HSItools 0.5.3

  • Breaking: hsi_bind_layers() is no longer exported (non-functional stub; design pending).

  • Breaking: removed hsi_merge_rasters; use hsi_bind_rows instead.

  • Added capture metadata sidecars: hsi_create_metadata(), hsi_write_metadata(), hsi_read_metadata(). One flat YAML file per capture, 32-field schema (v1.1.0), only name required. Reader validates fields and the schema version on read.

  • All package errors and warnings now carry the hsitools_error / hsitools_warning condition classes, so they can be caught and distinguished from {terra}/GDAL or base R conditions programmatically.

  • Internal validation helpers (check_* family) unified; list inputs now report all offending elements in a single error instead of failing on the first.

  • Fixed hsi_read_metadata() pointing at the wrong argument name in filename validation errors.

  • Added hsi_tiled() for parallel tiled processing of larger-than-memory rasters ({mirai} workers, VRT mosaic, automatic BIGTIFF for outputs over 4 GB).

  • hsi_calc_reflectance now uses the matched-dark formula with independent white/target integration times.

  • Added spatial calibration and co-registration toolchain: hsi_calibration_from_scale, hsi_set_extent, hsi_find_extent, hsi_pixels_to_units, hsi_drop_crs, hsi_check_gcp, hsi_match_gcp, hsi_coregister.

  • Added MNF: hsi_calc_mnf / hsi_apply_mnf.

  • Continuous integration on five platforms (Linux devel/release/oldrel, macOS, Windows) via GitHub Actions, including Quarto vignette builds (skipped on Windows CI due to an upstream quarto limitation; verified on the other platforms).

HSItools 0.4.0

  • Major functions now live in separate files.

  • Created first vignette “Basic HSItools workflow”.

  • Fixed and improved RABD calculation speed with hsi_calc_rabd

  • Added hsi_calc_rsd for calculation of reflectance standard deviation per pixel.

  • Added hsi_calc_rcv for calculation of reflectance coefficient of variation per pixel.

  • Added hsi_calc_rmedian for calculation of median reflectance per pixel.

  • hsi_calc_reflectance gained in_memory argument to process everything in memory, if it is available. This needs user’s control and knowledge of their OS and hardware.

  • Plotting got split into separate files, too.

HSItools 0.3.0

  • Ditched the shiny app.

  • Dropped heuristics for file naming, hardcoded paths etc.

  • Most SpatRasters now use default names from {terra}.

  • Reflectance calculation is no longer based on aggregate / disaggregate functions and resampling.

  • Most functions gain hsi_ prefix.

  • Unified arguments where possible.

  • Introduce tests for some functions.

  • hsi_smooth_savgol now uses {gsignal}

HSItools 0.2.0

  • Last release with a shiny app.

HSItools 0.1.0

  • Initial GitHub.
