Import Type

This is a one-time import and will be done using manual efforts including using JOSM to validate the input.

Data Preparation

Data Reduction & Simplification

• Source tags are given to changeset rather than earch object.

Tagging Plans

There are 2 attributes in the shapefile, but doesn't make the sense in OSM, so it isn't used.

Simply taged to building=yes.

Shizuoka city does not have building classification data.
