In hypertidy/vaster: Tools for Raster Grid Logic

GDAL RasterIO parameter creator

Description

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

Usage

rasterio0(
  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

rasterio0(c(0L, 0L), src_dim = c(24L, 10L))
