Usage

library(sits)

cube <- sits_from_hf(
    repo       = "felipemcarlos/sits_mod13q1_sinop",
    output_dir = tempdir()
)

plot(cube, band = "NDVI", date = "2013-09-14")

Contents

Images are named <satellite>_<sensor>_<tile>_<band>_<date>.jp2, the naming convention sits uses for local data cubes. The directory sits holds the files sits reads to open the dataset: sits/sits.yml describes the collection (bands, satellite, sensor, period), and sits/cache.rds holds the data cube, so sits_from_hf() does not open each image to describe it. Both are written by sits_to_hf().
