Parameters:
DESCRIPTIONr.tile retiles an existing raster map with user defined x and y tile size.NOTESr.tile generates a separate raster for each tile. This is equivalent to running g.region along with r.resample in a double loop.The module can be used to split a large raster map into smaller tiles, e.g. for further parallelized analysis on a cluster computing system. The overlap is defined in rows/columns. EXAMPLERetiling example for the North Carolina DEM:g.region raster=elevation -p # rows: 1350 # cols: 1500 # generating 2 x 2 = 4 tiles (width=1500/2, height=rows/2) r.tile input=elevation output=elev_tile width=750 height=675creates 4 tiles with the prefix elev_tile (named: elev_tile-000-000, elev_tile-000-001, elev_tile-001-000, ...).
