Ground sampling distance (Spatial Resolution)

Calculates the ground sampling distance (spatial resolution). This version of the function ignores angular distortion

GSD(altitude, angle_of_camera = 25, pixel = 4.5, focallen = 35)

Arguments

altitude	the height of the drone above the ground
angle_of_camera	the angle of the camera is set
pixel	pixel size in micrometers
focallen	Focal length

Value

Ground surface distance cm per pixel
