Dataset Card for Rock Glacier Detection
Dataset Summary
Rock Glacier Detection dataset with satelital images of rock glaciers in the Chilean Andes.
Supported Tasks and Leaderboards

Dataset Structure
Data Instances
A sample from the image-classification training set is provided below:
df = load_dataset("alkzar90/rock-glacier-dataset", name="image-classification")
df["train"][666]
> {'image': <PIL.PngImagePlugin.PngImageFile image mode=RGBA size=128x128 at 0x7FB2EC58C6D0>,
'labels': 0,
'path': 'train/cordillera/1512.png'
}
A sample from the image-segmentation training set is provided below:
df = load_dataset("alkzar90/rock-glacier-dataset", name="image-segmentation")
df["train"][666]
> {'image': <PIL.PngImagePlugin.PngImageFile image mode=RGBA size=128x128 at 0x7FB2EB7C1160>,
'masks': <PIL.PngImagePlugin.PngImageFile image mode=RGBA size=128x128 at 0x7FB2EC5A08E0>,
'path': 'train/cordillera/1512.png'}
Data Fields
The data instances have the following fields:
image: APIL.Image.Imageobject containing the image. Note that when accessing the image column:dataset[0]["image"]the image file is automatically decoded. Decoding of a large number of image files might take a significant amount of time. Thus it is important to first query the sample index before the"image"column, i.e.dataset[0]["image"]should always be preferred overdataset["image"][0].labels: anintclassification label.
Class Label Mappings:
{
"cordillera": 0
"glaciar": 1,
