%description
An end-to-end toolkit for land use and land cover classification using big
Earth observation data. Builds satellite image data cubes from cloud
collections. 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 and
to reduce training samples imbalance. Provides machine learning algorithms
including support vector machines, random forests, extreme gradient
boosting, multi-layer perceptrons, temporal convolution neural networks,
and temporal attention encoders. Performs efficient classification of big
Earth observation data cubes and includes functions for
post-classification smoothing based on Bayesian inference. Enables best
practices for estimating area and assessing accuracy of land change.
Minimum recommended requirements: 16 GB RAM and 4 CPU dual-core.
