| Scenario location |
Only a preset scenario's coordinates or coordinates AI estimates from a free-text scenario's text. It cannot be set by clicking the map or by searching an address. |
| Data coverage |
The land-value locations and the zoning are Tokyo Metropolis data. At a location not inside any zoning polygon, no reference volume is computed. |
| Free-text length |
Text beyond 500 characters is not used. HTML tags are removed. |
| Free text that is rejected |
Text that is empty once tags are removed, and text that matches a registered pattern of invalid input. |
| Values AI estimates |
The instructions given to AI ask for a location between longitude 139.5 and 140.0 and latitude 35.5 and 35.85, an impact radius of 0.5 to 5.0 km and a land-value change cap of 0.0 to 0.3. The server does not check these ranges. |
| When AI returns no location |
Longitude 139.7671 and latitude 35.6812 are used; the map does not move and the reference volume is not updated. |
| Impact radius |
1.5 to 3.0 km for preset scenarios. For free-text scenarios, AI's estimate, or 2.0 km when none is returned. |
| Locations computed |
Locations within 2.5 times the impact radius of the scenario's location. |
| Land-value change cap |
0.15 to 0.25 for preset scenarios. For free-text scenarios, AI's estimate, or 0.15 when none is returned. |
| Locations not shown |
Locations whose change rate has an absolute value below 0.1%. |
| Results shown |
Only the result of the last scenario run can be shown at a time. |
| Calculation inputs |
Only numbers of at least 1 for 「敷地面積」, at least 0.1 for 「前面道路幅」 and at least 0 for 「隣地境界距離」 are used; anything else is treated as the default. |
| Site shape |
Treated as a square. |
| North-side oblique line |
Computed with the same value as the distance to boundary. |
| Absolute height |
Computed as 10 m; a 12 m designation and height control districts are not reflected. |
| Shadow regulation |
Not evaluated. |
| PDF report |
Only preset scenario results can be exported. The table lists every location in the result. |
| Interface language |
There is no control to switch it. |
