raster_io {affinity}

GDAL RasterIO parameter creator

Description

Basic function to create the window paramers as used by GDAL RasterIO.

Usage

raster_io0(
  src_offset,
  src_dim,
  out_dim = src_dim,
  resample = "NearestNeighbour"
)

Arguments

src_offset

index offset (0-based, top left)

src_dim

source dimension (XY)

out_dim

output dimension (XY, optional src_dim will be used if not set)

resample

resampling algorith for GDAL see details

Details

Resampling algorithm is one of 'NearestNeighbour' (default), 'Average', 'Bilinear', 'Cubic', 'CubicSpline', 'Gauss', 'Lanczos', 'Mode', but more may be available given the version of GDAL in use.

Value

numeric vector of values specifying offset, source dimension, output dimension

Examples

raster_io0(c(0L, 0L), src_dim = c(24L, 10L))
