Create a raster spatial raster layer from a dataframe and a bounding box

Description

This function creates a raster spatial raster layer from a dataframe and a bounding box.

Usage

createRasterLayer(
  dfr,
  col,
  bbox,
  nx = 500,
  ny = 500,
  strCRS = get_proj4string("WGS84"),
  linear = TRUE,
  extrap = FALSE,
  duplicate = "error"
)

Arguments

dfr	spatial dataframe with data to rasterize
col	name of column in dataframe to rasterize
bbox	sf-style bounding box
nx	number of cells in y direction
ny	number of cells in y direction
strCRS	string representation of CRS in PROJ4 format (default yields long/lat in WGS84)
linear	flag passed to akima::interp
extrap	flag passed to akima::interp
duplicate	string passed to akima::interp

Details

Uses akima::interp(), sp::SpatialPixelsDataFrame(), and raster::raster().

Value

• raster raster layer

Note

TODO: this function should be revised to work with sf methods, not sp methods.
