Flateau (Building footprint data in Japan)

We prepared data for each city where original Plateau (National government open data project) CityGML data are available in 2024/05. The Plateau project keeps adding more cities every year. So, hopefully we can keep adding more cities in the future. You can download data as geoparquet or geopackage formats and use our data freely under CC-BY 4.0 license.

Japanese Building Footprint Data (a.k.a Flateau :wink:)

Original PLATEAU (National Government 3D project) building data are provided as the CityGML 3D format. We extracted LOD0 geometries (footprint 2D polygon) and their attributes and exported as GeoParquet and GeoPackage files. We used FME for this process and internally called Project Flateau. We kept attributes as much as possible, however, we omitted some of them based on our judgements. We addes several attributes such as heights and areas from the original 3D geometris. Japanese national and local government keep expanding data coverage, however, PLATEAU data don't cover the all cities in Japan (211 cites out of about 1720 cities). I hope the coverage will expand and cover the entire nation sometime.

There are lots of attributes in this dataset. We separated ancillary data from the main data, 2D polygon and centroid point data.

You can download and use our data freely under CC-BY 4.0 license. We used PLATEAU data so you also need to follow their term of use.

Polygon and Centroid data have gml_id columns which you can use to join attributes from other tables.

Directories are organized by data types.

2023 building data

Prepared data (整備したデータ)

We prepared data for each city where Plateau data are available on 2024/05. Plateau project keeps adding more cities every year. So, hopefully we can keep adding more cities in the future.

2023年度のPlateauの建物データの変換を行いました。毎年整備対象都市が増えているのでできれば毎年追加していきたいと考えています。

Prepaed data fromat(整備したデータのフォーマット)

We prepared our data in two data formats and host at Source Cooperative. If you click the following download page links, you will open the data download pages.

  • GeoParquet/Parquet (download page)
    • Footprint polygons and their centroid data as well as other ancillary data which don't have geometry information. You can join these data to GeoParquet data using gml_id column.
  • GeoPackage (download page)
    • All with or without geometry data are in this file.

File naming convention (ファイルの命名規則)

  • GeoParquet and Parquet files
    • citycode_cityname_year_filename.parquet
    • example: 01100_sapporo-shi_2020_building_centroid_lod0.parquet
  • GeoPackage files
    • citycode_cityname_year.gpkg
    • example: 01100_sapporo-shi_2020.gpkg

File names(今回整備したファイル名一覧)

We prepared the following files/layers for each city. Available data files/layers vary depend on its availability. We prepared polygon and centroid data are in GeoParquet format and other data are in Parquet. GeoPackage files include all data as one file.
