RPAS Photogrammetry GSD calculator

Calculate the expected Ground Sampling Distance (GSD) by entering camera and planned flight parameters. All five input values are required for the calculations. Based on the Pix4D GSD calculator worksheet.

Example specifications of the DJI Zenmuse P1:

Sensor width: 35.9 mm
Photo width: 8192 pixels
Photo height: 5460 pixels
Focal length: 24 mm

Output:
GSD (cm/pixel):
