GDAL_resample: Resample raster

In MirzaCengic/gdalR:

Description

Function does a system call to run gdal functions (works on unix systems where gdal can be called from terminal). Use only file path, function will not work with raster objects loaded in R environment.

Usage

GDAL_resample(infile, outfile, target_resolution, method,
  large_tif = FALSE, return_raster = FALSE)

Arguments

infile	Raster to be cropped (file path or Raster object). Input raster should be stored on disk for GDAL access.
outfile	Path and filename of the mosaicked output (format "E:/Folder/file.tif").
target_resolution	New resolution of raster.
method	Resampling method. One in c("near", "bilinear", "cubic", "cubicspline", "lanczos", "average", "mode", "max", "min", "med", "q1", "q3").
large_tif	Use large_tif = TRUE for large rasters (>4GB).
return_raster	Logical. The function stores the raster in the filename argument path as a side-effect.

Value

Raster object. Only if return_raster = TRUE. Otherwise, the function side-effect is to save the file locally.

Examples

lc_info <- "/vol/milkun1/Mirza_Cengic/Data_RAW/ESA_CCI/TIFF/YearByYear/ESACCI-LC-L4-LCCS-Map-300m-P1Y-2002-v2.0.7.tif"
out <- "/vol/milkun1/Mirza_Cengic/Projects/Land_use/Data/Predictors/Resampled/Soil_GDAL/Soil_AWCh.tif"
awch <- "/vol/milkun1/Mirza_Cengic/Projects/Land_use/Data/Predictors/Original/Soil/Soil_AWCh.tif"
res_lc <- rgdal::GDALinfo(lc_info)["res.x"]
GDAL_resample(awch, outfile = out,
target_resolution = res_lc, method = "average", large_tif = TRUE)
