Terrain visibility analysis

Can you see Mount Fuji from Tokyo?

This page documents the topographic route between the studied point in Tokyo and Mount Fuji's volcanic summit, without confusing geometric possibility with guaranteed observation.

Short answer: Yes. From the studied point in Tokyo, the 3,776 m summit clears the modelled terrain horizon across a 90.7 km sight line.

This page explains a reproducible Sightelo case. The result is recalculated on demand with the available elevation data; it is not a guaranteed real-world observation.

Terrain profile and line of sightCalculated terrain along the full route from observation point A to summit B. The sight line and minimum visibility line use the same curvature and refraction model as the calculation. At the summit, the target clears the modelled horizon by 502.7 m. No blocking terrain is calculated. The relief forming the horizon is 89.116 km from A. 02040608001000200030004000Horizon-forming relief · 89.1156 kmHorizon-forming relief · 89.1156 km A · ObserverB · SummitDistance (km)Apparent altitude (m)

  • 0 m reference (modelled curvature)
Terrain already includes modelled curvature and refraction (k = 0.13). The grey curve is the 0 m reference: subtract it from the terrain curve to read real elevation. Sight lines remain straight; no second curvature correction is applied. Vertical and horizontal scales differ.

At the summit, the target clears the modelled horizon by 502.7 m. No blocking terrain is calculated. The relief forming the horizon is 89.116 km from A.

The calculation models terrain, Earth curvature and standard atmospheric refraction. It does not model buildings, trees, clouds, haze or local atmospheric variations.

What does the Mount Fuji from Tokyo analysis test?

The profile reveals whether foothills beyond the plain rise above the line to the summit. Open the reproducible result in Sightelo to inspect the clearance and confidence calculated from the available elevation data.

How far is Tokyo from Mount Fuji?

The geodesic distance between the coordinates in this example is 90.7 km. The target uses the summit elevation supplied in the project: 3,776 m.

What limits a real observation from Tokyo?

Buildings, trees, clouds and haze are not part of the terrain model. The observer's exact position and height can also alter the nearby horizon in an urban environment.

How does Sightelo handle terrain towards Mount Fuji?

Sightelo samples the geodesic line, applies Earth curvature and standard refraction, then compares profile elevations with the straight line joining the summit.
