Version 1.5.0 2021-06-27

Major changes

Minor changes

  • Restore check for existing equivalent SAFE products.
  • Edit ENVI tags for BOA-TOA (band names, wavelengths).
  • Automatic tests on sen2r() main functions were restored on Actions thanks to the implementation of Google Cloud download.

Changes in default values

  • s2_list(): argument availability has default value "ignore" unless server = c("scihub", "gcloud"), in which case default is "check".

Bug fixes

  • Fix #407.
  • Avoid messages “Spherical geometry (s2) switched on/off”.
  • Minor fixes.

Version 1.4.4 2021-05-10

New functions

  • is_scihub_configured(): accessory function which allows easily checking if SciHub credentials ca be read. It is used to selectively run tests and examples basing on that.

Minor changes

Bug fixes

  • Speed-up tests and avoid runtime GDAL being searched on CRAN (CRAN error with donttest).
  • Avoid sending queries to SciHub if credentials were not configured (CRAN errors with donttest).

Version 1.4.3 2021-05-04

Minor changes

  • Use API URLs instead of as required after changes at SciHub side (
  • Manage multiple SciHub credentials when ordering SAFE archives from LTA (experimental).


  • Replace http:// with https:// in documentation _URLs.


  • Replace Travis with GitHub Actions (and fix tests accordingly).

Bug fixes

  • Avoid topology errors on S2 footprints (to fix errors using sf 1.0).
  • Manage situations like in #397 (too many nodes for ESA API query).

Version 1.4.2 2021-03-04

Bug fixes

  • Fix CRAN error (invalid example).

Version 1.4.1 2021-03-02

Minor changes

  • Prevent Copernicus mismatches between API Hub and dhus (#381)..
  • Rescale resolutions lower than required in s2_translate() (#368).
  • Avoid using progress bars in non-interactive sessions.
  • Manage error 429 for dhus (resend APIs more times in case of too many requests).

Bug fixes

  • Partially fix #368 (determine the output projection before processing).
  • Fix #371.
  • Fix #383.
  • Fix after changes in units 0.7-0 (#390).

Version 1.4.0 2021-01-07

Major changes

  • gdal_warp() was partially rewritten: now reshaped rasters conserve square pixels also after warping operations. 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).
  • Manage images split in two SAFE products, to avoid producing black areas in these [uncommon] cases (see #353 for an explanation). As effects:
    1. now pixels outside footprints (including nodata outside orbits coverage) are always set to nodata;
    2. now s2_download() is no more able to use existing products equivalent to found ones.

Minor changes

  • Add templates for GitHub issues.
  • Do not return error in tests in case of SciHub server down (#354).

Changes in default values

  • Pixels outside footprints (because of previous point, or - more frequently - because outside orbits coverage) are always set to NA even if no cloud masking is performed.
  • 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).


  • Update vignette data (granting using online data) (#360).

Version 1.3.9 2020-10-14

Bug fixes

  • Fix check errors due to rgdal changes in version 1.6-17.

Version 1.3.8 2020-08-26

Minor changes

Changes in default values

  • 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.

Bug fixes

Version 1.3.7 2020-07-06

Major changes

  • Some additional products are now supported: CLD, SNW, AOT, WVP (see documentation for description). The GUI and internal functions were modified to support their selection and generation.

Minor changes

  • Add indices Red / Green / Blue Chromatic Coordinate (Rcc, Gcc, Bcc) and Excess Green (ExG) (#330).
  • All methods based on runtime GDAL are now discouraged and never called by default (before this version, they were used in case GDAL was found on paths.json).
  • Output GeoTIFF files are now tiled.


Bug fixes

Version 1.3.6 2020-06-04

Bug fixes

  • Fix GDAL usage over Windows (a new version was specifically released for this bug because it caused sen2r stopping for many Windows users).

Version 1.3.5 2020-06-01

Major changes

  • GDAL is no longer a mandatory external dependency, being used only to smooth/bufferise cloud masks (and optionally to compute spectral indices, RGB images and thumbnails).
  • “Graphical” packages needed to run the GUI (leaflet, leafpm, mapedit, shiny, shinyFiles, shinydashboard, shinyjs, shinyWidgets) are now suggested dependencies. In the case they are missing and the user tries to run the GUI, an error is returned with the command for installing them.

Minor changes

  • Edit the GUI in order to disable selectors when dependencies required to run them are not available.
  • Automatic tests were reorganised and improved after GDAL changes.


  • Document sen2r installation over Ubuntu Focal.
  • Update documentation according to GDAL changes.

Bug fixes

  • Fix Travis-lwgeom incompatibilities (#319)
  • Fix #310 and #311

Version 1.3.4 2020-04-22

New functions

  • gdalUtil(): function used to perform GDAL operations, calling C-based GDAL utilities using sf::gdal_utils(), and Python-based ones through system calls (a standalone GDAL environment is request to do it, as it was in previous versions).


  • Improve documentation of vignette “Output file structure”, including the description of output products.

New dependency

  • rgdal is now an explicit dependency (this because it is used by raster but it is not a mandatory dependency).

Minor changes

  • GDAL C-based utilities are called using internal GDAL routines in package sf (see gdalUtil()). This allows reducing the use of external runtime dependencies.
  • GDAL messages are suppressed if the suggested dependency sys is installed (#257).
  • The new section of the vignette “Output file documentation” regarding products is linked in the GUI.

Bug fixes

Version 1.3.3 2020-03-30

Major changes

  • Move the list of ignored / cloud-covered images in the output path (#271): before this release, two files (*_ignorelist.txt and *_cloudlist.txt) were created in the directory of the parameter file (if existing) and used, during subsequent sen2r() executions, in order not to try reprocessing images cloud covered or failed for some reason. 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:
    1. this information is strictly linked with the produced output files, and can be generated even in the case a parameter JSON file is not used;
    2. using cloud-covered dates instead of file names, additional products (e.g. spectral indices added at a later time) related to a date which is known to be cloud-covered are automatically skipped.

New dependency

  • RcppTOML (used to manage TOML ignore list TOML file).


  • Improve the installation page.

Bug fixes

  • Support for sf >= 0.9 (#260)
  • Patch for stars issue, made to resolve the temporary incompatibility with sf >= 0.9 (see issue #295)
  • Fix #292
  • Small improvements

Version 1.3.2 2020-02-27

New features

  • Add argument req_res to safe_isvalid() and rm_invalid_safe(): now the presence of the JP2 images required by the processing chain is checked by default. L2A products without all the three resolutions will not be used.
  • Add output field "res" to the default safe_getMetadata() output, with the list of the available resolutions (“all” is returned in case of L1C products).

New function arguments

  • Add argument timeout to sen2cor() to limit the maximum Sen2cor execution time (after that time, Sen2Cor is stopped). This is useful to avoid blocking processing chains due to internal Sen2Cor errors.


  • Add new suggested dependency sys (it is used to call Sen2Cor using sys::exec_wait() instead than system(), allowing exporting Sen2Cor output to log files).
  • Add new suggested dependency rgdal (since it is implicitly called by internal functions), as requested by CRAN policy.
  • Move units and tools to suggested dependencies.
  • Prepare to move shiny* and leaflet* dependencies to suggested (this will be done in a future release).

Minor changes

  • Allow choosing if ordering SAFE products from dhus or apihub (experimental).
  • Replace all GET() calls with RETRY(), so to avoid errors in case of temporary unavailability of services.
  • Allow Sen2Cor running with oldname SAFE (although the usage of these products is generally deprecated).
  • Bug fixes (#272, #276).

Version 1.3.1 2020-02-07

Major changes

  • Documentation was improved with three new vignettes about GUI usage, command line usage and output structure.

Bug fixes

  • Restore checking environmental variable in init_python() (this urgent bug fixing was the reason of the urgent release of the current version).
  • Fix building offline footprint.
  • Fix the Dockerfile.

Changes in default argument values

  • Accept both sen2r(..., rm_safe = "yes") and "all".
  • In the GUI, the maximum allowed cloud cover was set to 100% accordingly to the sen2r() defaults.

Minor changes

  • Add check on max_mask - mask_type coherence (if max_mask < 100 and mask_type is not specified, a warning is returned).
  • Suppress some useless warnings.
  • Switch examples on 2019 dates (previously examples were based on 2017 images, which were partially moved on LTA).
  • Do not print progress bars in logs.

Version 1.3.0 2020-02-04

Major changes

  • Support for GDAL 3 / PROJ 6 was added:
    • Edit internal function to deal with CRS instead than PROJ.4 strings
    • Allow st_crs2() accepting also WKT strings / EPSG codes in the form "EPSG:xxxx"
    • Edit GUI to accept WKT / to warn if a PROJ.4 is passed
  • After running sen2r() a short report is returned to output summarising the status of the required processing (see new internal function sen2r_process_report()). This should facilitate applying sen2r in a cycle until all “expected dates” are processed.
  • Management of Sen2Cor GIPP parameters: now the user can process L1C SAFE images applying a topographic correction (as done to produce L2A images on ESA Hub) or specifying other parameters managed by L2A_GIPP.xml file. To allow doing that, new arguments were added to sen2cor() and sen2r() (see below) and a new option was added in the GUI.

New functions

Deprecated functions

  • Internal function init_python() was deprecated (Python is no longer managed by reticulate).

Changes in default argument values

Minor changes

  • All components of the order (available, ordered and notordered) are now saved in JSON files. This allows using them to re-do an order, specifying if re-ordering already ordered datasets or only order the ones identified as “notordered” (based on new argument “reorder”).
  • Output messages are formatted so not to exceed output line length.
  • Add support for BigTIFF format.
  • Dependencies reticulate and magrittr were removed.
  • Checks on the validity of SAFE products were improved.
  • Add NDBI / NDVIre indices (#241).
  • Add footprint among metadata retrieved using safe_getMetadata() (from existing offline SAFE archives) and s2_list() (from SciHub online metadata).
  • Filter offline SAFE archives by footprint instead than by S2 tile ID, so skipping using images which do not contain any data for a specific Area Of Interest.
  • Add method to convert class safelist to sf (using footprint).
  • Rewrite st_crs2() using class methods (see the function help for newly accepted inputs).
  • safe_getMetadata() now directly read XML SAFE files instead than calling GDAL through reticulate (this avoids errors in particular OS conditions).
  • Do not use PROJ4 string with PROJ > 3 (
  • Retrieve the GDAL installation path using gdal-config instead than whereis gdalinfo.
  • Add a test for reprojection without EPSG.
  • Return a warning if SciHub is down.
  • Improve documentation about the problem occurring using newly created credentials.


Version 1.2.1 2019-11-12

Major changes

  • New safelist class for lists of SAFE Sentinel-2 archives (see safelist-class);
  • sen2r() execution now causes saving the used parameters in a json file located in ~/.sen2r/proc_par (this can be used to take trace of the executed processing chains);
  • safe_getMetadata() function was rewritten: now files are scanned only if the user requires metadata which must be retrieved from file content, otherwise only file names are analysed. Inputs can be also safelist objects. The support for oldname SAFE products is deprecated.

New functions / methods

  • link_sen2cor() can be used to link an existing Sen2Cor installation to sen2r;
  • as() methods can be used to convert safelist from/to character, data.frame and data.table (as well as as.character()',` functions).

Changes in default values

  • safe_getMetadata(): new arguments format, simplify and allow_oldnames (see the function reference for details);
  • s2_list(): argument output_type was deprecated (use to obtain a data.table instead than the new default safelist object);
  • safe_shortname(): arguments tiles, force_tiles, set.seed and multiple_names were deprecated, since they are not used with SAFE compact names (old names are no more supported);

Minor changes

  • Sys.setenv() effects now do not affect the R environment after exiting from sen2r() execution;
  • safe_shortname() does no more support oldname SAFE products;
  • the Docker version of the package was modified to support last package changes;
  • the delay between SciHub registration of new credentials and the possibility to use them on API hub is now documented in the GUI;
  • return a warning in case some LTA orders cannot be processed because user quota exceeded.

Version 1.2.0 Unreleased

Starting from this version sen2r supports ordering products from Long Term Archive (LTA) (see news at 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:

New functions

  • safe_is_valid() to check if an order was processed;
  • s2_order() to order products from LTA.

New arguments

  • 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.

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:


Version 1.1.0 2019-10-21

Changes in default values

  • The default value for "list_prods" argument in sen2r() is NULL instead of 'BOA'.
  • Remove 'no' value for argument "step_atmcorr" in sen2r() (use 'l2a' without selecting any L2A products instead).
  • Default values for "smoothing" and "buffer" arguments in s2_mask() are now 0 (like in sen2r()) instead than 10/20 m.
  • Set parallel = FALSE as default in sen2r() (parallelisation must be explicitly required).
  • Since old name products were repackaged by ESA, these products are no longer supported.
  • In the case the users manually defines the path to be used as temporary directory and this directory already exists, a casual subdirectory of the user-defined folder is used (this to prevent to accidentally delete existing files).

Major changes

  • 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.

New/removed dependencies

  • Remove sp and rgdal from explicit dependencies.
  • Remove stringr and gdalUtils dependencies.
  • Add stars dependency.

New functions

Other changes

  • Packages stability was improved by adding test functions, working with testthat.
  • S2 tiles are not provided as kmz within the package, but a rds file is downloaded after installing the package (in this way, package installation is lighter, and S2 tiles are read faster).
  • Function check_gdal() was rewritten without using gdalUtils, in order to be simpler and faster.
  • Some new indices were added:
  • The minimum convex hull of the extent is used instead of the bbox to search SAFE images.
  • Several “soft” error/warning messages were introduced.
  • ENVI headers now includes some information about band names (TOA/BOA) and SCL classes.
  • Coupling SAFE: in offline mode, if some L2A products exists but not the corresponding L1C, and TOA-derived products are required, only the “coupled” SAFE archives are used.
  • Small base example files were added to the package for testing purposes.
  • Sen2Cor version which the user wants to install can be chosen in the GUI.
  • Documentation was updated and improved, in particular adding function examples.
  • Unused old code was removed.
  • Several bugs were fixed.

Version 1.0.2 Unreleased

Changes in default argument values

  • the default running order is now "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 masks: "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.

Edits in the GUI

  • add commands to manage parallelisation and running order (with documentation)
  • add button to export output messages in a log file
  • add MathML code for some custom spectral indices

New dependencies

  • 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()).

Minor improvements

  • check the list of parameters whenever it is loaded

Various fixes

(see issues)

Version 1.0.1 Unreleased

Changes from version 1.0.0

Major changes

  • A new algorithm was implemented in s2_calcindices(): now internal raster routines are used by default instead than, allowing reducing RAM usage and computation time.
  • Better RAM usage and reduction of execution time: sen2r_getElements() was rewritten in order to: 1) avoid a RAM leak present in the function, which was causing a high RAM use in the first part of the execution of sen2r(); 2) considerably speed up the execution (now the metadata of 100 files is retrieved in 4 milliseconds instead than 80).

Changes in function defaults

  • 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).
  • the default output format of sen2r_getElements() is now a data.table instead than a list (use format = "list" to reproduce the old default).

Various fixes.

Version 1.0.0 Unreleased

First stable release of package sen2r! See the announcement here.

Changes from version 0.3.4

GUI changes:

  • Highlight selected tiles in the map (now red) in respect to unselected ones (grey)
  • Hide TCI product (replaced by RGB images)
  • Implement orbit selector and change the style of tile selector
  • Make boxes collapsible
  • Use shinyfiles to load extent (for coherence with other file selectors in the GUI)
  • Copying path_out to path_rgb / path_indices is not yet necessary (if empty, path_out is used)
  • Add loading spinner
  • Other style improvements

New functions

  • tiles_intersects(): when an extent is loaded, now only required tiles are automatically used, instead than all the overlapping ones.

Update dependencies

Bug fixing:

  • Fix bug in SciHub login
  • Fix maps (tiles were hidden)
  • Fix:missing dependency lwgeom
  • Various fixes (#140, #141, #142, etc.)

Version 0.3.4 Unreleased

Major improvements

  • Implement 4 different processing orders in order to fasterize processing. See “processing_order” in sen2r() 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.
  • Add new function s2_rgb() to produce RGB images, integrating it in sen2r() and in the GUI.
  • Add a dockerised version of sen2r:


  • Change base cloud masks:
    • class “Saturated and defective” is masked within all masks;
    • class “Dark area pixels” is masked in masks in which “Cloud shadows” was masked;
    • mask “cloud_shadow_cirrus” was renamed to “clear_sky”;
    • a new “land” mask was added.
  • Add “nomask” level to s2_mask()
  • Names of ratio indices now uses “:” instead of “/” (#123)
  • Index TCI_idx now is TCIdx
  • Use a default extent name (leaving it empty is now not allowed, in order not to confuse with naming convention of merged files)

Other improvements

  • Improve SAFE filtering: removing duplicates; filtering by position (only the ones overlapping the extent); do not perform a double check of existing products in offline mode.
  • Improve GUI: improve cloud mask helper (documentation within s2_gui() was improved by adding a modaldialog which explains how to apply buffer and smoothing to cloud masks)
  • Allow sen2r working with GDAL 2.1.2
  • Allow GDAL path to be specified in check_gdal()
  • Implements a faster method for masking
  • Add max_cloud_safe argument to sen2r()
  • Add a function safe_isvalid() to check for valid SAFE archive names, and use it to filter existing SAFE folders (#104)
  • Update installation documentation (Linux dependencies and Docker)


  • Important fix: fix indices computation (before that, indices with additive values were wrongly generated).
  • Avoid errors when a SAFE directory exists but not in the right format
  • Fix the fiddly error which caused several blocks when starting s2_merge() or s2_calcindices()
  • Fix searching oldname products with “auto” corr_type
  • Fix loading a custom mask from json parameter file
  • remove duplicated EVI2 index
  • #112, #115, #120, #124, and others

Version 0.3.3 Unreleased

This is an improvement of version 0.3.2, with several fixes and improvements.

Major changes

  • Add internal logging (argument log of function sen2r())
  • New function s2_dop() to know the Dates Of Passage over orbits
  • Cloud mask can now be smoothed and buffered, both using sen2r() and the GUI
  • Add apihub parameter in sen2r() and in the GUI: It is now possible to specify a custom apihub.txt file for specific executions (i.e. for scheduled processes).


  • Minor edits in GUI
  • Parallelise functions and manage errors
  • Create load_binpaths() (#87: Create a function to load paths of external executables and adapt other functions to use it.
  • Implement search for ingestion date
  • Split names_missing into names_cloudcovered and names_missing
  • Add some burn indices and update spectral indices from IDB
  • Change some function names (s2_getMetadata -> safe_getMetadata; s2_shortname -> safe_shortname; fs2nc_getElements -> sen2r_getElements)


  • Ignore baseline in computing required SAFE names
  • Fix #82 (Now BOA and TOA uses GTiff intermediate files instead of VRT (gdal_calc failed using vrt as input, computing only the first band))
  • Uniform some default argument values
  • Various fixes

Version 0.3.2 Unreleased

This is an improvement of version 0.3.1, with several fixes and improvements.

New functions

GUI changes

  • 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.

Processing chain

  • 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:

    • add partial parallelisation in s2_calcindices() (on infiles, not on indices);
    • add “parallel” argument in sen2r() to allow singlecore mode;
    • fix parallel=FALSE in function (force n_cores=1). In general, now the whole processing chain can be optionally launched in single core.

Addition to existing functions

  • 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.

Other changes

  • Update to sen2cor 2.5.5, and manage S2A L2A operational products (

  • 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.

Major fixes

  • 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.

Version 0.3.1 Unreleased

This is an improvement of version 0.3.1, with several fixes and secondary improvements:


  • 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)

Version 0.3.0 Unreleased

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.

Version 0.2.0 Unreleased

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.
