Option
3D view (PLATEAU)
An option that shows the exterior of the buildings you manage in 3D, using PLATEAU data from Japan's Ministry of Land, Infrastructure, Transport and Tourism (MLIT)
This video, about one and a half minutes long, shows how buildings in the ledger are displayed in 3D using PLATEAU data from Japan's Ministry of Land, Infrastructure, Transport and Tourism (MLIT) (Japanese subtitles)
Footage is illustrative
Ichigen-cho is a service of DiO inc., not a service of Japan's Ministry of Land, Infrastructure, Transport and Tourism
Option
3D view (PLATEAU)
Because it uses PLATEAU data from Japan's Ministry of Land, Infrastructure, Transport and Tourism (MLIT), there is no need to build a 3D model from scratch
- Shows the buildings registered in the ledger in 3D, set in the surrounding cityscape
- Finds the building from the registered address and shows it after you confirm it on a map
- Marks the ledger's buildings with color
- The managing company shows the owner the building in 3D
- For interior floor plans, we recommend the Sumaho DE Zumen feature

Flow
How to apply
- First, search for the building by its address
- Next, confirm on a map that "This is the right building"
- Confirm that the owner has agreed, and then apply
- After you apply, the building in your ledger is shown in 3D
- A screen for checking all of this is available before you apply

PLATEAU is a 3D city model project promoted by Japan's Ministry of Land, Infrastructure, Transport and Tourism
Because it is based on 3D city model data, there are slight differences from the actual building
