grid_rasters: Split two regional or national rasters into gridded tiles

In land-4-bees/beecoSp: Custom spatial functions for bee landscape ecology

Split two regional or national rasters into gridded tiles

Description

Split two regional or national rasters into gridded tiles

Usage

grid_rasters(
  rasterpath,
  rasterID,
  regionalextent = NA,
  div,
  buffercells = c(0, 0),
  NAvalues,
  writetiles = T,
  tiledir,
  verbosewrite = F
)

Arguments

rasterpath	file paths of input raster files
rasterID	text strings to identify output tiles (e.g. CDL for NASS Cropland Data Layer)
regionalextent	optional, vector of state names to crop national raster to region of interest
div	division factor specifying the number of tiles in x and y dimensions
buffercells	number of cells overlapping between adjacent tiles
NAvalues	No data or background values of input rasters
writetiles	logical, write tiles as directory of .tif files?
tiledir	path to directory where output tiles should be saved

Details

NAvalue parameter is used to identify raster tiles that are all background (e.g. areas of open water). These background tiles are excluded from list of output tiles and tile directory.

Value

A list of raster tiles. Each element of the list is a pair of raster tiles (one tile for each of the two input raster).
