Drone Photography Settings Calculator

This calculator translates drone flight parameters into the ground-level numbers that matter for aerial mapping and photography: how much detail each pixel captures, how fast your shutter needs to be, and how many photos a survey will take. Ground Sample Distance (GSD) — the real-world size represented by one pixel — is derived from sensor width, flight altitude, focal length, and image width in pixels; it's the single number that determines whether your imagery is detailed enough to resolve the features you're mapping. From GSD the calculator works out each photo's real ground coverage (width, height, and area in hectares), then computes the minimum shutter speed needed to keep motion blur to one pixel or less, based on your ground speed relative to GSD — flying faster or lower demands a faster shutter to avoid smearing detail.

For mapping missions, it also calculates the photo interval (how often to trigger the shutter for your desired forward overlap) and flight line spacing (how far apart parallel passes need to be for the chosen side overlap), then rolls both into an estimate of photos needed per hectare for planning battery life and flight time. A key assumption is that overlap requirements apply symmetrically in both the forward and side directions using the same percentage; real mapping software often wants higher forward overlap (80%+) than side overlap for reliable photogrammetry stitching, so if your mission plan calls for asymmetric overlap, run this calculator twice — once with your forward-overlap value and once with your side-overlap value — rather than relying on one shared percentage for both directions.
