This change also affects sen2r() products if reshaping features (reprojection or custom resolution) are required. This update was necessary due to changes performed in GDAL since version 3.2.0 (see OSGeo/gdal♯3294), which did not grant homogeneity between outputs produced with different GDAL versions. Note that, in case the user wants to update an existing sen2r archive produced with {sen2r} < 1.4.0, the old existing grid is maintained so that product grids are equal (in order to produce outputs with the new grid, users must create a new archive).s2_download() is no more able to use existing products equivalent to found ones.s2_download() no more uses existing SAFE products instead than downloading new equivalent ones (this in order to manage images split in two SAFE archives).{rgdal} changes in version 1.6-17.service to s2_list() and s2_download() for using "dhus" API service instead of default "apihub" (this could be useful in case of apihub downtimes).kill_errored to sen2cor() (see documentation).server to s2_list() to be used for future implementations.build_example_param_file() now generates more recent images, 2020-08-01 instead than 2019-07-23 (this because the previous ones required two SAFE which are now on LTA); the same was done for some tests.CLD, SNW, AOT, WVP (see documentation for description).

Now these files were replaced with an hidden TOML file .ignorelist.txt containing the list of base names of non-produced files and the dates of cloud covered images. This file is placed in the output folder, so to be linked with the produced archive. The usefulness of this edit is twofold:

Now the user can automatically order SAFE products which are not available for direct download, and use them when made available. Some internal functions can be exploited to manually manage orders.
Here above the related changes:
safe_is_valid() to check if an order was processed;s2_order() to order products from LTA.sen2r() and s2_download() have a new argument order_lta (default: TRUE) to order SAFE archives not available for direct download;s2_gui() has a new checkbox to set the previous argument.build_example_param_file() does no more compute TOA and RGB432T (this to avoid downloading 2 SAFE archives).
## sen2r CRAN release _________________________ sen2r was accepted on CRAN (2019-10-21, version 1.1.0). From now, it is possible to install the CRAN version with the following command:
The development version – which may contain updated features – can still be installed with the following command:
"list_prods" argument in sen2r() is NULL instead of 'BOA'.'no' value for argument "step_atmcorr" in sen2r() (use 'l2a' without selecting any L2A products instead)."smoothing" and "buffer" arguments in s2_mask() are now 0 (like in sen2r()) instead than 10/20 m.parallel = FALSE as default in sen2r() (parallelisation must be explicitly required).sen2r package directory is no more used to store files, but a subfolder .sen2r of the user Home directory is created and used. In this way, reinstalling sen2r will not require anymore to reinstall runtime dependencies / to reconfigure the package. The permission to write on this folder is asked to the user when the package is loaded for the first time.s2_list() and s2_download() now use internal methods instead of calling python function derived from s2download scripts by Hagolle (this substantially improve the speed of SAFE search), which were removed.sen2r is now supported also on MacOS.sp and rgdal from explicit dependencies.stringr and gdalUtils dependencies.stars dependency.str_pad2(), equivalent to str_pad() without the needing to load stringr.raster_metadata(), to get raster metadata, without rgdal dependency.check_scihub_login() to check if SciHub credentials are right.check_scihub_connection() to check for internet connectivity.build_example_param_file() (not exported) to build an example parameter file.testthat.check_gdal() was rewritten without using gdalUtils, in order to be simpler and faster."by groups" instead than "step by step": this ensures best computing speed and improves the management of disk usage, although it is not possible to see all the output messages in standard output (to see them, it is necessary to redirect them in a log file)."cloud_low_proba" is not yet available in the GUI (if is still a valid argument value for compatibility), and "cloud_and_shadow" now includes class “unclassified”. This in order to include “unclassified” only in “conservative” mask values, and to exclude it in non-conservative ones.httr: a change in Wget available version for Windows (1.20.3 instead than 1.19.4) caused the old link to break; moreover, downloading Wget using the new link was not possible with download.file() due to a redirect. So, httr dependency was introduced, and download of Wget, aria2 and sen2cor is now performed with GET function.dplyr: the internal function tiles_intersects() now perform dissolve operations over polygons of S2 tiles using dplyr commands (group_by() and summarise()).(see issues)
s2_calcindices(): now internal raster routines are used by default instead than gdal_calc.py, allowing reducing RAM usage and computation time.sen2r_getElements() was rewritten in order to:
sen2r();s2_calcindices() uses internal routines; the legacy mode can be used with the argument proc_mode = "gdal_calc" (default value is "raster").list_indices() now returns only checked indices by default (specify all = TRUE to return also non-checked ones).sen2r_getElements() is now a data.table instead than a list (use format = "list" to reproduce the old default).First stable release of package sen2r! See the announcement here.
path_out to path_rgb / path_indices is not yet necessary (if empty, path_out is used)tiles_intersects(): when an extent is loaded, now only required tiles are automatically used, instead than all the overlapping ones.v8 instead than to v8-3.14lwgeomsen2r() documentation. The 4 different modes allow to privilege stability, velocity or disk space. In this version, the legacy mode (“by_step”) is maintained as the default.s2_rgb() to produce RGB images, integrating it in sen2r() and in the GUI.s2_mask()s2_gui() was improved by adding a modaldialog which explains how to apply buffer and smoothing to cloud masks)check_gdal()sen2r()safe_isvalid() to check for valid SAFE archive names, and use it to filter existing SAFE folders (#104)s2_merge() or s2_calcindices()This is an improvement of version 0.3.2, with several fixes and improvements.

check_sen2r_deps(): a new GUI to help checking dependencies.
Add function s2_perc_masked() to compute the percentage of cloud-masked surface.
Major GUI improvements in the definition of the extent: now the main map is used only to show the extent and the tiles, while the definition of the extent (drawn, specified with a bounding box or taken from a loaded polygon) is done in separate maps (this allows to avoid many errors).
Add radiobutton for index datatype, to choose the datatype when an index is generated.
Add maximum cloud cover threshold.
Implement seasonal time period (#74).
Implement the download with aria2c.
Major commit: retrieve also existing filenames. Before this commit, if some products were partially retrieved (e.g. output BOA) and some depending on them are missing (e.g. an index) but SAFE were not required, the corresponding expected vectors were not retrieved (missing SAFE tile names nothing was generated). Now, existing names matching the parameters are attached to each "_exp" vector.
Manage parallelisation:
Improvement in integer / byte data types for generation of indices: Int16 is now the default data type; choosing an integer data type the output values are clipped on the valid format range, and the scaling factor can be chosen by the user; choosing Byte, interval -1 to 1 is coerced to 0-200 (with nodata=255).
Use standard nodata values to compute indices.
Return the list of created files after processing.
Accept custom mask combinations: now it is possible to define masks with a custom combination of SCL classes to be masked.
Allow argument “timewindow” in sen2r() to be a single integer value, which is interpreted as the period between today and n days ago.
Uniform temporary directories (#73). Now the principal functions have the parameters tmpdir and rmtmp to set the temporary directory and the choice to delete /not to delete temporary files. Only two exceptions: create_indices_db() uses a fixed temporary directory (since it is a function intended not to be run by end users); sen2cor() launched from sen2r() uses a default temporary directory if tmpdir is in a SAMBA mountpoint over Windows.
Update to sen2cor 2.5.5, and manage S2A L2A operational products (https://scihub.copernicus.eu/news/News00305).
Add a welcome message and a logo.
Change package name from SALTO to sen2r, and rename the main function consequently to sen2r().
Remove s2download as dependence (now it is integrated within the package).
Remove sprawl dependencies.
Avoid blurs and artifices in thumbnails. stack2rgb() now works with GDAL routines; gdalwarp is used instead than gdal_translate for reducing the size of input images (to avoid averaging NA values, which produced blurs on borders of BOA thumbnails); intermediate GTiff files are used to bypass the presence of artifices in SCL PNG thumbnails and to produce JPEG multiband TOA/BOA thumbnails.
Load python modules correctly. Now on Windows all the modules are imported using import_from_path() in init_python(), which is called anywhere modules are needed.
Fix unrecognised osgeo in Windows. When running gdal_calc in Windows with multiple Python installations, the wrong one (i.e. Anaconda) is used, and “no module names osgeo” error is returned.
Other minor fixes.
This is an improvement of version 0.3.1, with several fixes and secondary improvements:
Changes: - Allows output directories to be created by fidolasen_s2 (#54) - Convert NA arguments to NULL - Add check that the mask polygons are not empty - Add parameter extent_name (#58) - Add exception for Hub unavailable - Add support for multiple tiles and extent names - Allow to generate thumbnails also on maps with wrong naming convention … - Allow to generate thumbnails also on maps with wrong naming convention … - Add “tiles” argument to consider only specified tiles - Add the possibility to download products over Windows (#49) - Add extent_name in the GUI (#58) - Add automatic installation of Wget on Windows - Add support for TCI thumbnail
Some fixes: - Fix recognising gdalUtils after R restarts - Fix error applying sen2cor on oldname SAFE - Delete also L1C product when applying sen2cor on a copy of the SAFE - Fix to recognise all SAFE paths - Do not ask for overwriting dependences in non interactive mode - Fix the check on dstnodata length - Fix the number of polygons required to mask - Combine multiple features in mask / extent - Accept non-sf extents or sf with NAs within fields - Change TCI mask values (use 0 instead of NA in order not to create problems with 8-bit format) - Various fixes (see solved issues)
This version allows to perform all basic operations with Sentinel-2 data: finding and downloading the required tiles (on Linux), correcting them with sen2cor, processing them (merging adjacent tiles, clipping, reprojecting, rescaling, applying atmospheric mask) to create output multiband files (in a format managed by GDAL) and spectral indices.
The version follows the issued scheduled for milestone 0.3.0; future improvements with Sentinel-2 data are scheduled for release 0.4.0.
This is an intermediate version, which does not allow yet to perform a complete workflow, but it allows to manually find (s2_list()), download (s2_download()), correct (s2_sen2cor()), translate in a format managed by GDAL (s2_translate()) and merge by orbit number (s2_merge()) Sentinel-2 data.
An example of possible manual workflow is shown in the temporary script WIP/tutorial.R. For a complete automatic workflow on Sentinel-2 data, wait version 0.3.0.
