amadeus 2.0.0

Major updates to code base - breaking changes have been minmized but please report if 1.3.x versions are not working as expected

• Refactored code base to improve maintainability and utilize modern R API designs and best practices
• The only breaking change that should affect previous version users is the process_tri() and calculate_tri() series.

Spatial and Temporal summarization with .by and .by_time parameters

• Added .by and .by_time parameters to all calculate_*() functions for consistent spatial and temporal summarization options across all datasets
• The default behavior of calculate_*() functions remains unchanged - i.e., no summarization, returning extracted or summarized values at the temporal resolution of the data - but users can now specify .by for spatial grouping (e.g., by HUC, county, state) and .by_time for temporal grouping (e.g., by year, month) to obtain summarized covariate values directly from the calculation step

‘frac’ option for categorical variable covariate calculation

• hms, koppen, and ecoregion datasets now have optional fraction covariate calculation that returns the fraction of each category in the radius buffer.

drop options for categorical variable covariate calculation

• hms, koppen, and ecoregion datasets now have optional drop parameter that will drop or exclude categories that don’t have any coverage in the radius buffer for a given point, which can help reduce the number of columns returned when many categories are possible but only a few are present in the area around the point.

Detailed vignettes for each dataset including available variables, spatial and temporal resolution, and example use cases

• workflow vignette for each dataset with detailed information on available variables, spatial and temporal resolution, and example use cases for each dataset

nhdplusTools use

• Moved nhdplusTools from Imports to Suggests and added requireNamespace("nhdplusTools") checks in all functions that use it

Additional MODIS products

• Added support for additional MODIS products with a focus on the burned area and active fire products

Finalize data API that were previously in development

• Added or completed the functonality for PRISM, EDGAR, CropScape, and HUC datasets

Use of GitHub Copilot for code generation and refactoring

• Used GitHub Copilot for help with code generation and refactoring across the code base, including function development, documentation, and unit tests; all generated code was reviewed and edited by the development team to ensure accuracy and consistency with package standards

Drought Index Support

• Added download_drought(), process_drought(), and calculate_drought() supporting three drought datasets:
  • SPEI (Standardized Precipitation-Evapotranspiration Index): multi-year netCDF files by accumulation timescale from https://spei.csic.es
  • EDDI (Evaporative Demand Drought Index): weekly files by accumulation timescale from NOAA PSL (https://downloads.psl.noaa.gov/Projects/EDDI/CONUS_archive/data/); legacy netCDF files from the CONUS_Archive path are also supported
  • USDM (U.S. Drought Monitor): weekly polygon shapefiles from https://droughtmonitor.unl.edu
• All three datasets are accessible via the top-level wrappers: download_data(), process_covariates(), and calculate_covariates() using aliases "drought", "spei", "eddi", or "usdm" for dataset_name / covariate.
• process_drought() returns a SpatRaster (SPEI/EDDI) or SpatVector polygons (USDM), both with CRS EPSG:4326.
• calculate_drought() supports .by / .by_time post-extraction summarization consistent with all other calculate_*() functions.

Migrate from wget/curl to httr2

• Completed migration of all download_* functions from httr/wget/curl command-line calls to httr2 for all network requests
• Deprecated download parameter (use default download = TRUE) and remove_command parameter across all download functions; both now emit informative warnings and are ignored
• Added hash parameter to all download_* functions for optional MD5 file integrity verification via download_hash() (using system md5sum)
• Added unzip and remove_zip parameters to download_prism() for post-download archive handling
• Added download_run_method() internal helper for unified httr2-based file retrieval with progress reporting, retry logic, and rate limiting
• Improved check_url_status() for general-purpose URL validation
• Expanded unit test coverage with mock-based tests for all download functions covering deprecation warnings, hash paths, and file-exists branches
• Added full variable reference to download_narr() documentation, listing all 88 available NARR variable abbreviations with descriptions grouped by category (monolevel, pressure level, subsurface); resolves #194
• Added download_narr() tests covering every variable abbreviation across all three variable categories
• Fixed download_data() dispatch to include "edgar" so download_edgar() is reachable via the wrapper function

amadeus 1.3.2

• Fixed deprecated file paths for NLCD, MODIS, and Ecoregions datasets
• Removed the certificate verification from ecoregion download which is not needed anymore
• For NASA datasets MODIS, VIIRS, and Geos-CF, added additional tags in the wget scripts to prevent API throttling
• httr upgraded to httr2
• Modified internal URL status check function for general use
• Added the news function to display the NEWS.md content within R pkgdown site
• Improved the reporting in the GitHub Actions workflows

amadeus 1.2

• future and future.apply dependencies were removed
  • nthreads argument is removed from calculate_modis_par() and calculate_nlcd()
• calculate_modis_par() is renamed to calculate_modis()

amadeus 1.1

• calc_*() functions are renamed to calculate_*() per naming convention of other function family in the package

amadeus 1.0

• First CRAN release (v.1.0.0)
