such as width, height, focal lenght ecc. to compute the GSD manually

The FOV of the camera is automatically set when you choose a drone as specified by the specifications of that drone on DJI’s web page.

Also have a look at this thread:

Web application to calculate horizontal and vertical fields of view (FOV)

I have created a web application that will compute the horizontal and vertical fields of view (FOV) for DJI drones given the diagonal FOV provided in the DJI specifications. This information may be of interest to those using drones to perform mapping services. In addition to the horizontal and vertical FOVs, the following items are also computed and provided (based on the desired height of the drone, desired overlaps, and time between photos): Equivalent 16x9 video FOVs Horizontal and vertical…
