Can you see the mountains from home?

Everything you can see from there

The colour covers the ground you would see from the chosen point: the slopes that face you, out to the last ridge. What lies behind a crest stays uncoloured. Click anywhere on the map to see the panorama from there.

Mountains of 2,000 metres on the horizon, from the towns and communes where 56% of Romanians live

From the centre of 1,538 of Romania’s 3,181 communes, towns and cities, at least one peak over 2,000 metres would be in view in clear air, 30 metres above the ground. They are home to 10.6 million people, 56% of the population counted in the 2021 census.

The result moves little when the assumptions change. From 10 m instead of 30, the share is 53%. With a refraction coefficient of 0.07 or 0.17 instead of 0.13, two test scenarios rather than the limits of the real atmosphere, the share would be between 54.9% and 56.2%. With the terrain drawn finely even far away, it would be 56.0%.

The map has two halves. The plains of Oltenia and the Banat face the Southern Carpathians, the highest in the country, with nothing in the way: from Drăghiceni and Valea Mare, in Olt County, 47 peaks over 2,000 metres would be in view from each. In Moldavia, no commune centre in the counties of Iași, Neamț, Bacău, Vaslui, Vrancea and Galați sees a 2,000-metre peak: the nearby mountains are lower, and the high ones stay below the horizon. Ceahlău, at 1,907 m, falls short of the threshold, but it can be seen from the upper parts of Iași.

From the Carpathians you can see the Balkans and the Tatras

The higher you stand, the farther the horizon. From the Carpathian ridges the line of sight crosses the plains and reaches the mountains of Bulgaria and Slovakia, more than 300 kilometres away. Between two peaks that far apart the Earth’s surface bulges: halfway between the Retezat and the Balkan Mountains, by 2,215 m. The air bends light towards the ground and makes it look like 1,927 m, and the line of sight passes only 456 m above the Romanian Plain.

The calculation, set beside photographs

Where people have photographed or filmed very distant mountains, the calculation from the same spot shows nearly all the same peaks above the horizon; where it does not, the gap is a few tens of metres. The saying that you can see the Danube from Omu sits right at the limit of the calculation; the sea from Ceahlău does not show in the model.

Why you don’t see them every day

The calculation says how far the line of sight reaches, not whether the air lets light through. Dust and water droplets scatter light, and a distant mountain grows paler until it cannot be told from the sky behind it. Contrast falls exponentially with distance; meteorologists call the distance at which a dark object is just visible against the sky the visibility.

In the SYNOP code in which weather stations send their observations, the top visibility step is ‘more than 70 km’. From Bucharest the Bucegi have been seen on days of very dry, clean air, usually after rain or wind, in winter but also in summer. The four images below show the same view from the place chosen above under four kinds of air. Why it is the air, not the Earth’s curvature, that usually hides them: The horizon that lies.

How it was computed

The terrain

Terrain Tiles (Mapzen/Tilezen, on Amazon Web Services), a terrain model assembled from several sources, among them SRTM (NASA) and EU-DEM, sampled at about 110 m. Within 60 km of you the calculation uses cells of about 310 × 220 m; farther out, to 450 km, cells of about 925 × 650 m, each at the height of its highest point. Distant ridges between you and a peak therefore look a few tens of metres taller than they are: the calculation tends to hide peaks that are visible rather than show hidden ones. With fine terrain at every distance, the headline share would be 56.0%. The same terrain also shows when the sun clears your local horizon.

Curvature and refraction

For every direction, at every eighth of a degree, the calculation follows a ray out to 450 km and keeps the points that rise above everything nearer. It subtracts the Earth’s curvature and adds refraction: the air bends light towards the ground, and the calculation uses a coefficient of k = 0.13, the conventional value in geodesy rather than an atmospheric average. The real coefficient changes from day to day with the way air temperature changes with height; near the ground on sunny days it can be much larger, or even negative.

Where you stand

The centre of the seat of each commune, town and city, from Wikidata coordinates checked against GeoNames (89 points moved onto the seat), at the chosen height above the ground. The terrain model includes part of the height of buildings and forests, but not the block in front of you; that is why the national results are computed from 30 m and from 10 m, above the rooftops.

The peaks

Names and heights come from OpenStreetMap: 30,204 named peaks in Romania and the region, from the Tatras to the Balkans. Where OpenStreetMap gives no height or a plainly wrong one (459 of the peaks used), it comes from the terrain model; heights can differ by a few metres from other maps (Coștila is 2,498 m in OpenStreetMap, 2,490 m on Romanian maps). The panoramas show 5,286: those that rise at least 60 m above the saddle linking them to a higher peak, plus every peak over 1,800 m. A peak is in view if, at its height, it rises above the highest point between it and you. ‘Clears by 30 m’ means it could be 30 m lower and still be seen; under 30 m the result is marginal.

The country

All 3,181 administrative units, with population from the 2021 census. A ‘mountain’ here is a peak over 1,000 m that rises at least 100 m above its saddle. A commune’s or town’s whole population is counted at the centre of its seat: the percentages say how many people live in places with a view, not how many see the mountains from their own window.

What the calculation does not know

The buildings, trees and poles around you; fog, cloud and haze; the day you look. It shows what the eye would see on perfectly clear air, from the chosen height.
