Terrain visibility analysis
Statue of Liberty from Brooklyn
A structure-height example across New York Harbor, illustrating the distinction between ground elevation and the top of a monument.
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.
Open and recalculate this analysisPoints and assumptions
- Observation point
- Brooklyn Heights, United States
- Point of interest
- Statue of Liberty, United States
- Geodesic distance
- 4.1 km
- Initial bearing
- 259.5° (west)
- Refraction
- Standard (k = 0.13)
What this example helps you study
Open the analysis to inspect the terrain profile, minimum sight line, visible part of the target and confidence level. Then change observer height, refraction or sampling interval to measure their influence.
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.
