| ### Dataset Summary | |
|  | |
| Rock Glacier Detection dataset with satelital images of rock glaciers in the Chilean Andes. | |
| ### Supported Tasks and Leaderboards | |
| - `image-classification`: Based on a satelitel images (from sentinel2), the goal of this task is to predict a rock glacier in the geographic area, if there any. | |
| - `image-segmentation`: ... | |
| ### Languages | |
| Spanish | |
| ## 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`: A `PIL.Image.Image` object 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 over `dataset["image"][0]`. | |
| - `labels`: an `int` classification label. | |
| Class Label Mappings: | |
| ```json | |
| { | |
| "cordillera": 0 | |
| "glaciar": 1, | |
| } | |
| ``` | |
