eurosat_dataset: EuroSAT datasets

Description

A collection of Sentinel-2 satellite images for land-use classification. The standard version contains 27,000 RGB thumbnails (64x64) across 10 classes. Variants include the full 13 spectral bands and a small 100-image subset useful for demos.

Downloads and prepares the EuroSAT dataset with 13 spectral bands.

A subset of 100 images with 13 spectral bands useful for workshops and demos.

Usage

eurosat_dataset(
  root = tempdir(),
  split = "train",
  download = FALSE,
  transform = NULL,
  target_transform = NULL
)
eurosat_all_bands_dataset(
  root = tempdir(),
  split = "train",
  download = FALSE,
  transform = NULL,
  target_transform = NULL
)
eurosat100_dataset(
  root = tempdir(),
  split = "train",
  download = FALSE,
  transform = NULL,
  target_transform = NULL
)

Value

A torch::dataset object. Each item is a list with:

x: a 64x64 image tensor with 3 (RGB) or 13 (all bands) channels
y: the class label

Arguments

root: (Optional) Character. The root directory where the dataset will be stored. if empty, will use the default rappdirs::user_cache_dir("torch").
split: Character. Must be one of train, val, or test.
download: Logical. If TRUE, downloads the dataset to root/. If the dataset is already present, download is skipped.
transform: Optional. A function that takes an image and returns a transformed version (e.g., normalization, cropping).
target_transform: Optional. A function that transforms the label.

Details

eurosat_dataset() provides a total of 27,000 RGB labeled images.

eurosat_all_bands_dataset() provides a total of 27,000 labeled images with 13 spectral channel bands.

eurosat100_dataset() provides a subset of 100 labeled images with 13 spectral channel bands.

Examples

Run this code

if (FALSE) {
# Initialize the dataset
ds <- eurosat100_dataset(split = "train", download = TRUE)

# Access the first item
head <- ds[1]
print(head$x) # Image
print(head$y) # Label
}
