Version 1.6.0

Major changes

• Remove the possibility to search/download SAFE archives from ESA SciHub due
  to its discontinuation.
• Set "gcloud" as the default SAFE server.
• Begin voiding some functions related to ESA SciHub: s2_order(),
  safe_is_online(), *_scihub_login(),
  "scihub" methods in s2_list() and s2_download().

Documentation

• Partially updating the documentation to reflect the above changes.
• Remove old system requirements (#463).
• Remove old references to {rgdal}.

Version 1.5.5

Minor changes

• Add NMDI index, check NDMI and WDRVI indices.
• Remove suggested dependency {geojsonlint}.

Version 1.5.4

Minor changes

• Manage "s2cogs" (not yet implemented) value as source server.
• Change default path where Python's GDAL executables should be searched.
• Remove explicit {rgdal} dependency (https://r-spatial.org/r/2022/12/14/evolution2.html).
• Change maintainer's email in order to follow CRAN requirements.

Version 1.5.3

Bug fixes

• Fix CRAN errors related to GDAL version.
• Change maintainer's email in order to follow CRAN requirements.

Documentation

• Update invalid URLs (https://earth.esa.int/web/sentinel to https://sentinels.copernicus.eu/web/sentinel).

Version 1.5.2

Major changes

• Manage changes occurred in baseline version 04.00 (see #443):
  • retrieve offset values from metadata;
  • apply them to generate BOA/TOA products.

Minor changes

• Do not check for Google Cloud / SciHub status in s2_download() if not needed.

Bug fixes

• Fix extent_as_mask behaviour in sen2r() in case of GEOMETRYCOLLECTION type
  (threat as POLYGON, allowing masking).
• Simplify automatic tests: a variable full_tests is set to FALSE by default
  (in this case, only fast / strategic tests are run). Set to TRUE to run all tests.
• Minor fixes.

Version 1.5.1

Major changes

• Implement the possibility to produce rasters of angles information stored in the SAFE xml:
  • new internal (but documented) function s2_angles() to do it;
  • integration in s2_translate();
  • integration in sen2r();
  • tests and examples.
    (The GUI was not updated in order not to expose too much these products, since the package development is closed).
• Closing the support on GitHub issues, due to career change of the maintainer.

Changes in default values

• Change naming_convention default value in sen2r_getElements().

Minor changes

• Rename default branch master to main according to Git and Branch Naming.
• Add the naming convention "sen2r_new" to sen2r_getElements() (currently used only for internal usage).
• New argument tmpdir in s2_list().
• Allow s2_mask() to manage inputs with sen2r_new naming convention.

Documentation

• Add a note about GCloud download.

Bug fixes

• Fix error with multiple SAFE and single apihub (d62206e).
• Fix #423, #424, #425.
• Small bug fixes in smooth_mask().
• Test fixes (changes in system dependencies caused changes in tested values).

Version 1.5.0

Major changes

• Google Cloud integration to search and download SAFE Sentinel-2 archives (see https://luigi.ranghetti.info/post/safe-gcloud/):
  • implementation of methods within s2_list() and s2_download();
  • new functions check_gcloud(), is_gcloud_configured(), check_gcloud_connection()` to interface Google Cloud SDK;
  • integration in sen2r();
  • documentation;
  • new automatic tests.

Minor changes

• Restore check for existing equivalent SAFE products.
• Edit ENVI tags for BOA-TOA (band names, wavelenghts).
• 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

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

• New argument abort in s2_download() (see documentation).

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

Minor changes

• Use API URLs https://apihub.copernicus.eu/apihub instead of
  https://scihub.copernicus.eu/apihub as required after changes at
  SciHub side (https://scihub.copernicus.eu/news/News00868).
• Manage multiple SciHub credentials when ordering SAFE archives from LTA
  (experimental).

Documentation

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

Checks

• 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

Bug fixes

• Fix CRAN error (invalid example).
