Ground Resolution Distance Formula, This article explains what the Ground Sampling Distance (GSD) is and how to calculate it. Use the GSD result to decide the best altitude and The simplest definition of resolution is the size of one camera pixel on the ground. This is dependent on the altitude of the system and focal length of the lens being In remote sensing, ground sample distance (GSD) in a digital photo of the ground from air or space is the distance between pixel centers measured on the ground. A smaller GSD means higher image Sentinel‑2 satellite provides freely accessible multispectral images used in various remote sensing (RS) applications, where spatial resolution is crucial. Calculate the Ground Sample Distance using the provided formula. Free. So if you want to avoid spatial autocorrelation, your ground sampling distance should be larger than it. The formula you mentioned, GRD=2 k GSD, relates the two parameters, where k is a constant that incorporates all the influences other than the sensor resolution and altitude. Explanation Calculation Example: Ground sampling distance (GSD) is a measure of the Calculation Example: The ground sampling distance (GSD) is a measure of the spatial resolution of a remote sensing image. GSD (Ground Sample Distance, or spatial resolution of an image) is a value that defines the size of the area of terrain corresponding to one pixel of the image obtained from the camera.
