insecticide_index: Calculate bee landscape indices

In land-4-bees/SpeedyBeeModel: Calculates indices of landscape quality for bees

Calculate bee landscape indices

Description

New implemenatation of landsacpe insecticide toxic load index (Douglas et al.). Uses FFT convolution to improve runtime.

Usage

insecticide_index(
  output_dir,
  landcover_path,
  pesticide_path,
  forage_range = NA,
  guild_table = NA,
  ins_method = "mean",
  agg_factor = NA,
  normalize = F,
  useW = F,
  check_pesttable = T,
  rastertag = "insecticide",
  verbose = T
)

Arguments

output_dir	Path to directory for output files.
landcover_path	Path to land cover raster, including base file name
pesticide_path	Path to pesticide load by land use table
forage_range	Foraging range (in m) to use for distance weighting insecticide scores surrounding focal cell.
guild_table	Bee community to use to model foraging activity. Includes foraging range and relative abundnace of each species.
ins_method	Insecticide toxic load measure to use. Specify 'oral', 'contact' or 'mean' (mean of 'oral' and 'contact').
agg_factor	Aggregation factor for large rasters (use 4 to convert 50m to 120m resolution CDL)
normalize	Normalize values by the number of cells within each moving window?
rastertag	Text string to include in name of output raster, optional
verbose	Include more log messages from model run?
