- •
A quick and inexpensive way to measure visual parameters of landscape is proposed.
- •
Apparent density is presented as a new visual parameter of landscape.
- •
Visual angles/magnitudes or densities are used to assess landscape changes.
- •
Panoramas can be unambiguously defined using just the coordinates of the viewpoint.
- •
The method can be used for calibrating viewshed and visual magnitude calculations.
