the levels nested and sorted by name, without boundaries: what the select boxes of a form need.

Tables

CSV, UTF-8. Names in EN, IT, ES, FR, DE, NL, PT, besides the official one.

code, name, province_code, replaced_by_code, replaced_by_name
tables/changes.csv 0 What changed from one edition of the package to the next, one row per entity added, removed, renamed, moved or with a new boundary: the same as CHANGELOG.md.
