If you use an aerial drone to survey land, you need to know about ground sample distance, or GSD for short. Calculating GSD is essential to determining the scale of your mapping project and ensuring reliable results. Without it, you run the risk of collecting inaccurate data or having a ma...
Ground sample distance (GSDOne of the most important parameters when formalising the specifications for a photogrammetric project is the ground sample distance (GSD). While there are a variety of methods for the computation of the mean GSD for an aerial image, the aim of this research paper ...

###Ground Sample Distance Calculator Calculates the Ground Sample Distance (GSD), which is the distance covered by one pixel as it is measured on the ground for a given pixel size, focal length, and altitude (AGL.) ###Altitude Calculates the altitute (AGL) necessary to acheive a specific...
Ground Sample Distance (GSD) is the distance between the centre of two adjacent pixels measured on the ground. It is a measure of accuracy in aerial mapping and remote sensing operations. Learn how to calculate GSD and find out more about why GSD is important for drone surveying on the blog...
Ground sample distance, for example, is a calculation used to explain how the real world scale established by GCPs translates to a map. The GSD describes the distance between the center point of two consecutive pixels on a digital image. Without an accurate GSD, it’s impossible for surveyors...
Image resolution: How much detail is desired? A smaller ground sample distance (GSD or pixel resolution) will have a higher resolution compared to a larger one. The flying height and focal length of a cameras sensor determine the pixel resolution. ...
Best practices suggest that the accuracy of control should be three times better than the ground sample distance (GSD) of the final product. However, due to the high resolution of commercial drone imagery, this guideline may be difficult to achieve, resulting in products with slightly lower accu...
Images were acquired as uncompressed RGB-color TIFF files with 0.97 mm·pixel−1 ground sample distance (GSD) sensor resolution. (GSD is a measure of the spatial resolution of a digital image; it is defined as the linear dimension of a Measurement Subjectivity TAP resulted in significant ...
