What am I seeing
The mountains around your chosen point, with names, heights and distances. On a phone you can turn on the compass to orient the drawing in the direction you are looking.

The exact coordinates are used in your browser for the calculation. Terrain data for the chosen area and a list of summits are downloaded to produce the panorama.
The panorama is ready, with 30 summits marked.
Punta Spartivento · 45.9913° N · 9.2655° E · 198 m
In the middle ·
The highest of the labelled summits is Monte Galleggione, 3107 m, 45 km away; the nearest of those marked is Sasso San Martino, 862 m, 3.7 km away.
The calculation considers only the terrain, not clouds or haze: the distant summits show only on clear days.
One degree at a time all round, from the eyes of a person standing; paler is farther. Heights are stretched two and a half times; the directions are the true ones. Houses, and trees within half a kilometre, are not in it.
Drag it sideways; with the keyboard, use the arrow keys.
The summits marked
From north, clockwise: the bearing in degrees, the height and the distance as the crow flies. Choose a summit and the panorama turns to put it in the middle.

How it is worked out
The panorama reconstructs the terrain and labels summits estimated to be visible from the chosen point. The actual view also depends on clouds, haze and nearby obstacles.
The method, step by step
First come the terrain heights round the point, out to twenty-two kilometres and, where the near ridges let the eye reach further, to two hundred. In Lombardy they are the Region's terrain model with its woods; outside the region, the open heights.
Then a line leaves the point at every degree, all round, and along each one the highest point is found within each band of distance: the near slope, the far shore, the ridges behind, the Alps. The drawing lays them one over the other, from the farthest and palest to the nearest and darkest.
The calculation compares summits with the terrain in front of them. For distant summits, the estimate is affected by the data resolution. It labels the highest estimated visible summit first, then the most prominent, keeping labels at least four and a half degrees apart.
If you turn on the compass and the device provides a direction, the panorama follows the phone's orientation. Otherwise you can drag it sideways.
