A data frame containing descriptive metadata for each of the 31 biome
classifications shipped with the package. Each row corresponds to one
biome layer in the raster stack returned by biomes_get(), in the same
order. The metadata is derived from the inventory compiled by
Fischer et al. (2022).
Format
A data frame with 31 rows and 12 columns:
- publication
Original publication of the biome scheme.
- name_of_classification
Full name of the biome scheme.
- criteria_for_biome_assignment
Criteria used to assign biomes.
- methodology
Methodology used to derive the biome classification.
- scheme_number
Biome scheme number (1-31); index of the corresponding layer in the raster stack returned by
biomes_get().- background_and_specifications
Free-text background information about the classification scheme.
- number_of_biomes_zonal_azonal
Total number of biomes in the classification, with the split between zonal and azonal biomes in parentheses.
- cover_deviation_percent
Deviation of the total area covered by this classification from the mean area of all 31 classifications, in percent.
- original_file_format
File format of the original data source (e.g. raster, shapefile).
- source
URL or citation of the original data source.
- access_date
Date on which the original data source was accessed.
- biome_definition
The concept on which the scheme delimits its biomes, one of
"climate","vegetation","land_cover","ecoregion","integrative"(a synthesis of several criteria or data sources), or"anthropogenic". Used bybiomes_rank()to rank schemes within the group sharing one biome definition.
