普通建物 normal building building=yes
普通無壁舎 normal roof building=roof

List all factors that will be evaluated in the import.


  • Workflow
  1. Devided the shapefile as 83 neighbourhood area. (done)
  2. Convert them as .osm file. (done)
  3. Run JOSM validation on each .osm file.
  4. Load .osm file to JOSM, and download raw data for target area.
  5. Conflate with existing data.
  • Changeset size policy

None, the most biggest file size is 704kb (7484 objects).

  • Revert plans

This import will be done by dedicated account "Urayasu_bld_import".

So if some problems happen, I'll revert it's changeset one by one.


Existing data has priority.

Will be checked by JOSM validation.
