Pix4Dreact brings two options which can help the user limit the orthomosaic size.
The minimum ground sampling distance is a measure for pixel length, expressed in cm/px. The lower the GSD, the higher the spatial resolution. For example, a GSD of 5 cm means that one pixel in the image represents 5 cm on the ground (5*5 = 25 square centimeters).
The maximum total megapixels is a measure for spatial resolution. The more MP, the higher the spatial resolution of an image.
