The Ground Sample Distance (GSD) the distance between the pixel centres, measured on the ground.
The GSD depends on the camera parameters such as focal length, sensor resolution and sensor size and the distance to the ground. With the help of our calculators, you can determine the GSD and also take into account the motion blur due to the ground speed.
The parameters of all our camera systems and the available lenses are already available and can be selected. To avoid motion blur, the value for distance ∆Xi (distance covered in the image/ on sensor during the exposure time) should ideally not exceed 1 pixel. The value for ∆X (distance covered on the ground during the exposure time) should not exceed the desired GSD.
We are constantly updating our GSD and FOV calculators with the latest available camera models and lenses. Please write to us at https://support.phaseone.com/ to get the latest version.
