In rooperc4/BottomFishingFootprint: Creates A Bottom Fishing Footprint From Spatially Explicit Effort Data

Description

This function takes a fishing effort data object (created by the footprint_data function) and makes a raster map of the effort data. The outputs are a raster stack with layers for each year group and gear type combination and a .png figure for each year group and gear type combination. The .png object is overlaid on a static google map of the eastern or western Pacific, based on the input longitude values of the data. The footprint_data_object must be a list including a data frame of raw fishing effort data (Fishing_effort_data), spatially, temporally effort data compiled by gear type (fishing_ footprint_table), the number of grid cells where their are not enough vessels represented to plot the data due to confidentiality rules (not_enough_vessels), gear type-year-year groups over which the data is summarized (years), gear types over which the data is summarized (gear_types), the spatial resolution of the data summary, #' the spatial resolution units (units) and the map projection of the data (map_projection). These 8 items are ouput from the footprint_data function. #'

Usage

footprint_map(footprint_data_object)

Arguments
