- •
Viewshed models based on more-detailed input data correspond better to reality.
- •
Only the number of false positives depended on input data precision.
- •
The predominant errors in models based on vector datasets were false positives.
- •
The model based on LiDAR data predominantly had false negatives.
- •
These trends were identical for various definitions of models' matching of reality.
