%description
An end-to-end toolkit for land use and land cover classification using big
Earth observation data, based on machine learning methods applied to
satellite image data cubes, as described in Simoes et al (2021)
<doi:10.3390/rs13132428>. Builds regular data cubes from collections in
AWS, Microsoft Planetary Computer, Brazil Data Cube, Copernicus Data Space
Environment (CDSE), Digital Earth Africa, Digital Earth Australia, NASA
HLS using the Spatio-temporal Asset Catalog (STAC) protocol
(<https://stacspec.org/>) and the 'gdalcubes' R package developed by Appel
and Pebesma (2019) <doi:10.3390/data4030092>. Supports visualization
methods for images and time series and smoothing filters for dealing with
noisy time series. Includes functions for quality assessment of training
samples using self-organized maps as presented by Santos et al (2021)
<doi:10.1016/j.isprsjprs.2021.04.014>. Provides machine learning methods
including support vector machines, random forests, extreme gradient
boosting, multi-layer perceptrons, temporal convolutional neural networks
proposed by Pelletier et al (2019) <doi:10.3390/rs11050523>, and temporal
attention encoders by Garnot and Landrieu (2020)
<doi:10.48550/arXiv.2007.00586>. Supports GPU processing of deep learning
models using torch <https://torch.mlverse.org/>. Performs efficient
classification of big Earth observation data cubes and includes functions
for post-classification smoothing based on Bayesian inference, and methods
for active learning and uncertainty assessment. Supports object-based time
series analysis using package supercells
<https://jakubnowosad.com/supercells/>. Enables best practices for
estimating area and assessing accuracy of land change as recommended by
Olofsson et al (2014) <doi:10.1016/j.rse.2014.02.015>. Minimum recommended
requirements: 16 GB RAM and 4 CPU dual-core.
