The FieldStation GUI allows the user to control and monitor the imaging process. A focus check window shows a cropped portion of the live camera feed, while the larger window displays the saved image. In the right panel, various verification statuses are displayed. We use Laplacian variance to detect blurry and out‐of‐focus images and give the user a chance to take a sharp photo. The suffix “_b” is optionally added to all blurry photos for quick quality control. GPS information is also displayed here and can be refreshed independently of capturing an image. FieldStation can save all images and metadata to four USB storage devices simultaneously for data redundancy.
