Use this skyview estimator tool to calculate the visible sky area from a given point on Earth.
Skyview Estimator
This calculator estimates the sky view factor for an observation area based on various parameters. The sky view factor is an important indicator in fields such as urban climatology and architecture, showing the fraction of sky visible in a given location.
How to Use
To use the calculator, fill in the following fields:
- Length of the observation area
- Width of the observation area
- Average building height
- Average tree height
- Building density
- Tree density
- Observation height
Press the “Calculate” button to see the estimated sky view factor.
How it Works
The sky view factor is calculated based on the provided dimensions and densities of buildings and trees in the observation area. The more obstructed your view is due to these elements, the lower the sky view factor will be. The formula considers the height of buildings, trees, their densities, and the observer’s height to determine the visible sky fraction.
Limitations
This calculator provides an estimate based on average values and a simplified model. Actual sky view factors may vary due to non-uniform distribution of obstructing elements, varying building/tree shapes, and other environmental factors.
