The dataset provides training and valiation data for classifying images by time of day and season (time of year). The images are taken from the Skyfinder dataset, containing webcam images along with timestamps and geolocation. The annotations have been automatically derived from the metadata, which is sufficiently precise for season. For time of day, the annotation have been manually checked and corrected. The dataset contains 2,790 training files and 311 validation files per class for season, and 986 training files and 110 validation files per class for time of day.
