Terrain visibility analysis

Can you see the Brocken from Hanover?

Short answer: No, from this exact point at Kröpcke in central Hanover. Modelled terrain about 300 m southeast of the square blocks the line to the Brocken summit.

Can you see the Brocken from central Hanover? Sightelo analyses the 87.8 km line from Kröpcke square and finds blocking terrain.

This result applies only to the studied point at Kröpcke. Moving a few hundred metres or using a higher viewpoint may change the terrain horizon; Sightelo does not assign this verdict to all of Hanover.

Terrain profile and line of sight

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. The calculated obstacle is 0.2997 km from A. It rises 4.8 m above the sight line locally; the projected deficit at the summit is 1413.3 m. These are different quantities. Nearby terrain requires a minimum target altitude of 2554.3 m, above the summit's actual 1141.0 m. The minimum visibility line continues beyond the chart without changing its slope. 020406080020040060080010001200Blocking obstacle · 0.2997 kmBlocking obstacle · 0.2997 km A · ObserverB · SummitDistance (km)Apparent altitude (m)
  • Calculated terrain
  • Observer–summit sight line
  • Minimum visibility line
  • 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.

The calculated obstacle is 0.2997 km from A. It rises 4.8 m above the sight line locally; the projected deficit at the summit is 1413.3 m. These are different quantities.

Minimum line off scale — Nearby terrain requires a minimum target altitude of 2554.3 m, above the summit's actual 1141.0 m. The minimum visibility line continues beyond the chart without changing its slope.

What this example helps you study

The modelled line toward the Harz crosses slightly higher ground very close to Kröpcke, about 300 m from the observer. The Brocken therefore falls below the calculated terrain horizon from this exact point, even before considering buildings or haze. Another place in Hanover may give a different result.

Terrain about 300 m away defines the modelled horizon. At the Brocken, the summit is about 1,413 m below the minimum elevation needed to clear that horizon from this point.

Limits of interpretation

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

A positive value means the summit clears the modelled terrain horizon. A negative value means the summit lies below the minimum elevation required to clear that horizon. This value is not the local height of blocking terrain above the sight line.
