image_id - unique image id comprised of state abbreviation and UNIX timestamp

image_path - Image filename with a single parent directory

plant_date - plant date for entire batch. Does not account for replantings.

growth_stage - estimated growth stage based on planting date

width and height - image height and width in pixels. May be downscaled as a result of autosfm; however, image in the “images”directory are full sized images. See fullres_width and fullres_height
