Landmark terrain cases 名建形巒案例
Public buildings, public data, printed limitations. Each case samples the 360° skyline from open elevation data once, freezes it into the page, runs the same kernel judgments as the API, and puts every data caveat next to the data it qualifies. No living persons are assessed; no verdict is narrated beyond what the kernel computed.
Forbidden City 故宮
The canonical "backed by a mountain, facing open water" template — Jingshan (the artificial hill raised in the Ming) is directly north, and the Golden Water bends in front. What do…
Beijing, China · 1406–1420 (rebuilt/expanded through 1912)
Taj Mahal 泰姬陵
A river to the north instead of the south — the "water in front" template inverted. A useful case for showing the kernel reports the terrain as measured, not as the template expect…
Agra, India · 1632–1653
Sydney Opera House 悉尼歌劇院
Three sides open water, southern hemisphere: the four-意象 labels (azure dragon / white tiger sectors) follow the compass, and the kernel just reports elevation symmetry. Also an hon…
Sydney, Australia · 1959–1973
Why these three
- The Forbidden City — the canonical mountain-back/water-front template, and a live demonstration of a real free-DEM limitation (the 45 m back hill is flattened in 30 m tiles).
- The Taj Mahal — the template inverted (river behind), on a genuinely flat floodplain: a "boring" skyline that is the honest result.
- The Sydney Opera House — a modern building where "sitting direction" is not a given, so the white-tiger judgment is honestly not run, and the page explains why.
