FOV Calculator

Field-of-View Calculator

Determine optimal settings by entering exposure time or aircraft speed

Navigate to each of three tabs to select your lens and enter your Altitude (AGL in m), Aircraft Speed (m/s), Overlap (%),  Exposure Time (ms), Flight Time (min) and Field Width (m).

Spatial Pixel = Ground Sampling Distance (GSD) also called Instantaneous Field-of-View (IFOV) that presume square pixels

Line Spacing = Distance between Flight Lines

Overlap = Side overlap percentage of adjacent Flight Lines
