GSD calculator

Enter your drone and camera details to see your inspection precision

Calculate the GSD (Ground Sampling Distance) here to evaluate the precision of your inspections! A lower GSD enables ultra-precise inspections, making it possible to detect defects as small as 1 milimeter and address issues before they escalate!

GSD means Ground Sample Distance (sometimes written “Ground Sampling Distance”). It’s the real-world size represented by a single pixel in an image captured by a drone

GSD is important because it’s the simplest way to ensure your imagery will be detailed enough to spot the defect sizes you care about (cracks, erosion, hotspots, cell defects, etc.).

It depends on the smallest defect you need to detect and how you’ll review images. As a rule: the smaller the defect, the smaller the GSD you should target. Use the calculator to find out!

To calculate your GSD, first pick your industry. Then select your drone and camera setup, and enter your flight distance to instantly see your GSD (cm/px). Adjust the inputs until you reach the level of detail you need.
