rOPTRAM 0.3.2 (2026-02-14)

New Features

* Bumps to version 0.3.2.

BUG FIXES

* The evalfunction that calculates STR now rescales raw Sentinel-2 values 
within the script, rather than after the STR function. 
* When setting `rm.hi.str` the option was applied for each input raster separately.
This allowed for a case when one raster had very high values,
those values would be included in the final VI-STR table,
even though they would be above the high STR if the cutoff was calculated
for the whole table. This is fixed, such that high STR are removed 
after merging all raster values.

rOPTRAM 0.3.1 (2025-06-10)

New Features

* Bumps to version 0.3.1.
* Adds new option `area_cover` to set minimum coverage of the AOI by sentinel tile.
* Checks for length of image list returned by `SearchCatalog`. If no images are left, exits gracefully.
* Removed uncessary dependency on `MASS` package.
* Changes evalscripts to download indices in INT16 datatype, to save both CDSE processing units and download time.
  (Indices are scaled back to range (-1.0, 1.0) after download.)

rOPTRAM 0.3.0 (2024-08-15)

NEW FEATURES

* Adds option to filter out clouds, cloud shadows, water, using the Sentinel-2 SCM mask layer.
* Implements check for existing STR and VI files to avoid downloading again and overwriting. 
* Adds option to save list of images from CDSE::SearchCatalog after filtering for max cloud cover.
* Adds option to set output resolution of downloaded images.

BUG FIXES

* Fixes error in optram_safe(), offered by @kiviarttu:  [github issue][https://github.com/ropensci/rOPTRAM/issues/4]

rOPTRAM 0.2.0 (2024-07-02)

NEW FEATURES

  • Implements optram_options() function to allow setting many algorithm options that are applied throughout the model.
  • Implements four coloring options for the VI-STR scatter plot: colors by point density, colors by a categorical attribute column in the aoi polygon, colors by image date, uniform color with contour lines of point density,
  • Adds tileid (Sentinel-2 tiles) to downloaded images. This allows to save images from adjacent tiles when an AOI extends beyond a single tile.
  • The CDSE function GetArchiveImage() has been deprecated. This version of rOPTRAM uses the new GetImage() function.

rOPTRAM 0.2.0 (2024-06-06)

FIRST RELEASE ON ROPENSCI

rOPTRAM 0.1.0 (2024-04-30)

INITIAL RESPONSE TO REVIEWS

NEW FEATURES

  • Implements three curve fitting algorithms to determine OPTRAM trapezoid.

MINOR IMPROVEMENTS

  • Removes unnecessary tests.
  • Requires user to input area of interest as \code{sf} object.
  • Plot of trapezoid returned as \code{ggplot2} plot to allow user to apply further tweaks.

BUG FIXES

  • Fixes path to images in vignettes

DOCUMENTATION FIXES

  • Fixes documentation regarding download with \code{CDSE} package
  • Edits in keeping with r-lib guide.
