Get the map parameters used on the eBird Status and Trends website to optimally display the full annual cycle data. This includes bins for the abundance data, a projection, and an extent to map. The extent is the spatial extent of non-zero data across the full annual cycle and the projection is optimized for this extent.
load_fac_map_parameters(path)character; directory that the Status and Trends data for a given
species was downloaded to. This path is returned by ebirdst_download()
or get_species_path().
A list containing elements:
custom_projection: a custom projection optimized for the given species'
full annual cycle
fa_extent: an Extent object storing the spatial extent of non-zero
data for the given species in the custom projection
res: a numeric vector with 2 elements giving the target resolution of
raster in the custom projection.
fa_extent_sinu: the extent in sinusoidal projection
abundance_bins: abundance bins for the full annual cycle
