![]() ![]() These parameters are generally preset by the camera manufacturer. ![]() Like all digital photography, drone image quality mostly depends on four variables: While a low altitude flight can capture plant- or even leaf-level details, enabling a whole new variety of use-cases, at higher altitudes this information is lost as each plant is represented by only a handlful of pixels What is Ground Sample Distance (GSD) and Why Does it Matter? Even low resolution satellite imagery (100+ times lower than from a drone) captures high-level details like field boundaries or in-field validation so there is no real benefit in flying at lower altitudes as even a 120 m drone flight will generate sufficient level of detailīut in precision agriculture or plant research, evaluating leaf shape, plant health or emergence patterns requires ultra-high-resolution imagery to isolate, magnify and measure minute details from the air.ĭrone image quality is measured as ground sample distance. You don’t need to see discrete plants or leaves, so a bird’s eye view will do, which is why a high-altitude image can suffice. ![]() If you can distinguish the borders and aisles, you can outline the field edges. So, what are you looking for?įor example, mapping field boundaries doesn’t require significant ground detail. Your mission’s purpose determines the image resolution required for various metrics. Let’s zoom in □ Agricultural Imagery Requires Detail
