Important notes

This geometry checker does not model luminous intensity, shielding, reflected light, curfew, or nuisance impacts.
Use it to identify receiver records that need separate obtrusive-light or neighbour-impact review.

Formulas

\(\displaystyle D = \sqrt{(x_r-x_s)^2 + (y_r-y_s)^2}\)
\(\displaystyle \alpha = \tan^{-1}((h_s-h_r)/D)\)

Estimate distance, vertical angle, azimuth, and review status for a nearby sensitive receiver.

Sensitive Receiver Geometry Checker is a planning aid. Keep the target source, product data, measurement method, and project assumptions with the result. Confirm compliance, installation, certification, and safety decisions with the responsible professional.
