GBIF es50

Work on es50 maps for GBIF.

Scripts below for making simple hexagon es50 maps for any taxonKey using the api

installation

library(roperators)
library(dplyr)
library(dggridR) # used to make hexagon grid
library(magrittr) # for %T>% pipe

taxonKey = "789"
spacing = 300 # space between hexagon grids in miles I think 
facet = "speciesKey" # which rank to use... # can also be genusKey

grid = dggridR::dgconstruct(spacing=spacing, metric=FALSE, resround='down') %>%
gbifrasters::getPolygonGrid(spacing,landOnly=FALSE) %>% # get from entire globe
gbifrasters::getData(taxonKey,facet=facet) %T>%  # get data from GBIF using facet api
saveRDS(file="C:/Users/ftw712/Desktop/grid.rda") # save data because it takes a while usually...

# grid = readRDS(file="C:/Users/ftw712/Desktop/gridTest.rda")
