+## Data Fields
+```
+index: An integer representing the unique identifier for each example.
+image: A PIL image.
+split: A string indicating the data split, e.g., 'train', 'validation', or 'test'.
+labels: A list of dictionaries, each containing:
+  class: An integer representing the class identifier.
+  label: A string representing the class name.
+  x: A float representing the normalized x-coordinate of the center of the bounding box.
+  y: A float representing the normalized y-coordinate of the center of the bounding box.
+  width: A float representing the normalized width of the bounding box.
+  height: A float representing the normalized height of the bounding box.
+altitude: A float representing the altitude at which the image was taken (if available).
+aperture: A float representing the aperture setting of the camera (if available).
+area: A float representing the code of the geo-area in which the image was taken (if available).
+date: A string representing the date when the image was taken (if available).
+device: A string representing the device used to capture the image (if available).
+exposure: A float representing the exposure time of the camera (if available).
+focal: A float representing the focal length of the camera lens (if available).
+height: An integer representing the height of the image in pixels.
+width: An integer representing the width of the image in pixels.
