In sustainablefarms/sflddata: Data Extraction Methods for the Linking Data Project

Extract a brick of Australian Albers Tiles.

Description

Uses the files stored at the given location, and assumes the tiles are saved as EPSG:3577, which is GDA94.

Usage

fetch_brick_Albers(
  spobj,
  years,
  get_tile_filenames = get_bggwtile_filenames,
  tilereader = bggwtilereader
)

Arguments

spobj	Spatial* or sf object that informs extents of the raster to extract
years	Years of data to extract
get_tile_filenames	A function with arguments (tilecode, years, ...). For a given tilecode and years it must return a list of filenames. Each filename is for the tile for each year provided.
tilereader	A function that accepts a single argument, 'filename', and returns a raster object for that file.

Value

A raster brick with extent equal or larger than extent(spobj), snapped to the cells of the raster data. The projection of the returned raster is EPSG:3577, which is GDA94. Extent of the returned value is a rectangle, and pixel values outside spobj are included.
