Use GDAL from R Console to Split Raster into Tiles
When working with raster datasets I often encounter limitations caused by the large size of the files. I thus wrote up a little R function that invokes gdal_translate which would split the raster into parts.
The screenshot to the left shows a raster in QGIS that was split into four parts with the below script.
## get filesnames (assuming the datasets were downloaded already. ## please see http://thebiobucket.blogspot.co.at/2013/06/use-r-to-bulk-download-digital.html ## on how to download high-resolution DEMs) setwd("D:/GIS_DataBase/DEM") files
