 This paper reviews existing methods for detecting and extracting boundaries from unmanned aerial vehicle, UAV, images. It then proposes a workflow for automating this process, which includes pre-processing, image segmentation, line extraction, contour generation, and post-processing. Examples of each method are provided, along with a discussion of advantages and disadvantages of each approach. Finally, the paper concludes with a summary of the proposed workflow and a discussion of its potential applications in cadastral mapping.
