DESCRIPTION

47       r.tile retiles an existing raster map with user defined x  and  y  tile
48       size.
49

NOTES

51       r.tile  generates  a separate raster for each tile.  This is equivalent
52       to running g.region along with r.resample in a double loop.
53
54       The module can be used to split a large raster map into smaller  tiles,
55       e.g. for further parallelized analysis on a cluster computing system.
56
57       The overlap is defined in rows/columns.
58

EXAMPLE

60       Retiling example for the North Carolina DEM:
61       g.region raster=elevation -p
62       # rows:       1350
63       # cols:       1500
64       # generating 2 x 2 = 4 tiles (width=1500/2, height=rows/2)
65       r.tile input=elevation output=elev_tile width=750 height=675
66       creates  4  tiles  with the prefix elev_tile (named: elev_tile-000-000,
67       elev_tile-000-001, elev_tile-001-000, ...).
