Corrections to sits_kohonen and to the documentation.
New deep learning models for time series: 1D convolutional neural networks (sits_FCN), combining 1D CNN and multi-layer perceptron networks (sits_TempCNN), 1D version of ResNet (sits_ResNet), and combination of long-short term memory (LSTM) and 1D CNN (sits_LSTM_FCN).
New version of area accuracy measures that include Olofsson metrics ()
From version 0.8 onwards, the package has been designed to work with data cubes. All references to "coverage" have been replaced by references to "cubes".
The classification of raster images using sits_classify now produces images with the information on the probability of each class for each pixel. This allows more flexibility in the options for labeling the resulting probability raster files.
The function sits_label_classification has been introduced to generate a labelled image from the class probability files, with optional smoothing. The choices are smoothing = none (default), smoothing = bayesian (for bayesian smoothing) and smoothing = majority (for majority smoothing).
To better define a cube, the metadata tibble associated to a cube requires four parameters to define the cube: (a) the web service that provides time series or cubes; (b) the URL of the web service; (c) the name of the satellite; (d) the name of the satellite sensor. If not provided, these parameters are inferred for the sits configuration file.
The functions that do data transformations, such as sits_tasseled_cap and sits_savi now require a sensor parameter ("MODIS" is the default)
Functions sits_bands and sits_labels now work for both tibbles with time series and data cubes.
sits_show_config() to see the default contents. Users can override these parameters or add their own by creating a config.yml file in their home directory.Examples and demos that include classification of raster files now use the inSitu R package, available using devtools::install_github(e-sensing/inSitu).
All examples have been tested and checked for correctness.
sits_coverage has been replaced by sits_cube.
sits_raster_classification has been removed. Please use sits_classify.
In sits_classify, the parameter out_prefix has been changed to output_dir, to allow better control of the directory on which to write.
sits_bayes_smooth has been removed. Please use sits_label_classification with smoothing = bayesian.
To define a cube based on local files, service = RASTER has been replaced by service = LOCALHOST.
For programmers only: The sits_cube.R file now includes many convenience functions to avoid using cumbersome indexes to files and vector: .sits_raster_params, .sits_cube_all_robjs, .sits_class_band_name, .sits_cube_bands, .sits_cube_service, .sits_cube_file, .sits_cube_files, .sits_cube_labels, .sits_cube_timeline, .sits_cube_robj, .sits_cube_all_robjs, .sits_cube_missing_values, .sits_cube_minimum_values, .sits_cube_maximum_values, .sits_cube_scale_factors, .sits_files_robj. Please look at the documentation provided in the sits_cube.R file.
For programmers only: The metadata that describes the data cube no longer stores the raster objects associated to the files associated with the cube.
