%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, and Digital Earth
Africa 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>, residual
networks by Fawaz et al (2019) <doi:10.1007/s10618-019-00619-1>, and
temporal attention encoders by Garnot and Landrieu (2020)
<doi:10.48550/arXiv.2007.00586>. Performs efficient classification of big
Earth observation data cubes and includes functions for
post-classification smoothing based on Bayesian inference, and methods for
uncertainty assessment. 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.
