This guide is designed to help you perform a rigorous accuracy assessment while minimising the effort to do so, by providing an overview of how to collect high-quality ground checkpoints. In this white paper you will find information on what a photogrammetry target is, what one looks like, what the dimensions are based on scale, where to place them, and how to locate ground checkpoints if a photogrammetry target is not available.
